新疆某地11号岩体金矿矿床特征

Characteristics of the Gold Deposit in No.11 Rock Body in a Location of Xinjiang

矿区出露下石炭统希贝库拉斯组、包古图组、太勒古拉组,为1套火山碎屑岩及碎屑岩,矿区圈定12条金矿体,矿石自然类型确定主体为含金石英脉型,少量含金破碎蚀变岩型。矿床控矿因素为火山岩控矿、构造控矿、岩浆作用控矿。针对11岩体金矿开展验证,了解金矿体赋存空间、形态、品位、厚度、含矿岩性、成矿规律及金资源量前景,认为其矿床成因为与火山热液有关的含金火山岩型矿床,具有较大找矿潜力。

Lower Carboniferous Xibekula Formation,Baogutu Formation and Talegula Formation are exposed in the mining area,which is a set of volcaniclastic rocks and clastic rocks.12 gold ore bodies are delineated in the mining area.The natural types of ores are determined to be mainly gold-bearing quartz vein type with a small amount of gold-bearing fractured altered rock type.The controlling factors for the ore deposit include volcanic rock control,structural control,and magmatic activity control.Verification work was conducted on the No.11 rock body gold deposit to understand the spatial distribution,morphology,grade,thickness,ore-bearing lithology,metallogeny,and the prospective outlook for gold resources.It is concluded that the genesis of the deposit is attributed to a gold-bearing volcanic rock-type deposit related to volcanogenic hydrothermal activities,harboring significant potential for further exploration.
