Petroliferous Upper Jurassic correlated across W. Siberia, N. Alaska, Arctic Islands

Jurassic deposits are very widespread in the Arctic basin ( Fig. 1 [39,131 bytes] ). The Jurassic is almost entirely represented by terrigenous sediments over this vast territory. It is during the Jurassic when very large sized structural features formed on the West Siberian Plate, the sedimentary cover of which is saturated with oil and gas. These strata are widespread in the Sverdrup basin of Canada and in northern Alaska.
