| 摘 要： | 本文通过近年来的地震反射信息研究,对柴达木盆地北缘中、新生代地质构造演化进行了分析,透过红山地区这个窗口,揭示柴达木盆地内中、新生代两个世代的构造成因类型,展示二者叠置关系和构造样式,认为该区存在先张后压的演化历史,且后期挤压作用破坏和改造早期拉张构造样式,从而更有效地指导盆地中生代油气藏的勘探。

| Abstract: | This paper analyses the evolution of the Mesozolc and Cenozoic structures in the northeast margin of Caidam Basin by studying the seismic reflection information. From the window of Hong Shan area, the genesis types of the Mesozoic and Cenozoic structures and the superposition relationship between them could be shown. According to above mentioned, it is thought that the course of extension followed by the compression really existed, and the latter structures related to the compressive stress destoryed the former ones related to the tensile stress. This is of real significance in the further study on the evolution of geological structures and the further exploration of the Mesozoic oil and gas. |
