摘要

It is generally thought that the Lower-Middle Jurassic is the major source rock in the northern Qaidam Basin, of which the seventh member of the Dameigou Formation is a high-quality source rock. Aiming at further evaluating the hydrocarbon-generative potential of the Lower-Middle Jurassic in the east part of the northern Qaidam Basin, the present study systematically sampled mudstones, oil shales, black mudstones and coals from the Lower-Middle Jurassic Dameigou Formation and performed conventional geochemical analyses. The results showed that the hydrocarbon-generative potential of the first member of the Dameigou Formation was as good as that of the seventh member, which was the first positive recognition on source rocks of the first member of the Dameigou Formation in the northern Qaidam Basin.
