安徽休宁桃溪铅锌矿地质、物化探特征及其找矿潜力
Geological features, geochemical and geophysical anomaly characteristics and prospecting potential of the Taoxi lead zinc deposit in Xiuning, Anhui Province
摘要
Abstract
The Taoxi lead zinc ore deposit is located neighboring the central area of gold polymetallic deposit integrated exploration area of Xiuning-Shexian County in Anhui Province,and it is provided with favorable metallogenic geological conditions.The Taoxi lead zinc ore deposit is controlled by the EW-trending fault with mutiperiodic activity features,and tensional normal fault of the third stage is closely related to the lead-zinc mineralization.The lead-zinc ore deposit was formed by cavity filling through migration of ore fluids into fissure zones,and the orebodies exhibit vein-like form.The geochemical composite anomaly of AP18 obtained by soil geochemical exploration is oval-shaped with EW-trending long axis,and it is controlled by the fault.The geochemical anomaly consists of multielements such as Au,Ag,Cu,Pn and Zn,and its area is 2.6105 km2.The geophysical anomalies of M2 and M3 were detected by high precision magnetic method,and they are consistent with geological features and geochemical anomaly.The results of IP intermediate gradient and IP sounding prove the actual existence of the anomaly,and also reveal the polarization body characteristics in subsurface.Through comprehensive analysis of geological features and geochemical and geophysical characteristics of the Taoxi area,the authors hold that the area has further ore-prospecting potential for polymetallic deposits.关键词
