| Abstract: | With complex structure of strata and variation of lithology, the Jurassic System of Jiangping Basin is a set of deposition of inland fluvial and lacustrine facies, and can be divided into three groups of strata sequences. Its changes show the law of sedimentation changes in the time of from spreading to contraction of Jiangping Basin in Middle Jurassic, the change process of sedimentation system domain, and the sedimentary characteristics of rich sources of materials, shallow lake and rapid variation of facies. Compared with those of continental marginal basin facies, the characteristics of strata and system domain of its strata sequences are different. |
