I wonder if it's even possible?<BR/><BR/>Clastics are a bit easier ... as a prof in a carbonate class I once took said "it's just dirt coming down a hill" ... and he said it with that smirk carbonate geologists have when making fun of clastics. :)Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-5859094080858570248.post-60244430000447626792008-09-14T09:24:00.000+05:302008-09-14T09:24:00.000+05:30Brian- my work on carbonates dealt with diagenetic...Brian- my work on carbonates dealt with diagenetic imprints within 4th and 5th order cycles. The prevailing thinking was that the parasequence (cycle) boundary spanned as you mentioned a much larger time span than the deposit. <BR/><BR/>carbonate production rates are prolific in shallow marine settings and the thinking was that the sediment surface will quickly aggrade and fill up the accomodation space. J.F. Read and R. Goldhammer were spearheading the theoretical work using computer simulations.<BR/><BR/>unfortunately carbonates are going to be much more difficult to handle in experimental basins!! most work is I believe still in computer simulations.<BR/><BR/>thanks for letting me know about AGU<BR/><BR/>cheersSuvrat Kherhttps://www.blogger.com/profile/18281172632784780810noreply@blogger.comtag:blogger.com,1999:blog-5859094080858570248.post-58887985338409452882008-09-14T00:48:00.000+05:302008-09-14T00:48:00.000+05:30Nice post.The "Jurassic Tank" experiments are very...Nice post.<BR/><BR/>The "Jurassic Tank" experiments are very interesting. I don't know if it was from this particular experiment or another from the same tank, but an interesting related to stat to what you talk about above was that the duration of sequence-boundary formation spanned about 3/4 of a full cycle. In other words, not only was it not synchronous ... it wasn't even close.<BR/><BR/>When I attended a field trip w/ Exxon to the Book Cliffs several years ago as a grad student, they claimed that considering a sequence boundary near-synchronous was valid.<BR/><BR/>I'm not saying that one experiment settles that but, as you point out, at least we have a tool to try and test the ideas. <BR/><BR/>I'm chairing a session at the AGU meeting in December about these topics to which the SAFL group has submitted a few abstracts. If you are coming to the meeting, make sure to come by the session.Anonymousnoreply@blogger.com
