Note: The history does not include Nicolaus Steno, which according to his article and a popular book, was one of the pioneers... 21 Oct 2005, dyuret
I think this statment is not correct! I don't want to modify the article as I'm quite new in WP and not english native-speaker. Please do it for me!
"the Earth's crust is fragmented into tectonic plates that move over a semi-molten upper mantle (asthenosphere)"
SHOULD BE
"the Earth's lithosphere (which is composed by the crust and a part of the upper mantle called LID) is fragmented into tectonic plates that move over the asthenosphere (another part of the upper mantle), which is 5% melted."

Say, I recently wrote Teton Dam, and could use a geology person to use plain English to describe a few details of which I am fuzzy. My fields are math / chemistry, not geology. Any takers? -- user:dino
This page could use some serious expansion. Or should it be merely a gateway to more detailed pages on geology? Is there anyone willing to take a section? I might be able to do some work on History, for instance. Gwimpey 00:10, 10 May 2004 (UTC)
Geology Descriptions
I am a recent masters graduate of Geology and I should like to reply in reference to the request for ideas on how to edit the geology Section. Geology covers many disciplines, which could be used to catagorise this section for you.
They include:-
- Economic Geology
- Geophysics
- Geodynamics, or Structural Geology
- Historical Geology
- Paleaontology
- Petrology
- Geochemistry
- Geological Mapping
- Mineralogy
Each has several sub groups, which should cover the entire subject. I should be glad to edit one or two of the pages if required, as I specialise in Petrology and economic geology, and also dabble in volcanology.

- Hi - don't just ponder, jump right in :). Your expertise is welcome. Note I added a bit of formatting to your message above. This is a great learning experience. I've been playing here for a couple months now. I also recently (in geologic terms) earned a master's in economic geology. -Vsmith 18:14, 9 Oct 2004 (UTC)
Hey, I'm a new commer to the site and I would like to say that I would also be interested in helping out in the definition of geology and all it's aspects. Although I'm not all that experienced, still a first year geology student, I would be glad to help out in any way that I can.
- Hello and welcome - just as Vsmith says to the other newcomer above, just do it! Start visiting geology pages, put them on your watch list, and you can begin reverting vandalism like the rest of us :) -- or add well referenced factual material, or find things that need expansion (see Geology stubs for example) - just remember to not do it out of your head, but to find reliable sources to document your additions. And one little tip - when you add something new, like your recent message here, add it to the bottom with a new header (set off by pairs of = signs) - that's where folks usually look for new messages. And if you sign your message with four tildes, people will begin to recognize you and know that you are User:Geologyboy rather than me, Geologyguy! Cheers! Geologyguy 01:36, 21 January 2007 (UTC)
As a geologist i don't like this defintion of Geology- "Geology is the science and study of the solid matter that constitutes the Earth. Encompassing such things as rocks, soil, and gemstones, geology studies the composition, structure, physical properties, history, and the processes that shape Earth's components". Geology goes far beyond studying the solid matter of the Earth. It would be better to say "Geology is the study of the Earth, its processes and history" and leave it at that. —Preceding unsigned comment added by 213.86.33.33 (talk) 10:13, 8 May 2008 (UTC)
Geography - geology?
Geology differs from Geography in that geology studies Earth without a focus on the human element...
Wow! What a claim. Finding energy and mineral resourses; predicting seismic and volcanologic hazards ... There might be a human element focus involved. I deleted that nonsense. Let's get a better comparison or forget it. -Vsmith 04:45, 24 Oct 2004 (UTC)
remove pedology link
The link to pedology in the geology article should to be renamed soil sciences and removed to the science article under the heading earth sciences. This change is needed to maintain a NPOV, consistent with the International Council for Science which has accepted as equal Scientific Union members the IUSS and the IUGS.
Paleorthid 17:44, 31 Oct 2004 (UTC)
- Hmm... academic semantics and turf wars :-) Put soil science back in and renamed section to Fields or related disciplines. Soil is a bit related to geology, without rocks, minerals, weathering, and erosion, there would be no soil to abuse and fertilize. -Vsmith 00:36, 1 Nov 2004 (UTC)
- That works. Thx for understanding. Semantic/turf deal inevitable. Soils curricula sufficient for a BS in soil science always a challenge to keep in class catalog. Soil Science departments get folded into ag, bio, env, eng, geog or geol depts. Natural to see soilsci as branch of same. Fallout in the not-academic world: state regulations get passed for soilsci practice to require non-soilsci license/reg (Sanitarians, PEs, or RPGs) or certif (crop or ag practitioners). That said, would have been lost mapping soils without my geomorphology class. Geo 60 Mineralogy leveled me tho. ouch. Paleorthid 06:28, 1 Nov 2004 (UTC)
Need a geologist
The Flood geology page is making some very bold and unsubstantiated claims. It would behoove a geologist to go over there and do some heavy editting if your up to the task of taking on the creationists. 67.172.158.8 21:41, 6 Jan 2005 (UTC)
- I went to Flood geology and the talk page and saw a positive and unfolding discussion going on. For instance, creationists admitting that certain theories they had in the past were unsupportable, even within their community. This gets my attention because it speaks to a dynamic that we old-age-earth.ers would typically assume to be incompatible with biblical literalism. And I saw a gallant defense against some of the most damning criticisms one could make of the scientific credentials and sincerity of their supporters within the geologic profession. Look past the dogma, and you see a legitimate tension between uniformitarianianism as a model and our need to understand the effects of catastrophic events. Certainly geologists should visit the Flood geology page and review, contribute, and offer criticism. And look forward to a reasoned response. This free exchange of diverse views between professional scientists can only be good for geology. An invitation to engage in 'heavy editing' suggested by an Anonymous_Coward sounds to me like a call to vandalism, and I hope you will join me in not taking that bait. Paleorthid 21:48, 8 Jan 2005 (UTC)
- Flood geology has gone through a major transition since two months ago and now seems to be ready to actually accept edits from those who know a bit about geology. In particular, it would be nice to have someone to come through and make substantitive critique of the page. We need someone familiar with editting geology articles to help tighten up the article and provide the alternative offered by actual science. Thank you. Joshuaschroeder 06:28, 5 Mar 2005 (UTC)
Sikkim
I need a someone to make sense of the geology subsection in the Sikkim article and see if it is noteworthy. Nichalp 18:10, Feb 13, 2005 (UTC)
New content heeds home
The history of science was getting too long, in mav's estimation. So I am looking for a new home for some of the content. Would it be allright with everyone if I injected some of the content here? Ancheta Wis 19:35, 29 Mar 2005 (UTC)
A new user has just asked me to look over his first article; I've made some comments on the formatting, etc., but it would be good if more expert users could take a look at it. I'm sure that everyone will be gentle... Mel Etitis (Μελ Ετητης) 19:05, 7 Apr 2005 (UTC)
Bunter
Could somebody have a go at starting Bunter (geology), please? Andy Mabbett 08:59, 17 Jun 2005 (UTC)
In the second paragraph of continent granite is described as an example of "metamorphic and sedimentary rock". Can someone check this? -- ran (talk) 17:04, Jun 19, 2005 (UTC)
This now seems to have been fixed - now saying metamorphic and igneous rocks of granitic composition. GB 03:27, 22 January 2007 (UTC)
supernatural?
Hello, there is a content dispute at Methodological naturalism that I've filed an article RFC for [1]
The original question is whether or not the scientific method is a natural method or a supernatural method of scientific investigation. One editor (Markus Schmaus) refuses to allow the scientific method be listed as a natural method unless a link can be provided to support the claim. I assume he is a proponent of Intelligent Design which pushes the view that ID is "scientific" even though it investigates supernatural causes such as how God must have creaeted life on earth. I assume it is this POV that is getting pushed, and Schmaus will not allow the scientific method be listed as an example of MN because then ID would not fit in the scientific method.
In an attempt to resolve the dispute until some sort of consensus was reached, I removed the mention of the Scientific Method as an example of methodolgical naturalism and instead inserted "astronomy, biology, chemistry, geology, and physics" are examples of methodological naturalism. Schmaus is now disputing that these are examples of MN and insists on a URL to prove that they are natural methods rather than supernatural methods of scientific investigation.
Since methodological naturalism is a minor article with only a few editors, the dispute has remained unresolved for lack of any sort of consensus. Please weigh in with your comments at the following links:
Scientific method is natural or supernatural
astronomy, biology, chemistry, geology, and physics are natural or supernatural methods
If you have links to support whether it is supernatural or natural, that would be greatly appreciated. FuelWagon 18:28, 14 September 2005 (UTC)
Principle of Uniformitarianism
Removed the comment:
- Recently many geologists are backing away from this principle in light of evidence of major meteor impacts and results of recent natural disasters.
from the Principle of Uniformitarianism section as it is quite untrue. Geologists recognize that catastrophic events occurring today are a part of the Principle of Uniformitarianism and help explain previously (early 1900s) perplexing problems in Earth history. Vsmith 05:36, 18 December 2005 (UTC)
I certainly agree with removing that comment. Jay Gregg
dablink
I put in a hatnote to cover the journal with the same title. This seems a bit intrusive on a major article, but I can't think of an alternative - I am suspicious that the journal may well be linked to incorrectly as just "Geology". Feel free to revert if you don't think WP:HAT has been satisfied here. TheGrappler 19:21, 27 May 2006 (UTC)
Hard Rock / Soft Rock / Gardening
That's a long list of component topics. Most people in the field divide quite cleanly between the hard rock and the soft rock sides of the business. /Discuss ? A Karley
- So do you mean that the list should just be "Hard Rock" and "Soft Rock"? I feel that most users (who are not "in the field") who come to this page would probably like to see all the subdivisions and click on the links in the list for more info. (Incidentally, I'm among those who are not "cleanly divided" - I work as a geophysicist, indirectly studying the basement igneous and metamorphic rocks, to make inferences about tectonics and structure that have impact on the sedimentary section with the goal of finding oil and gas and minerals). Cheers --Geologyguy 13:15, 13 July 2006 (UTC)
Definition
":Geology (from Greek γη- (ge-, "the earth") and λογος (logos, "word", "reason"))[1] is the science and study of the solid matter of a celestial body, its composition, structure, physical properties, history and the processes that shape it."
I object to the word solid in this definition. It includes the study of all (non-living) matter, solid liquid (as in water) and Gaseous (as in air) and even the study of its Physical properties such as gravity, light and magnetism. unsigned comment by 203.32.87.250
- The definition could be improved. I don't see how the average user, reading the lead to this article would come to the conclusion that geologists study the planet earth, rocks, minerals, and stuff lack that. However, geologists do indeed study water and the atmosphere (hydrogeologists), measure gravity for numerous reasons (geophysicists), and study light (crystallographers and mineralogists), and magnestim (igneous petrologists, historical geologists, stratigraphers). KP Botany 23:07, 23 October 2006 (UTC)
I have just asked a Soil Scientist for his definition of Geology and he claims that some geologists (but maybe its Soil Scientists) now see their ambit of Geology beginning below "weathered rock" (and this could be some 50 meters down) - above this is the province of Soil Science (Categories: Ecology | Land management | Natural resources | Soil science).
Specialization has a lot to answer for by complicating things. Just look at the threads! unsigned comment added by 210.11.233.243
- I think it is now a product of both trends: extreme specialization and collaborations among scientists from different fields. Many geologists also study soils, particularly those who study the ecosystems of various depauperate soils created on specific bedrocks (serpentine soils is one example). I could see a dividing line between "below weathered rock" and above it, although geomorphologists might have an issue with having to concede mass transport of soils to soil scientists. KP Botany 18:11, 26 October 2006 (UTC)
- Soil processes and geologic processes occur simultaneously in the same physical media, especially in that stuff commonly recognized as "earthy materials". Geologists and soil scientists study mass movement of soil from different but overlapping perspectives. Clay mineralogy is equally important to soil science and to geology. Certainly soil science is associated with that portion of earthy material that supports life, but that will not exclude others from studying biogeochemistry. My preference is to include the term lithosphere in the definition of the realm of geology because it is both as comfortably definable conceptually as it is ambiguous in application. Any definition must leave ample room to encompass a connection to biogeochemistry, weathering, erosion, material transfer, energy transfer, and any number of other aspects always considered fundamental to geology. The lithosphere/pedosphere distinction is workable from a soil scientist's perspective. We soil scientists have a saying: "Water is just dilute soil". It is absolutely true from our perspective, but it is not an encyclopedic observation. Similarly, all planetary solids are not geologic materials from an encyclopedic perspective. -- Paleorthid 20:59, 26 October 2006 (UTC)
catastrophism - Geologists accepting more creationist ideas
I believe it can be readily shown that geologist are accepting more of the ideas asssociated with creationist geology (namely the doctrine of catastrophism). I believe this should be noted in the article. 136.183.154.18 04:09, 29 November 2006 (UTC)
- This fundamentally ignores what catasrophism and uniformitism actually mean: The processes that maintain our planet's surface over the aeons. The concept that meteors striking the earth, massive, widespread volcanic eruptions, etc. shaped the earth, even though they are not seen today are the basis of modern catasrophism. This is not tacit support for some concept of global flood, even if creationists call it the same thing. It is the admission that some forces not seen today, such as meteor strikes, planetary collision (creation of the moon), and so on have happened in the past four billion years. Adam Cuerden talk 08:15, 29 November 2006 (UTC)
...And "creationist geology" has, of course, been disproved. This is banned user "kdbuffalo" attempting to evade his ban. This address has now been blocked, but he may use others. --Robert Stevens 09:37, 29 November 2006 (UTC)
- Doesn't matter if it is disproved or not, the "creationist geologist" and other nonscientific earth scientists can have their own pages should they be required. No room or reason for young earths and young gods here. KP Botany 03:39, 30 November 2006 (UTC)

Add importance of Geology
My basic worry is that the importance of geology is not entailed in this Article especially in relation to civil engineering since they work hand in hand. —Preceding unsigned comment added by 212.85.201.250 (talk) 22:05, 5 September 2007 (UTC)
- I agree with this, the article as it stands gives the impression of geology as a purely academic/philosophical pursuit. The everyday importance of engineering and environmental geology should be mentioned at least briefly.J.S.Salonen (talk) 11:10, 10 April 2008 (UTC)
- I've added a sentence to the lead that hopefully addresses to some degree the lack of weight given to the applied side of the science. Mikenorton (talk) 18:13, 27 June 2008 (UTC)
Geo means Earth
I am interested in advancing science through linguistic accuracy. Under the heading "Geology", there is a section called "Planetary Geology". The only planet that has geology is Earth. When referring to the structure and processes of other planets the terminology should be "Planetary Morphology" or "Planetary Tectonics". The problem with this kind of linguistic inaccuracy is that it skews our perception of the world by constantly seeing the universe through a Geo-centric and Anthropocentric lens. Our knowledge will advance much more quickly when we start with the assumption of similarity rather than difference. The universe does not follow the example of Earth. Earth is an example of the patterns and processes that guide the transformation of everything.Dmguthrie (talk) 16:25, 13 June 2008 (UTC)
- You might want to have a look over at Areology and this talkpage discussion. Cheers, --Plumbago (talk) 16:42, 13 June 2008 (UTC)
The phrase "physical geology" is used repetitively in geology related articles[3] (ca 60 hits, some talk pages), but seems nowhere to be defined. IMHO, this and the History of geology article need do so, preferentially, as a section title one can link using {{R to section}} on a redirect. I've also a sneaking suspicion, t'would be a good sub-category of Geology and help disburse the long list of sub-cats in a better organized manner. // FrankB 18:07, 26 June 2008 (UTC)
- Seems physical geology is simply the name of the first or introductory college class in geology. It was back when I started (1968) and doing a simple google search seems to say that's still the case. The second course was historical geology which introduced paleontology and the history of life and earth. The geology curriculuum then bifurcated into physical (mineralogy, petrology, structural, etc) and non-physical or paleontology with related bridge topics of stratigraphy and sedimentology. So, what is physical geology? - anything geological that isn't paleontology based(?). And physical geology would be a redirect to geology (which I'll do now). If anyone thinks physical geology could be a stand-alone article, then do it. Vsmith (talk) 23:14, 26 June 2008 (UTC)
If there is a definition (like "the name of the first or introductory college class in geology"), it could become a sentence in the present article. Otherwise, a redirect is fine.--FocalPoint (talk) 11:20, 25 January 2009 (UTC)
- Maybe a soft redirect would be better, with physical geology described like that in a sentence, and then the user could go over to the main article on geology? Awickert (talk) 18:44, 25 January 2009 (UTC)
Major edits: discuss
I just made a series of major edits to the geology article (the science part; I left the history part as it was). I think that they make the article flow better, but please send me a message/discuss to tell me what you think if you have a strong opinion. Most of what I did was move a large amount of the muddle at the top to a section on modern geology at the bottom, and made the introduction to the article shorter and (hopefully) more approachable. The article still definitely needs a decent amount of work. Awickert (talk) 16:51, 27 September 2008 (UTC)
Based on the discussion at Wikipedia:WikiProject_Geology, I created a page in my sandbox to start writing up the methods of geology: User:Awickert/Sandbox/Methods_of_geology. In particular, we would cover the classic approaches that one would need for field geology and mapping: structure, sed/strat, and petrology. The goal is that this would become a method-based instead of discipline-based introduction to classic geological investigation, and would link back to the main pages on each of the disciplines involved. Please assist if you have time and interest! Awickert (talk) 19:24, 25 January 2009 (UTC)
- I just added a big fat new chunk with the whole methods section. Please undo and comment if you don't like it, or edit it. Awickert (talk) 22:48, 30 January 2009 (UTC)
Is this useful anywhere? "Natural Cannonballs" - Popular Science 1916
Could an expert take a look at this magazine article and see if it is worth including in Wikipedia somewhere?
The cannon balls illustrated are simply big, nearly spherical rocks which are found at intervals in the soft sandstone of Southern California, the same sand formation in which great deposits of petroleum are found... (with a picture)
This might be notable but I don't know where. The article is printed in the USA before 1923 so the image is public domain and can be used in Wikipedia. -- DMahalko (talk) 00:54, 1 March 2009 (UTC)
Suggested Reorganization: Geologic Time
I suggest to reorganize the portions of the article on geochron, "important methods in the development", and the time-scale into a single big section on geologic time. This new section would talk about (with links to main articles):
- The age of the Earth
- Geologic time-scale
- Relative and absolute dating: radioisotopes, correlating section, fossils
- Field methods for relative dating (all of the "important methods in the development")
Any thoughts? I'll give it a day or so and then start moving stuff around. Awickert (talk) 21:50, 13 March 2009 (UTC)
- Well, here goes... Awickert (talk) 01:31, 15 March 2009 (UTC)
- On second thought, this is too big of a splice... I'm putting it together at User:Awickert/Sandbox/Geology. Awickert (talk) 01:45, 15 March 2009 (UTC)
Survey
How do other editors think that this article should be organized?
A) Like it is now
B) With sections "Whole-Earth structure", "Methods of Geology", "Planetary Geology", and "Applied geology", merged into one section organized by geologic topic/discipline
C) The same as above, with "Geologic time" taken out of its current placed and placed in the organization as a geochronology discipline?
Awickert (talk) 01:48, 10 May 2009 (UTC)
Sedimentology
The following section was in a part of the article that didn't make sense. Perhaps it would make sense to restructure by discipline?
- "
- Sedimentology is the study of sediments and the study of the processes that created them. The complete cycle is composed of: weathering, erosion, transportation, deposition, diagenesis and lithification.
- Weathering, is the decomposition or hard rock, either physically or chemically, into dirt or sediment.
- Erosion, moving of loose sediment from one location to another.
- Transportation, is the bulk movement of sediment by water. Transportation begins when the sediment initiates movement till it ends in the bay."
