江西九瑞矿集区武山铜硫矿床地质特征新认识及成矿远景分析

Analysis of Geological Features and Ore Perspective for Wushan Copper-Sulfur Deposit in Jiurui Mineralization District

概述了武山铜矿铜硫矿床的基本情况,详述了武山铜矿深部详查结果。深部详查找出了北东东向断裂及岩体内凹处重要的控矿因素和成矿位置,并发现了含细脉浸染状矿化的花岗斑岩、石英斑岩,钾化、硅化蚀变等一系列与斑岩型矿床相关的有利地质现象。关于控矿构造和成岩成矿作用的新认识,对寻找斑岩型矿床以及进一步扩大武山铜矿的资源储量、探究成矿远景、指导找矿方向,具有重要作用。

A brief introduction about Wushan copper-sulfur deposit was provided. And detailed survey by deep drilling revealed the ore-controlling factors and mineralization information about the northeast-east fracture and sunken place in the rock masses,also detected the vein-disseminated granite porphyry and quartz porphyry,and a series of favorable geological phenomena related to porphyry deposits,including potassic and silicified alterations. Those new knowledge about ore-controlling structure and mineralization action is helpful not only to the exploration of porphyry deposit and further expansion of resources reserves of Wushan Copper Mine,but also to investigating metallogenetic prospect and guiding the exploration.
