甘肃北山霍勒扎德盖金矿控矿因素分析及找矿预测

Analysis of ore-controlling factors and prospecting prediction of the Huolezhadegai gold deposit in Beishan, Gansu

霍勒扎德盖金矿位于甘肃北山北带,金矿体产于石英闪长岩体内的构造带中,通过研究认为成矿岩体是基性下地壳熔融形成的埃达克岩浆快速穿过地壳深部进入地壳浅部形成的,至地壳浅部成矿流体出溶演化成矿。霍勒扎德盖金矿矿石样品中发育有铜的伴生矿物,预测岩体深部可能存在斑岩型矿床。通过对发现金矿体和控矿构造进行分析,根据构造特征和岩体的分布范围,预测矿体的赋存部位,指导进一步工作。

Huolezhadegai Gold Mine is located in the northern belt of Beishan, Gansu. The gold ore body is produced in the structural belt of the quartz diorite. Through the research, it is believed that the ore-forming rock mass is formed by the Adak magma entering the shallow crust. The ordake magma formed by the formation of the ore-bearing rock mass is rapidly formed through the deep crust and into the shallow crust, and the ore-forming fluid is dissolved and evolved into ore.in the shallow crust. The associated minerals of copper are developed in the ore samples of the Huolezhadegai gold mine. It is predicted that porphyry deposits may exist in the deep part of the rock mass. Through the analysis of the discovery of gold ore bodies and ore-controlling structures, According to the structural characteristics and the distribution range of the rock mass,the occurrence of the ore body is predicted and further work is guided.
