More on ocean trenches and their relation to biotic formation of oil:
"... The Tethyan Trench extended at its greatest during Late Cretaceous to Paleocene, from what is now Greece to the Western Pacific Ocean. Subduction at the Tethyan Trench probably caused the continents Africa and India to move towards Eurasia, which resulted in the opening of Indian Ocean. When the Arabian and Indian plates collided with Eurasia, the Tethys Ocean and the trench closed.
Remnants of the Tethyan Trench can still be found today in Southeastern Europe and southwest of Southeast Asia. ..."

It is highly probable that the oil of the Middle East comes from the creatures (algee included) that lived in the now non-existant Tethyan Ocean more than 200 million years ago. - Note the location of the Tethyan Trench went thru Iraq and Iran in the arc from Greece to westen Pacific, but the deepest part, where most biologic sedements were deposited and where firm evidence of it still exist, was the central section (Now called Iraq and Iran). Also why China is finding oil in it western province and now building a 1700 km large diameter pipeline to exploit it. (Part of reason China is consumming about 2/3 of all the steel the world is now producing!) Western oil companies have suppected for decades that this region of China would be very oil rich, but did not try to even explore it for three main reasons:
(1) It is very rough moutainous terrain (northen side of the Hymalayian mountains) - Same geology*, a continuation of those mountains into NE Iran and Afganistan, as where Iran's oil and gas is. (Possibly Afganastan also has oil in its NE mountains - that may explain at least part of why US is fighting there.)
(2) China owns it - not known to be friendly to western oil companies.
(3) Pipeline required to get it to Ocean for export is too long, expensive, and must pass thru equally unfriendly countries (and the Moslem "war lords" ruling the region as in Afganistan's & Iran's NE mountains) if going to the Persian Gulf.
Someday, China may not only be self-sufficent in oil, but a significant exporter. The oil of Burma**, which is keeping that badly mis managed country economically sound despite buying large quantities of militray supplies from China, is probably the eastern most end of the big oil band China will soon be tapping. All thanks to those marine creature who died more than 200 million years ago!
-------------------
*The african and Indian tectonic plates collided with the Eurasian plate and threw up this large mountain chain as they subducted under the Eurasian plate. The subduction was sloping downward so as to favor oil flow into the western side, but as it no doubt was highly fractured China will have a lot too, perhaps even more as the Eurasian plate may provide better traps as was less destroyed in the collision. (Did not subduct, but rose on the western side to become these mountains. -I am not a geologist, but that is my understanding. - Perhaps someone can amplify or correct as needed?)
**As an illustration, not that any more are needed, as to how much big oil controls the US behind the scenes with GWB as "FRONT MAN" note that even the new "tougher" sanctions against Burma being proposed by US to UN Exclude any interence with the purchase of oil from the generals ruling Burma! (India imports this oil from Burma so is also opposed to stopping its flow. I think I read that India is even now still building a new pipeline to Burma for its transport! I am sure that India is working on reopening WWII's "Burma road," as I made a new thread about that last year.)
