一、引言本文讨论范围包括贺兰山、六盘山、龙门山和大雪山一线以东的广大东北、华北和华南地区及台湾省(简称中国东部)。中国东部自前震旦纪结晶基底形成后(其中华南东部是加里东褶皱基底),古生代时期受地中海构造体系和西太平洋构造体系的控制,主要处于一个三面有地槽带围限、内部为地台的发展阶段。随着属于地中海构造体系的天山和蒙古-大兴安岭地槽带、昆仑山-秦岭地槽带和川西-滇西地槽带于古生代至三迭纪期间逐渐褶皱迴返结束地槽生命后,中国东部受西太平洋构造体系的影响便相应地明显起来,成为中国东部中新生代地质构造发展的主导因素。
I. INTRODUCTION This paper covers the vast areas of northeast, north and south China and the province of Taiwan to the east of Helan Mountain, Liupan Mountain, Longmen Mountain and Daxueshan Mountain (eastern China). After the formation of the pre-Sinian crystalline basement in the eastern China (where the eastern South China is the Gallifer fold basement), the Paleozoic was dominated by the Mediterranean and Western Pacific tectonics, and was mainly surrounded by a trough of three sides and an inner platform The development stage. With the Tianshan Mountains and the Mongolia-Daxinganling Trough Belonging to the Mediterranean Tectonic System, the Kunlun Mountains-Qinling Gully Belt and the Western Sichuan-Western Yunnan Gully Belt gradually folded back during the Paleozoic to Triassic Period and ended their life. The influence of the western Pacific tectonic system is correspondingly clear and becomes the dominant factor in the development of the Meso-Cenozoic geological structure in eastern China.
