吉林省地处古亚洲构造域和中朝准地台两个不同的大地构造单元,其构造位置在中国东北占有重要地位。从地质历史发展的观点看,吉林南部从太古宙到中元古代处于地槽阶段,从晚元古代开始转化为准地台阶段;吉林北部从寒武纪开始发展成为地槽,到早二叠世逐渐隆起上升为陆,经过晚二叠世——早三叠世过渡阶段,于早三叠世末发生褶皱造山运动,自晚三叠世开始,与南部准地台一同进入滨太平洋大陆活化阶段。这一总的地质构造背景导
Jilin Province is located in the ancient Asian tectonic domain and the China-North Korea quasi-platform two different tectonic units, and its structure occupies an important position in northeast China. From the point of view of geo-historical development, the southern part of Jilin Province was in the stage of geosyncline from Archean to Mesoproterozoic, from the Late Proterozoic to quasi-platform stage. From the beginning of Cambrian, the northern part of Jilin developed into a geosyncline, After the Late Cretaceous, the Cretaceous orogeny occurred at the end of the Early Triassic. From the Late Triassic, it began to enter the coastal area of the Pacific to be activated along with the southern quasi-platform stage. This general geological structure background guide
