Organic geochemical analysis of an interbedded shales and sandstone sequence from the Upper Jurassic Hareelv Formation, Jameson Land, East Greenland, has revealed oil shows in the sandstones, consistent with petroleum generation and migration. A comparison of the molecular characteristics of extractable material from the sandstones with those of kerogen and bitumen from the shales indicates that the most likely origin of these shows is generation within the shales with expulsion and short-range migration into the sandstones. This conclusion is based on comparisons of biological marker distributions, stable carbon isotopic compositions of extractable material and kerogen, and pyrolysate compositions of kerogen and asphaltenes. Oil from a seep in the Savoia Halvo region south of Jameson Land can be correlated to the Jurassic sandstone oil shows based on similar isotopic compositions and asphaltene pyrolysate distributions. Impregnation of both sandstones and shales throughout the sequence by products generated at higher maturities is considered unlikely, but cannot be ruled out by the existing data. 18 figs., 6 tabs.
