新疆托里县灰绿山金矿矿床特征

Characteristics of the Huilushan Gold Deposit in Tuoli County,Xinjiang

矿区处于准噶尔弧盆带的达拉布特晚古生代弧后盆地中。矿区出露地层为下石炭统太勒古拉组下亚组,岩性为一套火山-火山碎屑岩建造,矿区出露晚石炭世浅成-超浅成相辉绿岩岩体,和成矿有密切关系。矿区分布着5个金矿体,矿石结构主要有碎裂结构、脉状结构等,矿石构造主要有角砾状构造、浸染状构造等。矿石自然类型以含金黄铁矿-磁铁矿石英脉型为主。矿床成因为高-中温热液充填交代含金石英脉型矿床。

The mining area is located in the Dalabute Late Paleozoic backarc basin of the Junggar Basin.The exposed strata in the mining area are the Lower Subgroup of the Lower Carboniferous Tailegula Formation,which consists of a set of volcanic clastic rock formations.The exposed Late Carboniferous shallow to ultra shallow facies diabase rock masses are closely related to mineralization.There are 5 gold ore bodies distributed in the mining area,and the ore structure mainly includes fragmented structure,vein structure,etc.The ore structure mainly includes angular gravel structure,disseminated structure,etc.The natural type of ore is mainly gold bearing pyrite magnetite quartz vein type.The formation of the deposit is due to the high-to medium temperature hydrothermal filling metasomatic gold bearing quartz vein type deposit.
