@High Seas,
Quote: Can there be any other subject as boring as geology?Certainly most civil engineers find it mind-numbingly dull. It is a subject to get a tick in abox, that's all.
I was away for a few days so I missed some of the "pellets" of wisdom. Im glad that Im not on his xcorrespondence list (other than by his feeble attempts at trying to not sound "special".
PS, Your calcs are probably short, because the MED basin, due to the rotation of Iberia and the Smashing of Apullia into Switzerland resulted in the original shallow basin, deepening as the Med plate, which rose up, began to sink about 30MYa.Ya gotta remember the MEd basin occupies the zone where there was a collision of several landmasses. It involved the collision and rebound of Africa and Europe, and the APulian plate scxhmeared that part of Tethys which kept AFrica and Europe apart. The Med plate was THRUST UP and over surrounding continental landmasses, (witness by several sediment blocks from Pontidean terrains (Turkey),Ionia(or as I like to call "Anea") And Apullian terrains slamming into the Alps (These rocks were all from the Med slab)
The dimensions of the Med were always in a state of transition between desert and submerged terrains. SO, even in fairly recent times 5-30 myA, the dimensions changed by tectonics.
Its not a simple problem of laminar flow. Its hydraulics writ large. AS the basin was infilled, it sank further, and all the landmasses around the margins began to slough as they became supoersaturated.SO we have these huge slides of flysch rock and margina land slides .
The best ways to estimate the basin infilling is to look at the ratios of pollens in the sedimenst as they get incorporated into the ocean bottom. Pollen and forams and radiolarians are really good time indicators. Ive already seen some estimated of basin volumes calulated entirely from foram incorporation and pollen "disappearances" as the ocean levels rose and pollen noi longer fell on the rapidly drowning forlelands.
Its a bit like tree ring analyses, xcept tree rings are a very mature applied science.
