广东元湾金多金属矿床成矿地质特征及找矿潜力浅析

Metallogenic geological characteristics and prospecting potential of yuanwan gold polymetallic deposit,Guangdong Province

北市元湾地处粤西隆起的北东缘,广宁-罗定断裂变质带的北东段、河台金矿田[1]的北东部。区内构造活动、岩浆活动较为活跃,金矿(化)体受断裂破碎带及带内的糜棱岩带直接控制,金矿体主要发育在炭质泥岩、含炭泥质粉砂岩等软弱层位地区。本文论述了区域地质背景、矿体地质特征,分析了矿床成因,并对找矿潜力地段做了评价。

Yuanwan of Beishi is located in the northeast margin of the western Guangdong uplift,the Northeast segment of Guangning Luoding fault metamorphic belt and the northeast of Hetai gold field.Tectonic and magmatic activities are relatively active in the area.The gold ore (mineralized) body is directly controlled by the fault fracture zone and the mylonite zone in the zone.The gold ore body is mainly developed in the areas of carbonaceous mudstone,carbonaceous argillaceous siltstone and other weak layers.This paper discusses the regional geological background,geological characteristics of ore body,analyzes the genesis of the deposit,and evaluates the prospecting potential area.
