| 摘 要： | 根据侏罗纪地层分布、沉积特征和构造演化史的综合分析，柴达木盆地侏罗纪经历了两期不同盆地性质的发育和叠加，中侏罗世末期的中燕山运动是盆地性质的转变期。早中侏罗世盆地为南北向伸展构造环境下的断陷型盆地，主要表现为系列小型断陷盆地群，分布在祁连山南侧和阿尔金南缘断裂带附近；晚侏罗世（至白垩纪）为南北向挤压构造环境下的挤压型坳陷盆地，受南祁连山前冲断构造体系控制，其沉积范围明显变大。

| Abstract: | According to comprehensive analysis of Jurassic strata distribution, sedimentary characteristic and tectonic evolution, the Qaidam Basin experienced the development and super imposition of two types of basins during the Jurassic period, the middle Yanshan orogeny at the end of the Middle Jurassic was the transformation time of the basin types. During the Early Middle Jurassic, it was in an extensional tectonic environment and formed a series of minor-scale fault basin group, which was distributed in the south of Qilian Mountain and nearby the southern Altyn fault. During the Late Jurassic and cretaceous, it was in the compressional tectonic setting and formed the down-warped basin, which was controlled by the overthrust tectonic regime in the front of Qilian Mountain, the deposition scope was obviously widening. |
