摘　　要：南冲铜钨钼矿位于赣东北地区。本文对其矿床地质特征、矿体特征及矿石特征等进行详细调查与分析,南冲钨钼矿床分为西坑坞(Ⅱ号)和王坊(Ⅰ号)两个矿化带。根据铜、钨、钼矿化特征可进一步划分为铜(钨)矿化带和钼矿化带。铜(钨)矿化带与矽卡岩带一致,而钼矿化带则与主岩体的内外接触带密切相关,两者部分重叠。矿石类型为矽卡岩铜(钨、钼)矿石,细脉浸染状斑岩辉钼矿矿石和细脉状角岩辉钼矿矿石三类。矿区范围内有矽卡岩、蚀变斑岩、蚀变围岩三种不同蚀变岩类。通过分析得出,南冲铜钨钼矿床成因类型应为斑岩型钼矿床和矽卡岩型铜钨矿床两位一体的复合矿床,是一特定矿床组合。The Nanchong copper tungsten molybdenum deposit is located in northeastern Jiangxi Province.In this paper,we detailed investigation and analyzed the ore deposit geological features,ore body characteristics and ore characteristics,the Nanchong copper tungsten molybdenum deposit is divided into two mineralization zones:Xikengwu(Ⅱ)and Wangfang(Ⅰ).According to the mineralization characteristics of copper,tungsten and molybdenum,it can be further divided into copper(tungsten)mineralization zone and molybdenum mineralization zone.The copper(tungsten)mineralization zone is consistent with the skarn zone,while the molybdenum mineralization zone is closely related to the inner and outer contact zone of the main body,and they overlap in some parts.The ore types are skarn copper(tungsten,molybdenum)ore,fine vein disseminated porphyry molybdenite ore and fine vein hornstone molybdenite ore.There are three different types of altered rocks in the mining area:skarn,altered porphyry and altered surrounding rock.Based on the analysis,the genetic type of Nanchong copper tungsten molybdenum deposit is a composite deposit of porphyry molybdenum deposit and skarn copper tungsten deposit,which is a specific deposit combination.
