| 摘 要： | 通过综合研究相山铀矿田北部矿床勘探资料,加深了对赣中相山铀矿田逆冲推覆构造认识。相山铀矿田逆冲推覆构造总体呈EW向展布,推覆运动方向是从南往北。构造主滑脱面发生于震旦系基底变质岩层(Z)与上侏罗世打鼓顶组下段(J3d1)岩层之间,将震旦系基底变质岩逆掩于上侏罗统打鼓顶组下段砂岩、砂砾岩之上。推覆构造系统由前缘断层、反冲断层、主滑脱带(主干构造)、推覆体和构造窗组成。推覆移动距离达3～4.5 km。推覆构造主要形成时代为晚侏罗纪,即燕山晚期。

| Abstract: | Through the comprehensive study on the exploration data of the deposits in the northern part of Xiangshan uranium ore field,the overthrust structure is recognized deeply.The overthrust structure strikes EW on the whole and the direction of movement is from south to north.The main detachment surface occurred between Sinian(Z) metamorphic rocks and Jurassic(J3d1)layers.Sinian metamorphic basement is overthrust on the top of Lower Daguding member of Upper Jurassic Group.The nappe system consists of front fault... |
