乌宗布拉克金矿床地质特征及成矿条件分析

Geological Feature and Ore Formation Condition Analysis of Wuzongbulake Gold Deposit of Xinjiang Turpan

介绍了乌宗布拉克金矿床的地质概况:大地构造位置、矿区地质特征、矿体特征、围岩、矿石质量等,并为以后的找矿工作提出了合理的建议。通过野外考察及室内分析,得出了如下主要结论:大地构造位置上处于成矿有利地段,该金矿属于断裂破碎带有关的含金石英脉型及蚀变岩型金矿,金矿脉主要产于石英脉中,并受北西向次级断裂破碎带控制。矿体为脉状、透镜状,具一定的规模,连续性好,属稳定矿体,矿石品位变化不大。通过采样可知,4个金矿体中,L4号金矿体资源量可大幅度增加,具有很好的资源前景,其余3个矿体为非矿体。

The paper presents the geological profile of Wuzongbulake gold deposit,such as geotectonic position,mining geology and ores＇ characteristics,wall rocks,ore quality etc,and prospects some reasonable suggestion for future.In combination of field investigation and laboratory analysis,the following major conclusions were made： Its geotectonic position is favorable for mineralization;The gold deposit belongs to the gold-bearing quartz veins and altered rock type related to the fracture zone;The main gold veins mostly come from the quartz veins,and are controlled by the North-west secondary faults belt.The ore bodies are the vein and lenticular type of ore with a certain scale and good continuity.It is a kind of stable ore,and ore grade changes little.From samples,it is known that the resources reserve of No.L4 ore body can be greatly increased with a good resource prospect among four gold bodies.The other three has not belonged to the ore.
