Hi - glad to have another geologist on board. And some of us US geologists do have a bit of deep training in economic geology :-)
Also thanks for the work on Hydrothermal circulation, that one has been on my to do list for awhile. Cheers, Vsmith 04:59, 16 December 2005 (UTC)

[edit] Chiro

Hi .. I guess somebody must have misguided you. The problem we have with chiropractic has actually nothing to do with back pain treatment. In your case, the chiropractor is treating you like a physiotherapist and this is acceptable. The problem we have with chiro is that it claims, it can cure all diseases by treating vertebral subluxations. This is clearly a nonsense. ackoz 09:50, 21 April 2006 (UTC)

[edit] Alps

Hey Rolinator! I understand you are a geologist from Austria. I have just written a couple of articles on the geology of the Alps, I wondered if you could read them through for me. I am a geologist myself but I have never done research on or in the Alps. Much of what i wrote can be untrue or oversimplified, so I would appreciate it if you can look at it. Thanx! Woodwalker 09:19, 8 June 2006 (UTC)

[edit] Natural hisotry

If I remember correctly you asked me ages ago about the Natural history of Australia article I had in my user space. I've moved it to the main name space and would appreciate any help you can offer expanding the text. The main focus of the article isn't really the geology (you've got that covered :) ) but how geological and climatic events effected the flora and fauna.--Peta 08:25, 14 July 2006 (UTC)

[edit] Sorely in need of geological help

Have been translating 'anorthosite' article into French Wiki. Reader frowned on An40, An60, asked for elucidation. No clue. Any idea ? Help appreciated Anne97432 05:23, 16 September 2006 (UTC)

Anne,

The An number (An#) refers to the modal percentage of anorthite within the solid solution series Anorthite-Albite (anorthite being 100% calcic (Ca) plagioclase and albite being sodic (Na)). An40 would mean a plagioclase composition of 40% anorthite and 60% albite by cation percentage. See the plagioclase page. Plagioclase, by definition, comprises >90% of anorthosites.

Most rocks with >90% plagioclase are composed of anorthite plagioclase with An# of 80+; it is very very rare to find rocks with >90% albite-normative plagioclase (these are essentially tonalite-tronhjemite granites).

Hope that helps, as although i am argumentative and would go in to bat for you, I can't speak French to save my life. Rolinator 08:51, 16 September 2006 (UTC)

[edit] Yes, it does help :)

Of course, I don't understand what it actually means, but now I can add a solid footnote, that should keep him quiet for a while while he tries to figure it out :). And if you ever need help from the French into English, be my guest ! (same pseudo on French wiki). Anne97432 09:51, 16 September 2006 (UTC)

[edit] Subducted stuff

You probably already saw my question about subduction, please wait a few days before answering. I want to see if someone else has something to contribute (and I hope it's not a Russian quotation). Try to summarize, and I'll probably need clarification on some issues but if there are delays in the exchanges it might help draw in details from others which might otherwise be missed. I'm aware of some issues in the carbon cycle and water cycle, but don't know how outdated my info is. (SEWilco 04:29, 1 October 2006 (UTC))

I'll add some stuff to that question, probably on Friday. (SEWilco 06:05, 5 October 2006 (UTC))

[edit] Methane vs slag?

I thought there was something familiar about the "Carbonate reduction" components. There are similarities with the blast furnace reduction of iron, but Scott2004 did not provide silicon so no calcium silicate could form. Silicon and calcium are both lithophiles, and I suspect where calcium is found in the mantle the more common silicon is probably also present. Would silicon being available promote many of the reactions which remove FeO from subducted crust? (SEWilco 05:48, 1 October 2006 (UTC))

I think you are starting to see where there is some problems relating artificial reactions to the mantle. But to answer your question...round about ways anyhow, I've had a read up on wustite. It is found in metamorphosed Mg-rich limestones (ie; dolomites) in conjunction with periclase (MgO); periclase typically hydrates to brucite, a common mineral in high-MgO ultramafic rocks which have been hydrated (but absent in the main from talc carbonate metamorphosed ultramafic rocks).

I see the problem of getting wustite and calcite in the mantle firstly, for prolonged periods of time, and secondly in great volume, relates to the propensity for CaO to react with silica.

In the mantle, if hypothetically you had

1. olivine + water + CO2 --> magnesite + silica +/- talc, in the presence of the carbonate reduction reaction
2. Calcite + water --> CaO + CO2 + H2O --> CaO (FeO) + CH4

is that the byproduct of reaction 1 (silica) then knocks on into reaction 2's CaO and you would, probably, get CaFeSiO_x, or probably a pyroxene. If you substitute some MgO for FeO as the catalyst you merely make a more or less fe/mg rich pyroxene.

It is theoretically possible to avoid this by using siderite, to remove the Ca from the system and stop pyroxene formation, but it then is arguable that at 1200 degrees and GPa of pressure, that excess FeO turns into olivine again. Remember that prograde metamorphism of dunite, starting from the upper crust and going down, progresses through serpentine minerals, to serp-pyoxene, serp-pyrxene-amphibole and eventually up to metamorphic olivine again once the most stable mineralogical configuration of hat composition is olivine at a given T-P condition (upper amphibolite to granulite facies, generally).

Siderite isn't a usual mantle mineral. While it is difficult to physically mix a rock such that any carbonates become mixed with silicates, making Ca silicates (pyroxene) it is more likely that small scale melting of the rock occurs during subduction, which removes volatiles and incompatible elements. This is generally manifesting as back-arc volcanism and arc volcanism, as the subducted slab is dehydrated. Thus, by the tme a hypothetical carbonate-bearing oceanic slab hits the mantle, it has been metamorphosed and subjected to dehydration reactions, melting and so on. It is unknown if a potentially wustite-calcite bearing carbonate rock could survive this sort of treatment enroute to the mantle. It would be much simpler to assume not.

This is why i keep coming back to serpentinites; they exist at T-P conditions which favor abiotic methane generation; this is observed as current day methane in metamorphosed ultramafics, and they contain the appropriate transition metals and are reduced enough to chemically promote reduced carbon. The Scott experiment is a good argument that it is plausible, but it lacks applicability to real-world processes and compositions. Rolinator 08:28, 1 October 2006 (UTC)

There's a term (which escapes me at the moment...trans*?) which is used to refer to FeO being removed from subducted slabs. I have the impression that this removal happens at less depth than would be expected for FeO-related alterations. Is it known if this removal involves formation of FeO within slab material, which then may react with things while it moves out? Or does FeO form around the outside where contact with mantle material causes reactions which cause the removal from the slab? (SEWilco 04:46, 3 October 2006 (UTC))

Dehydration metamorphism (ie; blueschist metamorphism) involves altering the subducting oceanic crust; this includes the sediment, basalt, sheeted dyke-peridotite and lower slab dunite (typical ophiolite stratigraphy), the upper portions of which are likely retrograde metamorphosed during the eruption-rifting phase (ie; hydrothermal circulation) into serpentinites.

Blueschist metamorphism generally involves loss of volatiles, conversion of amphibole-chlorite seafloor metasomatism into Na-rich metamorphic amphiboles (glaucophane etc) with a loss of Ca, and potentially a change in the FeO:Fe2O3 ratio (ie; redox change). I'm not aware of whether the subducted slab becomes more FeO rich or less.

The mantle wedge, above the subducted slab, is the beneficiary of the volatiles and Ca which are driven off the slab. Hence, calc-alkaline magmas or arc magmas are generated. The granites formed under, for instance, the Izu-Bonin arc of Japan, tend to be calc-alkaline in character, potassic, and form two series. A "reduced" ilmenite bearing suite, and a "oxidised" magnetite bearing suite.

When I looked into granite gold metallogenesis, the ilmenite-magnetite divide is important because, the redox state of a granite is critical for which elements are able to be concentrated into ore deposits. However, I say "reduced" granites because both suites sit above the Wustite-Magnetite redox buffer and below the QFM redox buffer. The transition to ilmenite from magnetite is, from the work of various authors, a contribution from subducted slab sediment, generally rich in reduced carbon (graphite is reported from some ilmenite-series granites, which are the S-type of Chappell and White), a contribution from back-arc deplated mantle (which produced more Ti-rich melts, be they boninite basalt or granite) and a contribution from metasomatised mantle wedge and slab melts. The speciation between ilmenite and magnetite is thus complex, not just related to FeO and the slab itself.

This breakdown of the two granites implies that redox conditions and contributions of oxidised vs reduced materials changes with distance from the subduction zone. But it isn't really well understood, and it is also difficult to say whether the redox change in the granites is caused by the slab or what melts above the slab as it heats up. I would hedge my bets on the latter. But again, these two granite suites have different states of oxidation relative to one another within the confines of the two redox buffers. Also, the fact you can get graphitic granite argues that whenever organic detritus interacts with magma, it is equally likely to fix in the ultra-reduced conditions, and may actually prevent methane generation due to lack of ability to drive the bulk chemistry into conditions which change carbon from graphite to methane (ie; its so reduced that it takes a long while to push it into methane-carbon dioxide redox compositions). Then again, these granites are derived from melted sediments, so clearly carbon in them is entrained in solid form, not percolating through as CO2 gas.

In fact, if a granite is reduced enough, it will force all FeO into silicates, preventing any Fe oxide formation (lets say pyroxene and amphibole), which also cancels out any potential methanogenesis reactions involving wustite. Whether this means that slab melts can't form wustite-carbonate during subduction is another problem, because so far there's no evidence of this actually happening. In theory, yes. But there is no evidence. The only known carbonatite volcano also sits in a rift zone, so if a carbonate sequence melts (lets say to provide a reduced ilmenite granite), we are on current evidence unlikely to see it manifest as a carbonatite. I don't know if that answers anything, but the redox state of basalt melts behind subduction zones is something I'm not at all familiar with, and that is much deeper melting in much more mafic magmas.

[edit] Gold in fluids

Unrelated to other discussions, I point out this URL because it mentions gold in fluids in the crust. Thought you might be interested, although it's likely you already know of it. http://volcanoes.usgs.gov/staff/jlowenstern/other/volatile_reviews.html (SEWilco 05:05, 8 October 2006 (UTC))

Thanks, but you are right. Lowenstern's stuff is known to me. Thanks for the thoughts. Rolinator 00:14, 12 October 2006 (UTC)

[edit] Primordial water

Is there a reason you blanked Primordial water rather than moving it? Do you think the content is worth moving to a better title, or redirecting to a similar term? Please reply at Talk:Primordial water. By the way, there's a deletion process you can use if there are pages you think need permanent deleting. Angela. 04:07, 19 October 2006 (UTC)

Consider an AfD. I'll be happy to help you start one. - CrazyRussian talk/email 05:34, 19 October 2006 (UTC)

A brief response as I am @ work; I think (?) I explained on the talk; there is no practicable scientific method of ascertaining if water from the mantle is primordial in a cosmochemical sense; only the volatiles carried with the water. Mediate the crap out of it if you want in the meantime, I'll be back in from fieldwork in a week. It was also a topic AFAIK with only a couple of links, one of which was hydrothermal vent, where it was used in isolation and without any basis in fact aside from the point raised directly above.Rolinator 05:09, 20 October 2006 (UTC)

[edit] Soil science vs Engienering, Cone penetration test

Hi! I'm a little curious why you changed Cone penetration test from a geology-stub to a soil-science stub? Soil science, in my experience, generally refers to a branch of agronomy, which the CPT is not used for (usually). Argyriou (talk) 17:25, 29 October 2006 (UTC)

There is very little to no useful data to be gleaned from the majority of geological science in knowing how compacted soil is; pedologists would probably use the CPT more than someone studying volcanic rocks or metamorphism, yes? Its either that or engineering, civil or otherwise. I have been finding that geology-stub is applied to anything to do with anything at all and, being a geo, tend to try to find a substitute for things which aren't anything I have heard of in my geology experience. Like this, which is probably a civil engineering test. Cheers. Rolinator 23:05, 29 October 2006 (UTC)

Cone penetration test is definitely an engineering test; and the article is tagged as an engineering-stub. The CPT is sometimes useful in engineering geology, and as it can be fitted with shear and pressure wave receivers, can also be useful in seismology, but it is primarily for engineering. I'll remove the soil-science-stub, and leave it as only an engineering-stub. Argyriou (talk) 23:18, 29 October 2006 (UTC)

Every so often I go through the geology stubs and weed them down into minerals, soils, engineering, skiing, etc, because I figure that if an article is stubbed properly then it will reach an audience who knows how to expand it. So thanks. Rolinator 23:20, 29 October 2006 (UTC)

[edit] Lava

I've just been reading the Lava page. It's really good. There was some discussion about putting it up as a featured article. I've just been through that experience, which was not at all pleasant. It just happened that the first two peopl who commented on my article were not interested in subject matter (didn't appear to be, anyway!) but merely in whether the article conformed to the Manual of Style (which it didn't.) They were also very critical about the fact that even though it had a Bibliography of I can't remember how many books, it only had a few inline cites. They wanted literally everything to cite a book, not just those comments that might need backing up but simple facts like "lava is hot stuff that comes out of volcanos". Some Featured articles only have the cites that are necessary, but if it is reviewed by a real pedant, it's not worth the effort. My article ended up with about 80 inline cites until I got fed up and deleted quite a lot of them.

Anyway, my suggestion is, put your references in and also give examples of things like speed. They don't have to be exact. It's OK to say "the larva flow may advance at less than 5 kilometers an hour".

Best of luck! --Amandajm 13:50, 15 December 2006 (UTC)

Nah, stuff it. You're right, too much effort required. It can be a little gem of quality, with its own charming flaws, in amongst the dross of Wikipedia, without needing to be a featured article.Rolinator 00:10, 16 December 2006 (UTC)

[edit] welcome

To the WA project (my random welcoming system in operation here - buit like my unfinished stub on Mount Read Volcanics) hope you enjoy it - you might be the only geol we have - so be prepared for questions! SatuSuro 13:35, 21 December 2006 (UTC)

I've worked for scintrex (v short time) v long ago - at mt lyell when it still was - usually as a gfa (multiple meanings there) - and still have a thing about west tas - hence my west coast range art (which is very weak on the geology) - but what I was going to say - is that when you create a west poz art - on the talk page - look at the arts of yours that I have just tagged - add those - it makes sure theyre in there in the wa project! SatuSuro 13:43, 21 December 2006 (UTC)

Also I was on scholarship in canberra in 1997 and an old friend from Darwin NT had written a brilliant article on archaeology and crazy ideas - I must find it/him - as it would fit into the age of earth arguments as a bit of science i suspect!

I always like the way pop sci folks play with the north pole sequence for the age of life on earth alone...  :) SatuSuro 14:05, 21 December 2006 (UTC)

Can I also bid you welcome! Will spend sometime reading articles linked to you, very interesting. Your contribution to WP:WA would be indispensable, esp. geology component in general articles. I'm trying to improve dampier/ karratha articles at the moment as readers may be looking them up (gas pipeline). Regards Fred.e 18:25, 21 December 2006 (UTC)

[edit] Petrology

I just added more stuff to Petrology, and I have a better feeling of your understanding of what's going on down there. You're working with the background of what patterns have been noticed of rock behavior around the globe, while I've often poked at bits of chemistry which haven't been generally noticed so probably aren't common. The conditions where the mass of observations has problems is when there's a faulty assumption (such as if we'd noticed asteroid impact events before discovering Yellowstone and accepted Yellowstone as an impact crater) or missing information (such as the fellows in 1911 who noticed magma differentiation but didn't know about plate subduction). The hunt for understanding goes on. (SEWilco 09:14, 24 December 2006 (UTC))

[edit] "Mineral redox buffer" discussion

Please check discussion page for plan for suggested changes. Note especially the proposal to delete sulfide-sulfate material from this entry and to have someone create a new entry to treat sulfides and oxidation in greater detail -- but I am not qualified to create such an entry on sulfides. Could you and would you do so, if I made extensive changes to the redox buffer entry? My background does include use of oxygen buffers and calculation of oxygen fugacities, and so eventually I might create a page on oxygen fugacities in geology -- if so, what should such a page be titled? Omphacite 18:56, 27 December 2006 (UTC)

Given it is late at night and I am a wee bit tipsy from egg nog and wine, I cannot answer definitively, but, the redox buffer page is indeed an imperfect grab-bag at the moment for the whole trio of concepts; redox buffers, fO2 and sulfide-sulfate systems. So go ahead and do whatever you feel neccessary and the only criteria for naming a page should be; brief and related to the subject matter. It could be oxygen fugacity (rocks) or similar.Rolinator 02:56, 28 December 2006 (UTC)

[edit] Talk:Australia (continent)

Hello and Happy New Year - just wondered if you were aware of the discussions at Talk:Australia (continent)? It is mostly semantics and conventions, but they are trying very hard to decide how to name and develop that article. I've tossed in a few things geological to help (??) them, but I wondered if you as a "local" might be able and willing to help them more than I can. Cheers --Geologyguy 04:32, 28 December 2006 (UTC)

[edit] Why is the plural used in clastic rocks?

Why does clastic rocks have a plural article title? Wikipedia:Manual of Style says the singular should be used except when there's a particular reason to prefer the plural (e.g. the Beatles, etc). Michael Hardy 23:48, 12 January 2007 (UTC)

[edit] Hamersley

Hello,

There's a push to get Hamersley, Western Australia to FA status. I've just added a section on natural history in which I have pretended to be a geologist. I'd appreciate it if you would at least check the geology bit for gross stupidity. If you're willing to improve it or fill in some red-links, they would be even better.

Cheers,

Hesperian 02:21, 22 January 2007 (UTC)

It wasn't too bad. Not much more to be said...and good luck!Rolinator 06:33, 22 January 2007 (UTC)

Thanks heaps. I had been trying to include a reference to Spearwood Dunes, but it didn't flow.

I might take a little bit out again. Deciding how much context to include in an article on a suburb is a bit of a balancing act. Perth Basin is certainly relevant, but I don't think defining the scarp is. Hesperian 06:45, 22 January 2007 (UTC)

[edit] Continental Crust

Hi! Kenorland article edit you wrote that "core formation occurred within 100Ma of earth fomation"? I really do wish you could find the article on this.

[edit] Lake Johnston Greenstone Belt

Hi again,
I've been working on Mallee (biogeographic region) recently, and it has been suggested that the Land Use section include discussion of mining. Lake Johnston is just inside the northern border of the region. If the greenstone belt and Emily and Maggie are roughly north of the Lake Johnston, then they are outside the Mallee region; if south of Lake Johnston, then they are inside the Mallee region, and warrant mention in the article. Any insights? Further discussion at Talk:Mallee (biogeographic_region)#opinion. Hesperian 12:29, 3 February 2007 (UTC)

The Lake Johnston Greenstone Belt continues south from Lake Johnston itself for over 80km. So Emily Ann and Mggie Hays are at the northern end of it, but the greenstone belt itself is quite large. Rolinator 07:49, 5 February 2007 (UTC)

Your recent article creation Carbonate hosted lead zinc ore deposits does not contain any references. Please cite your references for this article. Thanks ++Arx Fortis 04:07, 22 July 2007 (UTC)

Christ, you ridiculous pedant. DIY it on google.Rolinator 11:06, 25 July 2007 (UTC)

Oh, and I want you to spend six weeks tagging all the fricking stub articles for references. Why you don't can only be because there's 2.5 million articles on wikipedia where its OK to write one sentence and claim whatever the hell you want (i cite resource extraction) whereas if you put in more than one minute's effort, your efforts cop a citation tag and no doubt a pedant tacking on a deletion five minutes later. You heroes. I wish I was like you.Rolinator 11:09, 25 July 2007 (UTC)

Don't let 'em get to you. Thanks for writing the article - one more to cross off my to do list. :-) I've added a couple refs - won't satisfy Arx up there, but...
Also I have redirected the resource extraction thing to mining, as it was really a bit of junk. Hadn't run across it before. For a bit of humor, I note that it was written back in 04 by a user called Pedant - oh well...
Keep up the good work and don't let the pedants get to you. Cheers, Vsmith 13:59, 25 July 2007 (UTC)

Rolinator...I am surprised at such hostility from a polite request. I was trying to be civil. It's your contribution. Cite your own references. It's obvious you know more about the subject than I do, so I assumed you would have access to the appropriate reference material. (Not all references are accessible via "Google.")

I agree...there are way too many articles on Wikipedia without sources and that are, quite frankly, crap. That does not apply to the article that you created and you shouldn't compare it to those others. In keeping with the higher standard, references are apropos. At a minimum, references show that the article is not original research and removes the issue of "a pedant tacking on a deletion five minutes later" as you mention above. My motivation for encouraging citation was simply to assuage the possibility any such circumstance.

Lastly, I am not a pedant. I do not hold others to a higher standard than I do for myself. Any articles I've created, I've cited my own references and encourage others to do the same per the guidelines. ++Arx Fortis 03:44, 26 July 2007 (UTC)

[edit] Oil shale

Hi, Rolinator. Last year you added significant part of the geology section of the Oil shale article. As the whole article grew too big, recently we created several spin-off articles, including Oil shale geology. I wonder, if you could be interested assisting to improve this article, and also create appropriate summary for the geology section of the main article. As there is plan to nominate these articles for GA, I would like to ask your assistance to add inline citation for all hard data and facts. There are some tags where references are needed. Thank you in advance.Beagel 18:53, 6 August 2007 (UTC)

I listed Oil shale for the new peer review and related spin-off articles (Oil shale extraction, Oil shale geology, Oil shale industry, History of the oil shale industry, Oil shale reserves, Oil shale economics, and Environmental effects of oil shale industry) for the peer review. Your comments and edits will be most welcome. Beagel 17:58, 28 August 2007 (UTC)

[edit] Mantle Composition

Concerning your Wüstite "citation needed", I took the 7.5% FeO directly from the table "Composition of Earth's mantle in weight percent" under Mantle_(geology)#Characteristics. You can move your "citation needed" to that whole table, if you like. --Ben Best 02:32, 15 August 2007 (UTC)

Ben, there's a difference between FeO wt % and wustite weight %. You are inferring that all FeO in the mantle is present as wustite. This is not the case. Most FeO in the mantle is in fact present as olivine or pyroxene solid solutions. I'll edit it out. Rolinator 03:04, 15 August 2007 (UTC)

Thanks for your reply, Rolinator. My request for explanation/justification is at Talk:Wüstite. --Ben Best 05:06, 15 August 2007 (UTC)

[edit] Uranium Ore Deposits

Thanks for your article on uranium ore deposits. I will definitely pitch in to expand the article. Tharikrish 16:08, 20 August 2007 (UTC)

[edit] Wikiproject Mining

Hi Rolinator, I see that you add a lot of material to Mining and Geology. I am currently trying to start a wikiproject on mining if you would be interested in contributing. Thanks--Kelapstick 17:00, 28 August 2007 (UTC)

I think the mining pages are in a really desperately poorly organised state. I'll help where I can. Rolinator 06:27, 29 August 2007 (UTC)

For sure they are, I have spent the last couple days just sorting redundant categories, and am nowhere near half done. For the most part they are also in bad shape. Thanks --Kelapstick 12:49, 29 August 2007 (UTC)

Yeah, I noticed. Rolinator 08:49, 31 August 2007 (UTC)

[edit] Your edit to speciesism

Please be aware that talk pages are not for general discussions not related to improving the article. It's also convention that new comments go at the bottom of the page. I can't follow what your reasoning was with the comment, but speciesism can apply to any species. Richard001 08:33, 20 September 2007 (UTC)

It is, however, not applied in the article so much to carrots as it is to a neo-political construction by vegans and retards. By its very nature "speciesism" is a fallacy; if by the act of slughter or exploitation of another species for food or economic use a human is speciesist and thereby deserving of opprobium, clearly sharks are speciesists too and we shouldn't like them. Nor wolves, which are speciesist toward sheep last time I checked. Life feeds on life. If I don't make sense, its only because I'm on the sam wavelength as animal rights activists.Rolinator 04:42, 22 September 2007 (UTC)

[edit] Merge of coal mining and sub-surface mining

Hello! Beagel pointed me to where I can find you, as you are interested in articles regarding mining. I've started a discussion regarding the merger of sub-surface mining into coal mining - I'd appreciate your opinion. Cheers and thanks in advance! --Ouro (blah blah) 10:04, 11 November 2007 (UTC)

[edit] AfD nomination of Alluvial desert

An article that you have been involved in editing, Alluvial desert, has been listed for deletion. If you are interested in the deletion discussion, please participate by adding your comments at Wikipedia:Articles for deletion/Alluvial desert. Thank you.

Chop chop! My opinion is in the comments. Rolinator (talk) 12:28, 30 November 2007 (UTC)

[edit] Equal-angle and equal-area projections

Hi, Rolinator. An old comment of yours at Talk:Structural geology suggests that you are handy with Stereographic projection. Perhaps you also use the Lambert azimuthal equal-area projection for plotting data? Recently both of these articles have been improved, but the applications could always use more work, especially in the latter article. And Pole figure is pretty shabby. Just an invitation. Reply here if you like. Cheers -- Joshua R. Davis (talk) 21:35, 24 January 2008 (UTC)

I'll have a look. Unemployment lends one to wikipedia... :P Rolinator (talk) 22:56, 24 January 2008 (UTC)

[edit] Phreatomagmatic eruption

I have noticed your interest in geology in general as you edited some work of mine on the ignimbrite page, so i wonder if you wouldnt mind taking a look at this article that i created, and maybe giving some feedback on technicality, manual of style etc? First real edit so just want to know what is good and what is not. Would be much appreciated. Cheers Russjass (talk) 12:54, 18 May 2008 (UTC)

Awesome work. No real problems, just a few spelling/typo errors. Rolinator (talk) 09:23, 20 May 2008 (UTC)
