摘要
通过１：５万区域地质调查工作，基本查明了侏罗系的分布范围及宗别立边界断裂对盆地沉积作用的控制。根据沉积相分析及相区展布特点，首次提出该沉积盆地是一个半地堑式陆相断陷盆地。
By means of 1/50000 negional surveying, it has been established that Zongbieli marginal fault control of thebasin sedimentation and the distribution range of Jurassic System. On the basis of sedimentary factes analysis andthe feature of facies province distribution, we bring on that the sedmentary basin is a semi-graben Fault Basin forthe first time.
