摘要
采用现代构造几何分析方法 ,研究了巢湖煤田的控煤构造 ,发现巢湖煤田主要受大型平卧式褶皱逆冲推覆构造控制。按构造变形特点从南到北可以划分为和县 -含山平卧式褶皱推覆构造、巢湖银屏山平卧式褶皱推覆构造和无为平卧式褶皱推覆构造 3个构造带 ,卷入了震旦系灯影组—三叠系的整个扬子海相沉积盖层。
Based on the modern tectonic geometry theory, it is studied that the mine controlling structural styles of the Chaohu coalfield, eastern Anhui Province. It is found that the Chaohu coalfield is dominated by large scale recumbent fold thrust system. Based on the tectonic properties the system can be separated to 3 tectonic zones, including Hexian Hanshan recumbent fold thrust zone, Chaohu Yingpingshan recumbent fold thrust, which involves the entire Sinian Triassic passive continental cover deposits of the South China block. It is proposed that the recumbent fold thrust system of the Chaohu coalfield was a result of the Yangzi plant along the Tanlu fault zone thrust in A type to North China plant during early Mesozoic time.
