对柴达木盆地北缘 (简称柴北缘 )地区的构造型式 ,包括其发育背景、发育的几何扩展方式 ,以及平面、剖面展布特征及其分带性进行了研究 ;对主干逆冲断裂带及其间的逆冲推覆体带、逆冲席带和低应变区的特征进行了详细描述。通过野外观察和室内构造反演来研究推覆构造带的发展演变模式及形成机理 ,指出其逆冲推覆构造带和隐伏逆冲前缘带是最有利的油气勘探目标。
The tectonic patterns of the northern Qaidam basin (including the northern margin of Qaidam Basin), including their developmental background, developmental geometric expansion patterns, distribution characteristics of plane and section, and their zonation were studied. And the characteristics of the thrust belt, thrust belt and low strain zone in the process are described in detail. Through the field observation and in-situ tectonic inversion, the evolution and formation mechanism of the nappe tectonic belt is studied. It is pointed out that the thrust nappe tectonic belt and the buried impulse thrust belt are the most favorable hydrocarbon exploration targets.
