Hi. You are listed as a participant in WikiProject Geology. Maybe you to please consider helping to improve the oil shale article. This article has developed quite well, but some more expert assistance is needed. Thank you in advance. Beagel 17:33, 31 May 2007 (UTC)[reply]

Thank you adding the age of Scotland torbanite into oil shale article. As we are in the process of splitting this article, I moved this table into oil shale geology article. Maybe you would like to take a look on this article? Beagel 12:23, 28 July 2007 (UTC)[reply]

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 17:18, 28 August 2007 (UTC)[reply]

Hi, GeoWriter. I am going to nominate the Oil shale geology article for the GAN. However, I think this article probably needs some more editing and improvement before the nomination. Maybe you are interested to take a look on this article? Thank you in advance. Beagel (talk) 09:53, 21 June 2008 (UTC)[reply]

User:Resident Mario/Volcanism of Hawaii Workgroup Just here to say Yay for joining. I've seen you around the articles before. Currently, Loihi (me, Viriditas), Kīlauea (Ceranthor), and Hawaii hotspot (me) are in development. ResMar 16:51, 14 March 2009 (UTC)[reply]

Loihi, take two. ResMar 00:27, 30 May 2009 (UTC)[reply]

...for your edits to Hawaii hotspot. Sometimes a little trim is necessary, and I think the edits you have applied have improved the article. I was actually thinking of splitting "characteristics", but I'm not sure of the notability of such an article, as there is no precedence that I know of for such an article. But it is so long and wordy, I think that is what keeps people from commenting on these types of articles because they do not want to read the whole thing. The article failed FAC for this reason.

So basically, thanks for making the article shorter where it was necessary. I'm hoping to try again, if you would like to be listed as a co-nom, just let me know. You are currently 4th in contribs, if you make some more edits and catch up to us, it would be good to list you next time. --ErgoSum•talk•trib 01:22, 15 July 2009 (UTC)[reply]

Concerning your recent edit to Hawaii hotspot, it was brought up at FAC that 0.02 km3 (0.0048 cu mi) was harder to visualize than 20 cubic hectometers (26,000,000 cu yd). Personally, I'm not sure which I prefer, and I don't think its a big deal, but I thought you should know this may come up again. --ErgoSum•talk•trib 18:04, 18 July 2009 (UTC)[reply]

		The Volcanoes Barnstar
		This one goes to a dedicated editor who's been quietly improving the quite part of wikipedia that is volcanoes since...<waits for Special:Contributions to load> 2007! Hard to find a volcano article without your name on it somewhere :) ResMarHohoho 00:52, 2 December 2009 (UTC)[reply]

Hello. If you haven't noticed, I've started a structural reorganization of WikiProject Volcanoes. So far, I've beutified the head page and moved a lot of the stuff to subpages of the project, so as not to bulk the main page. As an active member of the project, this is just a notice about what's going on. Comments go on the talk page. Happy holidays, ResMar 14:08, 25 December 2009 (UTC)[reply]

Hi, GeoWriter, There is a discussion if all oil shales are shales or not. Your comments are appreciated. Beagel (talk) 07:49, 6 June 2010 (UTC)[reply]

Hi GeoWriter, thanks for helping out with List of 21st century earthquakes, it's a constant struggle against all those who want to put the earthquake that they felt into that list, or just the latest that they heard of on the news or from the USGS, no matter how insignificant. The lede is a lot clearer now, something that I'd been meaning to do for a while. Cheers, Mikenorton (talk) 19:10, 24 June 2010 (UTC)[reply]

I am glad to help. I expect it is quite big news for some people to hear about or feel an earthquake in their area, but if everyone included it on this list, the list would lose its impact. Hopefully, the guidance might steer at least some editors in the right direction. GeoWriter (talk) 19:41, 24 June 2010 (UTC)[reply]

I've opened a discussion at Talk:2010 Central Canada earthquake in which I'm trying to get views on the proposed earthquake article notability guidelines. On the basis of those guidelines the Central Canada quake article should be deleted, which probably won't win me many friends there. Maybe there is some merit in including something on population affected, but I fear that it would let too many of the little earthquakes back in and be heavily biased towards english-speaking areas. Mikenorton (talk) 19:59, 24 June 2010 (UTC)[reply]

BTW I have your talk page watched, so no need for the talkback. Mikenorton (talk) 20:01, 24 June 2010 (UTC)[reply]

Opening the discussion on the Canada quake is a good idea. I advise against "population affected" as a criterion because it is not measurable. It would require correlation of "population distribution at the exact moment of tremor" and "earthquake intensity" to absurd levels of accuracy. I'm confident such correlation data do not exist. Likewise, I doubt reliable mappings of structural damage are available either, certainly not outside the developed world. I recomend that the current criteria (magnitude >=7 or fatalities) are retained as the benchmark. GeoWriter (talk) 20:20, 24 June 2010 (UTC)[reply]

Re:This. Actually that was a valid question back then, I got pinged with it and wrote the article soon after :) ResMar 01:28, 6 August 2010 (UTC)[reply]

Google books throws up multiple references describing Devils Tower National Monument as trachyte including [1][2][3][4]. Although there are just as many, if not more, describing it as phonolite, including all the geology books I looked at. Perhaps you can throw some light on this: has the meaning of trachyte changed over the years, is there some doubt over the classification of Devils Tower, or is it that the common use of the word is more general than the geological definition.? SpinningSpark 06:54, 13 August 2010 (UTC)[reply]

It would seem that the source for all these "trachyte" descriptions trace back to Henry Newton, the geologist with Dodge's 1875 expedition. SpinningSpark 07:04, 13 August 2010 (UTC)[reply]

Thanks for the links to the references. Phonolite was not discovered/defined as a rock type until 1877. If trachyte is being used these days for Devil's Tower, I suspect that it is most likely due to perpetuating outdated sources. Things have moved on considerably in geology in the 135 years since Dodge's expedition. The meaning of trachyte has narrowed as the classification and discovery of new rock types has progressed. Current rock classification standards are summarised in the UNESCO authoritative book on the subject : Le Maitre, R. (editor) (2002) Igneous Rocks: A Classification and Glossary of Terms, Cambridge, Cambridge University Press.

Some igneous rock types are used in a concise/strict as well as a loose/general sense. Basalt is a minefield in this respect, because of its more varied mineralogy and widespread occurrence. As I mentioned in my previous comment, on the Devil's Tower talk page, there is a transition, but Devil's Tower would not be regarded as one of those transitional rock types. Devil's Tower falls into the phonolite category. Incidentally, I recently revised the Bass Rock article the other way, because it is transitional, phonolitic trachyte rather than phonolite. --GeoWriter (talk) 18:39, 14 August 2010 (UTC)[reply]

Sorry for reverting you, I thought you may have been editing based just on what was written in the article but it is now clear that you actually know what Devil's tower is made of. Perpetuating outdated sources may well be right, they all seem to have very similar, even plagiarised, wording and one of them cites verbatim a report from Dodge that sounds awfully familiar if you have read the rest.

Hello there! As part of an effort to determine how many active editors are present in the space-related WikiProjects, some changes have been made to the lists of members of WikiProject Moon (here) and Mars (here). If you still consider yourself to be an active editor either of these projects, it would be appreciated if you would please edit the list so that your name is not struck out - thus a clearer idea of the number of active editors can be determined. Many thanks in advance!

Hi GeoWriter

The journal title is "Carbonates and Evaporites"

Dolomites and calcites aren't evaporites, they aren't water soluble.

Plancton shells snow on the ocean floor.

See rruff.info/ima, choose the tag "Water Soluble" (321 minerals). [5]

I think that you were wrong here. Regards --Chris.urs-o (talk) 12:26, 15 March 2014 (UTC)[reply]

In a lacustrine environment, calcite is the commonest evaporite mineral - also aragonite and dolomite. See [6] & [7]. They may not be mainly evaporitic in their occurrence, but I was taught that they formed part of the Evaporite group. Mikenorton (talk) 14:14, 16 March 2014 (UTC)[reply]

Ok, I'll revert it. --Chris.urs-o (talk) 16:37, 16 March 2014 (UTC)[reply]

Thanks for your comments. I'm glad the issue seems to have been resolved.

All the books I've read about evaporites include calcite and dolomite, although I have noticed that they pay much less attention to the carbonates compared to the halides and sulphates. I think one's view of the "evaporite group" of minerals depends on whether one's focus is initial evaporation or later preservation. The classic descriptions of evaporation focus on the halides and sulphates. Study of the carbonates becomes more important when focus moves to diagenesis and preservation because e.g. calcite is often a pseudomorphic secondary replacement mineral in evaporite rock sequences.

Hi Geowriter, thanks for your help tidying the Tempest Anderson and Trace fossil images I've uploaded to Commons from York Museums Trust's collections. I hope you're finding them interesting! If you feel like making any edits to the related articles and would like some support please let me know, or perhaps you know of other geologically-minded editors I should get in touch with? Cheers!
