哈达门沟金矿13号脉的可视化成矿地质条件分析及深部预测

内蒙古哈达门沟金矿是内蒙古境内最大的黄金矿山之一。基于三维模型理论和方法,使用Surpac软件对其中的13号矿脉进行三维模型的建立,分析其矿体的主要成矿因素,包括地表、矿体、构造、岩体、蚀变等三维模型,了解矿体、岩体形态,构造特征,分析矿体与周边岩体、蚀变带及构造之间的相互关系,发现哈达门沟金矿主要受到构造控制,花岗伟晶岩脉充填早期破碎带带动了金元素的向上迁移,蚀变形成的硅质含金硫化物最终得到沉淀,形成矿体。通过建立哈达门沟13号脉金品位块体模型了解其金元素的分布情况,推测标高500m以下可能存在矿化潜力区。

Analyse metallogenic geologic conditions of Hadamengou gold deposit by establishing the three-dimensional model of 13 vein and predict deep situation of 13 vein

Hadamengou gold deposit is one of the largest gold mines in Inner Mongolia.Based on the Three-dimensional model theory and method establishing the three-dimensional model of 13 vein by using Surpac software,including surface model, ore body model ,structure model ,rock model and alteration model. Understanding the ore body and rock form and structure features, analysis the relationship between ore and rock, alteration belt, structure,found the Hadamengou gold deposit main controlled by structure,giant crystal granite dike filling early fracture zone, and so did the upward migration of gold element,alteration of siliceous gold-bearing sulfide eventually get precipitation, formed ore bodies.we also established the block model of gold grade in 13 vein and knew the distribution of gold element,speculated that elevation below 500 m there may be potential mineralization zone.
