A direct dependence is established between the scale of accumulation of oil source organic matter and the average annual temperature, illumination and supply of biogenic elements to the photic layer of the water mass in a sedimentation basin. Other conditions being favourable, the oil-generating potentials of sedimentary-rock basins depend upon their paleolatitudinal position during accumulation of oil-source deposits. Oil and gas contents are predicted for the shelf zones of other marginal Arctic seas in Russia.
