西藏仲巴县强龙铜钼矿地球化学特征及找矿研究

Geochemical Characteristics and Prospecting of the Qianglong Cu-Mo Deposit in Zhongba,Tibet

HS(H)-20-甲1强龙异常是一个土壤地球化学测量异常,该异常的确定经历了从小比例尺到大比例尺逐次开展化探扫面、缩小找矿范围的过程。异常元素主要为Cu、Mo、W、Sn、Pb、Ag、Au、Zn等,与地表矿体分布对应较好。通过异常三级查证工作,证实调查区内发现的两个斑岩体中的Ⅰ号斑岩体为主要含矿斑岩体。异常元素分带特征及R型聚类分析结果表明矿床成因类型为斑岩型铜矿。

HS(H)-20-A1Qianglong anomaly is a comprehensive soil geochemical anomaly composed of Cu-Mo-W-Sn-Pb-Ag-Au-Zn anomalies.Anomalous area corresponds to the surface distribution of the Cu orebody.The Class C follow-up survey of the anomaly indicates the main ore-bearing porphyry intrusion is porphyry intrusionⅠ.R cluster analysis shows that the deposit is a porphyry Cu deposit.
