摘要
通过对河北赤城于家沟逆冲推覆构造的深入研究,作者提出了岩浆岩地区逆冲推覆构造发育的基本模式。其主滑面表现为上缓下陡,深部与邻近的基底大断裂交汇合一。野外判定岩浆岩地区逆冲推覆构造的主要标志是逆冲叠瓦扇和软弱滑动层的存在。
Authors suggest a basic pattern of the thrust-nappe structure in magmati c body areea through studying the Yujiagou thrust-nappe structure in Chicheng, He-bei province. It is gentle in upper part and steep in lower part of the thrust, which is rooted in the basement fault. The imbricate fan of thrusts and soft layer are main structure features distinguishing thrust-nappe structure in magma-tic body area.
