| 中文摘要: |
| 为了了解黑石山地区铜多金属矿区的矿床成因,文章研究了该区域的地球化学特征,在异常区内,发现有金、多金属矿点存在,有八路沟、车板沟南、沙丘沟口等6个多金属矿(化)点,Au、As元素在区内分布不均匀,有局部富集地段存在,有利于矿体的形成；区内断裂构造、矿点、异常三者相对较为吻合,区内该异常的形成与区内多金属矿点、矿带、断裂构造具有密切的联系；异常北区内黄铁矿沟处有北西、南北向两组断裂相交,黄铁矿沟金矿点分布于该异常范围内；矿床成因为接触交代作用形成多金属矿体、断裂构造为储矿场所、热液叠加交代形成伴生金矿体,并对矿区内伴生矿产进行了综合评价,研究为实际工程勘探提供了技术支持。 |

| In order to study the genesis of ore deposits in the copper-polymetallic mining area, in this paper, the geochemical characteristics of the region are studied, and in the geochemical characteristics, gold and polymetallic occurrences are found in the anomaly area, and there are 6 polymetallic ore points, such as Balu ditch, Cheban groove, Shaqiu groove, etc., Au, As elements are unevenly distributed in the region, there are local enrichment areas, it is advantageous to the formation of ore bodies, the fault structures, occurrences and anomalies in the area are relatively consistent, and the formation of the anomaly in the region is closely related to the polymetallic occurrences, belts and faults in the area. The north-west and north-south Neihuang Iron Ditch in the anomalous North region intersect with two groups, The gold deposits in pyrite Ditch are located in the anomaly range, because of the contact metasomatism, the ore deposit is formed, the fault structure is the ore deposit place, the associated gold body is formed by the hydrothermal superposition, and the associated minerals in the mining area are evaluated comprehensively, and the research provides technical support for the practical engineering exploration. |
