摘要
赣东北多期造山带发育一种双层复合逆冲推覆构造，它是由下部的登山—横峰逆冲断层系和上部的葛源逆冲推覆构造共同构成。地质年代学及运动学研究表明，登山—横峰逆冲断层系形成于加里东期，自南东向北西运移达３０ｋｍ以上，应变速率ε＝２．４×１０－１２／ｓ。葛源逆冲推覆构造则形成于印支期，自北西向南东运移至少５０ｋｍ。
The two layer complex thrust nappe tectonic developed in the multiphase orogenic belts in northeastern Jiangxi.Thrust nappe tectonic belt consists of upper Geyuan Thrust nappe and lower Dengshan Hengfeng thrust system.The research of geochronology and kinematics indicates that Dengshan Hengfeng thrust system formed in Caledonian and slided from SE to NW,the distance of movement exceeds 30 km,strain rate ( ε ) is 2.4×10 -12 /s.And Geyuan thrust nappe thrust formed in Indosinan and slided from NW to SE,the distance of movement is 50 km at least.
