笔者运用 1 ∶ 5 万双柳树幅、白雀园幅区域地质调查成果，阐述商城石门冲一带发育的逆冲推覆构造。大别山商城石门冲一带中生代逆冲推覆作用，使本区发育的中—新元古界龟山岩组、下古生界石门冲岩组、上古生界石炭系及中生界朱集组等，不同程度卷入 NE 向逆冲推覆系统中，形成一系列构造窗、飞来峰和叠瓦状逆冲断层带。逆冲推覆距离最小约为 6 km，形成时代约为中侏罗世—晚侏罗世之间，最晚不超过早白垩世。

Using the achivement of 1∶ 50 000 regional geological surveying work of“Shuangliushu sheet”and “Baiqueyuan sheet” ，the authors report the structure of thrust nappe in Shimenchong area of Shangcheng in Dabie Mountain． The tectonic role of Mesozoic thrust nappe in this area made the Mesoproterozoic- Neoproterozoic Guis- hang Formation，Lower Palaeozoic Shimenchong Formation，Upper Paleozoic Carboniferous，and Mesozoic Zhuji Formation，all involved in the NE direction thrust nappe structures，and developed a number of tectonic window， klippe and thrust zone in imbricate- shape． The thrust nappe distance was about 6 km in minimum． The thrust nappe formed between Middle Jurassic and Late Jurassic in age，the latest time is not over the Early Cretaceous．
