闽北仁寿地区逆冲推覆构造

Thrust Nappe Structures in the Renshou Area of Northern Fujian Province

逆冲推覆构造发育于闽北变质岩中 ,由一系列规模不等向南东倾的叠瓦状逆冲推覆断层及其上盘的推覆岩席组成 ,由南东向北西方向推覆 ,往逆冲方向可分为上、下 2个逆冲推覆构造系 ,是前展式逆冲推覆构造 ,作用时期发生于印支期—燕山期。

The thrust nappe structures, well developed in the metamorphic rocks of Northern Fujian, are made up of the different scales of the east tilting imbricate thrust nappe faults and the nappe sheets of their upthrown sides. The nappe direction is from southeast to northwest. The thrust nappe structures in the surveyed area belong to an advancing thrust nappe structure, and can be divided into the upper and lower thrust nappe structure systems along their thrusting direction, the active time of which is the Indosinian and Yanshanian epoches.
