Genus and 40 species of Jurassic Pteriomorphia and Isofilibranchia from Northern Tibet were described in present paper. The data of genus and species of Jurassic Pteriomorphia and Isofilibranchia from Northern Tibet, Southern Tibet, and India were studied with cluster analysis respectively. The Jurassic palaeobiogeographic and palaeogeographic relations of these three regions were also discussed on the basis of the result of cluster analysis and analysis of the controlling factors of bivalve distribution.

The lithofacies and paleogeography mapping based on high resolution sequence analysis show the sandbody distribution clearly. The paleoshoreline in this area is defined by paleosalinity recovery. Deltaic front subfacies mainly developed in the study area, with small-scale of deltaic plain in northeast.

基于高分辨率层序地层学分析的岩相古地理编图结果非常清晰地显示了研究区长6段砂体展布特征，同时通过古盐度恢复，首次确定了该区湖岸线的位置，从而确定研究区主要发育三角洲前缘亚相，三角洲平原只在东北一隅有小范围分布。

Based on paleogeography, paleotectonic condition, rock composition, structure and tectonics, as well as development and distribution feature of sand body, the authors believe that the sedimentary environment of Dalinghe reservoir is mainly gentle slope-type sublacustrine fan middle fan subphase with supplying waterway, which is composed of braided channel, braided interchannel, middle fan front microfacies.
