甘肃省肃南县红尖一带重晶石及多金属矿矿床成因及找矿方向

Genesis and prospecting direction of barite and polymetallic ore deposits in Hongjian area,Sunan County,Gansu Province

由于甘肃省肃南县红尖一带重晶石及多金属矿勘查环境恶劣,导致欠缺对矿区成矿规律认知,为此提出甘肃省肃南县红尖一带重晶石及多金属矿矿床成因及找矿方向研究。首先从地层作用、构造作用、变质作用、火山活动以及围岩蚀变方面,对红尖重晶石及多金属矿床成矿成因进行了分析,然后分析出矿床东北部重晶石矿、西北部钨矿以及西南部黄铜矿三次重要找矿方向。

Due to the poor exploration environment of barite and polymetallic ore in Hongjian area of Sunan County,Gansu Province,which leads to the lack of recognition of the metallogenic law of the mining area,this paper puts forward the genesis and exploration direction of barite and polymetallic ore in Hongjian area of Sunan County,Gansu Province.Firstly,the metallogenic genesis of Hongjian barite and polymetallic deposits is analyzed from the aspects of strata,tectonism,metamorphism,volcanism and wall rock alteration.Then,the three important prospecting directions of barite in the northeast,tungsten in the northwest and chalcopyrite in the southwest are analyzed.
