[edit] Oil in Prudhoe Bay
What conditions lead to the formation of so much oil in an area this far north? Was this area previously south and drifted north over 10's of thousands of years? Or was the climate so much warmer this area supported lush plant growth at some point in time?
- All of the above, to some extent. The source rocks are of three ages - Triassic, Jurassic, and Cretaceous. Although this part of Alaska was not particularly far south at those times, the climate was indeed significantly more uniform and warmer worldwide then (65 to 250 million years ago). Dinosaur fossils and trackways exist in the Cretaceous of the North Slope. --Geologyguy 16:40, 7 September 2006 (UTC)
