陕西省宁强县庙坝乡朱家坝金矿地球化学特征和找矿前景分析

Geochemical characteristics and prospecting prospect of Zhujiaba Gold deposit in Miaoba Township,Ningqiang County,Shaanxi Province

朱家坝金矿位于“勉略阳三角地区”西南部,属勉县茶店子一宁强青木川金银铅锌铜硫远景区。文章在讨论成矿地质背景基础上,论述了工作区地质特征,对矿体地质特征和工作区地球化学特征进行了分析和研究。金矿赋矿岩性为石英脉,韧性剪切带及次级断裂严格控制金矿体的展布形态。圈定的化探综合异常规模较大,异常强度较高,异常元素套合较好。工作区整体成矿条件有利,具有较好的找矿前景。

The Zhujiaba Gold Mine is located in the southwest of the"Mianlueyang Triangle Area",which belongs to the“Mianxian County Chadianzi-Ningqiang Qingmuchuan Gold,Silver,Lead,Zinc,Copper and Sulfur Prospective Area”.On the basis of discussing the geological background of ore formation,the paper discusses the geological characteristics of the working area,and analyzes and studies the geological characteristics of the ore body and the geochemical characteristics of the working area.The ore-hosting lithology of gold deposits is quartz veins,and the distribution of gold ore bodies is strictly controlled by ductile shear zones and secondary faults.The delineated geochemical comprehensive anomaly has a large scale,high anomalous intensity,and good fit of anomalous elements.The overall ore-forming conditions in the working area are favorable and have good prospecting prospects.
