摘要:

在研究我国东部乃至东亚濒太平洋地区的地质构造特点时,规模宏伟的呈北北东方向延展的三对复式隆起、沉降折带格外引人注目。李四光教授依据地质力学理论,从构造体系观点出发,将其命名为新华夏构造体系,即新华夏系。并从这一巨型构造体系成生发展特点的研究中,予见到其中的三个巨型沉降带是十分优越的含油气远景区。

Abstract:

On the basis of the shifts of continental margin since Mesozoic time and the patterns of stress action during tectonic movements in the areas of the east China and the eastern Asia as a whole,it is suggested that the Neoca-thaysian Systems were generated after Whaiyang movement which took placeat the ead of middle Triassic,and now these Systems occupy a broad terri-tory.east of the north-south tectonic structures,extending from Mt.Helan through Mt.Longmen to central Yunnan.Properties in stages of generation and development of Neocathaysian Sys-tems,principles of their division and controls of oil and gas are the primarypoints required to be discussed in this study.According to data on sedimentation,structures and tectonic movements,the process of development of the Neocathaysian Systems can be divided into three stages,namely:①La-te Trissic-Jurassic,②Cretaceous-Paleogene,and ③Neogene-Quarternary.For the purpose of petroleum geology,it is considered to be necessaryto distinguish the primary sedimentary basins from the later ones in orderto have a good knowledge of the process of generation of different subsidence regions and it is emphasized that of prime importance are controls occur redunder a variety of conditions,such as ordinal or seguencial controls by various degree of tectonic structures,composite controls by the same tectionic stru-ctures aud composite controls by different tectonic structures.Finally,thebasic features of oil and gas controls by stages of Neocathaysian Systems arealso discussed thereafter.
