Talk:Sequence stratigraphy

Is speculation about Noah appropriate?

"For this reason, most early civilization seaport cities are currently under water (this may be the historic origin of the biblical Noah story)."

The statement MOST early civilization seaport cities need qualifying with examples of such cities.

Also although this may be the origin of the Noah story, it equally may not be. I don’t think the motives behind the writings of early man need to be explored when discussing sequence stratigraphy. —Preceding unsigned comment added by 155.198.91.107 (talk) 13:46, 28 January 2008 (UTC)

Sea level curve

The first figure in this article and the text about it are incorrect. The figure is said to contain a spike in the sealevel curve that represents the last glaciation (Weichsel/Würm/Wisconsin/whatever; from 110.000-10.000 years BP) or (maybe it means) the last ice age (Quarternary, from 2,5 Ma to now). In fact the Neogene is the period from 23 Ma till now, so a spike in the curve during the last 2,5 Ma would hardly be visible in the graph; and certainly not a spike for the last 100.000 years. The text "last glaciation" in the figure is misleading and should be erased. Any misleading statements about the Neogene being the last glaciation should also be corrected in the text.

I believe that the bar is just there to show the magnitude of glacial sea level fall. I clarified. Awickert (talk) 22:25, 15 May 2009 (UTC)

Is the carboniferous "prehistoric"?

Vast amounts of sequence stratigraphic work have been carried out in carbonifrous strata. The carboniferous is not really known as prehistoric. —Preceding unsigned comment added by Russjass (talk • contribs) 12:10, 18 May 2008 (UTC)

Looks like this has been dealt with - I don't see any "Carboniferous" or "prehistoric" here. Awickert (talk) 22:25, 15 May 2009 (UTC)

definitions

I miss the clear definitions of key terms used in the text, e.g. sequence and parasequence; including these right at the beginning would significantly help the reader understand the article. Lumasella (talk) 19:46, 6 January 2011 (UTC)

Diagrams

Diagrams needed for b.sc students to be precise. Kamaleshbarman (talk) 17:10, 1 December 2016 (UTC)

Going around in Cycles

Trying to find a talk post on Stratigraphic cycles, I got all "tide" up. I think some clarification or navigation could help:

• Sequence (geology)
• Stratigraphic cycles, First, Second, Third, ... Seventh order sequences
• Sequence stratigraphy
• Type 1 and type 2 sequence, not to be confused with First and Second order sequences?

Attempted to clarify

Sequence stratigraphy is a fairly technical topic but I tried to reorder some of the material in the introductory section for greater understanding and add just a little more explanatory language for the non-technical audience. Also added references for two recent textbooks on this topic as well as a couple of the classic definitive recent articles. RockDr (talk) 16:48, 18 September 2022 (UTC)
