安徽省绩溪县逍遥钨矿地质特征及矿床成因分析

Geological characteristics and genesis of Xiaoyao tungsten deposit in Jixi County, Anhui Province

本文通过对安徽省绩溪县逍遥钨矿地质条件进行分析,对矿床成因进行了总结.安徽省绩溪县逍遥钨矿赋存于兰田组三段地层中,其成因为是地层、岩性和岩体的侵入作用等因素综合作用的结果,成矿物质来源于岩浆,同时具有壳源物质的混染,矿体围岩主要为矽卡岩、角岩(角岩化板岩)、花岗闪长岩,逍遥矿区的断裂构造、岩浆侵入接触带构造及褶皱构造都是形成矿床的有利条件.

Based on the analysis of geological conditions of Xiaoyao Tungsten Mine in Jixi County,Anhui Province,the genesis of the deposit is summarized.The Xiaoyao tungsten deposit in Jixi County,Anhui Province occurs in the third member of the Lantian Formation.Its genesis is the result of the comprehensive action of strata,lithology and intrusion of rock mass.The ore-forming materials are derived from magma and contaminated by crust-derived materials.The surrounding rocks of the ore body are mainly skarn,hornblende(hornblended slate)and granodiorite.Fault structure,magmatic intrusive contact zone structure and fold structure in Xiaoyao mining area are favorable conditions for the formation of ore deposits.
