塔里木盆地库车坳陷盐构造特征及形成演化
|
摘要
通过地表地质调查,确定了库车坳陷吐北、克拉苏、却勒和西秋四个不同地区盐构造的变形样式。结合地质和地震资料,建立了不同地区的地震地质结构剖面。应用平衡剖面研究方法,恢复了不同地区的盐构造形成演化历史,并对库车坳陷盐构造的形成机制进行了探讨。
Salt structures widely developed in Kuqa Foreland Basin.However,their deforming styles and developing mechanism are still not clearly known so far.In this paper,we describe the different structure styles from four different places in Kuqa depression by field investigation.They are the salt diapir in Tubei area,the faulted fold in the suprasalt layer in Kelasu area,the thrust sheet in Quele area and the faulted fold in Xiqiu area.On the basis of the outcrop geological data and seismic data,four geological profiles are finished.By the method of balanced cross section,we restore the evolution history of the four different places and probe into the mechanism of salt structures deformation.The results show that the salt structures in Tubei area begin to develop only during the forming of the Jidike Formation,while salt structures in other three places start to develop after depositing of Kuqa Formation.The mechanism of salt structures development in Kuqa foreland basin is a differential load of sediments during mountain-building and compression of South Tianshan area.
