摘要
歙县西坑-大谷运地区位于扬子板块东南部,燕山晚期旌德复式岩体与晋宁期许村岩体之间。区域性北东向的许村-旌德大断裂和近东西向汪满田韧性断裂变形带交汇处。区内地质构造复杂,经历了多期次构造活动,成矿地质条件优越,航磁异常突出,1∶5万水系沉积物测量显示有1个面积达34.8km2的Bi、As、Cu、Pb、W、Mo、Ag、Au等元素的综合异常,具较好的找矿潜力。本文重点从物化探异常特征来探讨该地区的找矿方向。
The Xikeng-Daguyun area, She County lies in southeastern part of the Yangtze plate, between the late Yanshanian Jingde composite rock body and Jingning period Xucun rock body, the meeting place of regional NE-trending Xucun-Jingde major fault and almost EW-trending Wangmantian ductile fractural deformation belt. In the area, geological structures are complicated and have experienced multi-phase structural activities, metallogenic geological conditions are superior, aeromagnetic anomalies are outstanding, 1：50000 stream sediment survey indicates an area of up to 34.8 km2 with integrated anomaly of Bi, As, Cu, Pb, W, Mo, Ag and Au and good potential for ore prospecting. This paper focused on ore-prospecting direction in the area in view of geophysical and geochemical features.
