柴达木盆地早、中、晚侏罗世地层分布的变化较大 ,其沉积中心经历了自西北向北、再向东北的两次大迁移过程。在早侏罗世 ,盆地西北部边缘发育温暖潮湿气候下的断陷河湖沼泽沉积 ,中侏罗世以盆地北部边缘的广盆式断陷河湖沼泽沉积为特征 ,晚侏罗世以盆地东侧的山间凹陷干旱河湖沉积为主。对柴达木微板块西侧的中生代火山岩及与之相邻的塔里木板块、羌塘板块的地磁古纬度的对比分析表明 ,该盆地侏罗系板块之间不同性质的相互作用是控制其沉积 ,并造成其沉积大迁移的主要原因 The distribution of Early, Middle and Late Jurassic strata in the Qaidam Basin changed greatly, and the sedimentary center underwent two large migrations from northwest to north and northeast again. In the Early Jurassic, the margin of the northwestern margin of the basin was developed in rifted rivers and lakes and swamps in the warm and humid climate. The Middle Jurassic was characterized by the deposition of the broad-basin rift rivers and lakes in the northern margin of the basin. In the Late Jurassic, On the eastern side of the mountain depression arid rivers and lakes deposition. A comparative analysis of the paleomagnetic latitudes of the Mesozoic volcanic rocks on the west side of the Qaidam microplate and the adjacent Tarim plate and Qiangtang plate shows that the interaction of different nature of the Jurassic plate in this basin is to control the sedimentation, And cause the main reason for the large migration of sediments
