安徽枞阳牛头山铜矿床地质特征及找矿前景
|
摘要
通过对安徽枞阳牛头山铜矿床的区域地质背景、矿体赋存规律、矿化蚀变特征、矿石类型及结构构造等的综合分析研究,总结归纳出矿体赋存于上侏罗统龙门院组矿化蚀变带("褪色"蚀变带)及部分断裂破碎带中,矿床属次火山岩期后中低温热液型。在此基础上分析了找矿前景,认为控制龙门院组矿化蚀变带中沿矿体倾向和走向的深部矿体,以及次火山岩体外侧构造破碎带控矿的脉状铜矿体,可作为今后进一步找矿的工作重点。
Based on the comprehensive analysis and study of the regional geological setting, ore body occurrence regularity, mineralization and alteration features, ore types, textures and structures of the Niutoushan copper deposit in Zongyang County, it is concluded that the ore bodies were hosted in the Upper Jurassic Longmenyuan Formation mineralization and alteration belt(″fading″ alteration alteration zone) and part of the fractured fault zone, and this deposit is a sub-volcanic rock mid-low temperature hydrothermal deposit. On this basis, the ore prospecting prospect was analyzed. It is pointed out that the next step should continue to recourse and control the deep ore body along the ore body direction and strike direction in the mineralization and alteration belt of the Longmenyuan Formation and the external structural fragmentation control of the subvolcanic rock body. The veined copper ore body of the mine can be used as a focus of the further work.
