Possible origin of Saudi Arabia's Ghawar supergiant oil field
Almost every literate person knows the basics of oil. Almost every literate person also knows something about plate tectonics. While coupling of these two topics has been the focus of many studies, all to date has mostly remained indirect.
In a thought-provoking and already controversial paper, authors Giovanni Muttoni and Dennis Kent suggest direct links between major oil provinces and tectonics.
The concept lies in polar wander and relatively rapid past movements of continents with respect to latitude.
At a basic level, and at certain locations, massive amounts organic carbon could have been emplaced at equatorial latitudes and subsequently capped with sediments deposited at sub-tropical latitudes.
Time will tell whether the idea is right, but the paper nonetheless forces the scientific community to think.
