安徽巢湖一带的多层次推覆构造

POLYLEVEL NAPPE STRUCTURES IN CHAOHU, ANHUI PROVINCE

摘要: 通过1:5万区调工作,在巢湖一带发现了多层次推覆构造。木文结合区域地质情况,对多层次推覆构造及形成的主要条件等作一介绍。

Abstract: Polylevel nappe structures have been recognized in the Chaohu area, Anhui Province, according to a study, analysis and comparison of a large amount of sedimentological, paleontological, geophysical and geochemical data. Based on the overlapping relationship, they may be divided into three sheets: the upper nappe, middle nappe （Yinping allochthon） and lower nappe. Analyses of tectonic environments and stratigraphy indicate that these nappes resulted from lateral compression and gravity gliding.
