Small-scale petroliferous basins in China: Characteristics and hydrocarbon occurrence

A large number of small-scale lacustrine sedimentary basins are widely distributed across China. Studies of such basins have been limited. These basins have complex characteristics and thus exhibit significant differences in terms of their hydrocarbon potential. At present, among the known 348 small-scale basins with areas less than 20,000 km2 ( 200 m/m.y. [>656 ft/m.y.]) during deposition of the source rocks within underfilled and...
