摘要：
With the recent large hydrocarbon discoveries in the Barents Sea, interest is turning to Triassic shales as the most likely source rocks. The results reveal the relationship between the quality of Triassic source rocks, the amount and type of organic matter, and the environments of deposition. The best source rocks are confined to the Lower and Middle Triassic successions deposited in a deep-water shelf environment in the western part of the basin. Shallow-marine and deltaic argillaceous rocks exhibit fair to poor gas-generative potential. Triassic fluvial-lacustrine deposits have little to no hydrocarbon generative potential.
