Prof. Edward Orton, in his Report on the Occurrence of Petroleum, NaturalGas and Asphalt Rock in Western Kentucky, thus clearly states his ideas of theuniversal dissemination and rare accumulations of the bitumens:
"We need to bear in mind that the various members of the bituminousseries are abundantly and almost universally distributed among the unalteredsedimentary rocks of the earth's crust. The valuable accumulations of thesesubstances are rare, it is true, but one can
scarcely go amiss of petroleum, asphalt or gas, at least in small quantities,among the stratified rocks that retain their original
Speaking of the Ohio valley, he adds:
"A fifth of one per cent of petroleum, if distributed through a thousandfeet of rock, would make a total to the acre, or square mile far beyond anyproduction that has ever been realized from the richest oil field, and-percentages of this amount are not only not rare to find, but are even hard tomiss."
Dr. F. W Clarke in his Data of Geochemistry (Bulletin No. 491, U.S.Geological Survey, 1911), discussing these views of Orton with similar views ofT. Sterry Hunt and Szajnocha, says that they "lead to the conviction thatthe formation of bitumens is a general process and by no means exceptional.Wherever sediments are laid down, inclosing either animal or vegetable matter,there bitumens may be produced."
The organic origin of the bitumens, including petroleum, has long been anaccepted fact with nearly all geologists, but the method, place, and time ofthe transformation into petroleum or other bitumen is still underdiscussion.
