摘要
在桐柏-大别碰撞造山带南部,随县—枣阳地区的板桥—耿集剖面上发育着十分典型的构造窗和飞来峰构造。构造窗出露的是扬子型震旦纪—早古生代未变质的沉积盖层。飞来峰则由传统上称作应山群的变质岩系构成。板桥—耿集“峰”、“窗”构造的确立揭示着桐柏-大别碰撞造山带南部随县—枣区大规模推覆构造的存在,并为解决该地区地层划分、对比中存在的问题以及探讨造山带前陆带形成历史提供了有益的启示和信息。
There are typical klippen and tectonic windows on Banqiao-Gengji section in the south part of Tongbai-Dabie orogenic belt. The outcrops in the tectonic windows are sedimentary cover on Yangtze Plateform with the Sinian to Lower Palaeozoic ages. And the klippen are consisted of the metamorphic rocks which were formerly called Yingshan Group and proved to be a set of Sinian and Lower Palaeozoic metamorphosed sedimentary cover. The klippen and tectonic windows on Banqiao-Gengji section are a good evidence for the existence of large-scale overthrust structures in Tongbai-Dabie orogenic belt.It is a typical section for study of the tectonic framework and evolution of this orogenic belt.
