Talk:Stratigraphy

message: Maybe move and merge Archaeological stratigraphy into Stratification (archeology) which basically covers the same content. With a see also link here. -Vsmith 16:25, 15 Nov 2004 (UTC)
replies: text: I strongly disagree.  Archaeologists, in the US, anyway, commonly use the word "stratigraphy" to refer to the process of recording and interpreting strata, as well as using it colloquially as a noun to refer to both the physical phenomena being interpreted and the data resulting from that interpretation Where "stratification" is used, it is more likely to refer to the processes by which soil layers are deposited, and archaeological sites are formed.  I am more inclined to rework portions of the article to make it clear that "stratigraphy" is as key a concept to archaeology as it is to historical geology.  It should be possible to do that without diminishing the value of the article to students of the lithosphere.--Digthepast (talk) 22:08, 27 November 2009 (UTC)
replies: text: Seems to be a sloow discussion - or should I wait five years to respond? Seems things have changed a bit since then, but the archeology bit hardly at all. Vsmith (talk) 22:34, 27 November 2009 (UTC)

message: Similar as in the actual wikipedia article about lithostratigraphy the article fails to define lithostratigraphy correctly. See the definition of the International Stratigraphy Guide:
"A lithostratigraphic unit may consist of sedimentary, or igneous, or metamorphic rocks. Lithostratigraphic units are defined and recognized by observable physical features and not by their inferred age, the time span they represent, inferred geologic history, or manner of formation. The geographic extent of a lithostratigraphic unit is controlled entirely by the continuity and extent of its diagnostic lithologic features." (...) "Lithostratigraphic units are bodies of rocks, bedded or unbedded, that are defined and characterized on the basis of their lithologic properties and their stratigraphic relations. Lithostratigraphic units are the basic units of geologic mapping."
A lithostratigraphic unit needs not to describe stratified rocks, nor do younger rocks need to be structurally above older rocks, nor must the rocks have been laid down horizontally, nor must the rocks be sediments at all.
I would recommend either to include the "lithostratigraphy" article in here (with a correct definition) or to link here to a separate article "lithostratigraphy".

message: I have added 29 possibly useful references mainly on books dealing with stratigraphy. They are sorted by Harvard (Name and Date) order at the end of the article in a section "Proposed References". Please, could you review and use these references by inserting them at the right place in the article. These references are already made with the "Cite book" template (see guideline in: WP:CITET) and will be correctly auto-formatted and also automatically recognised by Zotero (bibliographic extension of Firefox). In advance, many thanks. Shinkolobwe 23:27, 23 October 2007 (UTC)
replies: text: In my opinion, most of these are just various introductory (or advanced) textbooks, and unless something specific is referenced in the text of the article virtually all of them do not belong in the article as references. A few, such as No. 2, No. 25, No. 27, are either too advanced or too specialized to belong here, again unless there is information in them that is used specifically to support something (something specific) in the text. In such a case, citations to page numbers would probably be appropriate. Cheers Geologyguy 00:15, 24 October 2007 (UTC)
