安徽脉石英矿地质特征及成矿规律探讨

Geological Characteristics and Metallogenic Regularity of Vein Quartz Deposit in Anhui Province

安徽省内脉石英矿床类型主要为岩浆热液型和变质热液型。断裂构造与脉石英矿的形成关系密切,为矿体形成提供了良好的运移通道和成矿空间,富含硅的岩浆热液、变质热液沿构造裂隙运移并充填其中,形成脉石英矿。本文初步探讨了安徽省内脉石英矿地质特征及成因类型,总结了成矿规律。根据分布空间位置,结合省内成矿区带划分方案,初步将安徽脉石英矿划分为3个成矿区:青阳—休宁成矿区(Ⅰ区)、大别山东段成矿区(Ⅱ区)、蚌埠—五河成矿区(Ⅲ区),为今后安徽脉石英找矿勘查部署提供了参考。

The main types of quartz deposits in Anhui province are magmatic hydrothermal and metamorphic hydrothermal types.Fault structures are closely related to the formation of vein quartz deposits,providing a good migration pathway and ore-forming space for the formation of ore bodies.Silicon rich magmatic and metamorphic hydrothermal fluids migrate and fill along structural fractures,forming vein quartz deposits.This article preliminarily explores the geological characteristics and genetic types of vein quartz deposits in Anhui province,and summarizes the ore-forming laws.Based on the distribution space and location,combined with the division plan of the province's mineralization zone,the Anhui vein quartz deposit is preliminarily divided into three mineralization zones:the Qingyang Xiuning mineralization area(Zone I),the Dabie mountains mineralization area(Zone II),and the Bengbu Wuhe mineralization area(Zone III)provide reference for future exploration and deployment of quartz vein in Anhui.
