探讨红井金矿地质特征及找矿标志

Discussion on the geological features of gold deposit and prospecting well

哈密市红井金矿地处新疆哈密市境内,马庄山弧后盆地以及库鲁克塔格-星星峡大陆碰撞带偏东方向(塔里木板块)的位置上是该矿大地构造分布所在,石炭系是该区的主要地层出露,且还有第四系以及长城系与二叠纪和寒武纪地层。红柳园组(下石炭统)是其主要的含矿地层,碳酸盐岩以及火山岩夹碎屑岩是其主要的建造特征。该区断裂构造发育,主要以NE向及NEE向为主,NW向次之。NEE向断裂规模较大,以沙泉子和尖山子峡断裂为主,两条断裂均起着控岩控矿的作用。NEE向断裂及其次级断裂控制着蚀变带及矿脉的分布。岩浆活动频繁,区域火山喷发活动主要发生在石炭世早期,对矿床成矿影响强烈。文中主要对红井金矿地质特征及找矿标志进行探讨,希望为该区找矿工作提供参考。

The city of the red gold deposit in Hami is located in the territory of Xinjiang Hami City,mountain arc basin and Ma Zhuang Kuruktag XINGXINGXIA continental collision zone easterly direction(Tarim plate)on the position of the mine tectonic distribution of Carboniferous strata in this area is mainly exposed,and Quaternary and the Great Wall,and Cambrian and Permian strata.Hongliuyuan formation(Lower Carboniferous)is the main ore bearing strata,carbonate rock and volcano rocks intercalated with clastic rocks is the main construction features.The fault structure in this area is developed mainly by NE direction and NEE direction,and NW is the next.NEE faults in large scale,to SHAQUANZI and Jianshanzi gorge fracture,two fracture plays a role in controlling rock and ore.The distribution of alteration zones and veins is controlled by the NEE fault and its secondary fracture.Magmatic activity is frequent,and regional volcanic eruption occurs mainly in the Early Carboniferous period,which has a strong influence on the mineralization of the deposit.This paper focuses on the geological characteristics and prospecting criteria of gold well discussed,hoping to provide reference for the prospecting work.
