青海省都兰县一棵松铅-锌-银矿多元成矿信息与找矿方向

Multiple ore-forming information of Yikesong lead-zinc-silver deposit in Dulan county of Qinghai and prospecting direction

阐述了一棵松铅-锌-银矿床的矿区地质特征,分析了在该矿区利用多元成矿信息找矿的有效性。着重对矿区构造的控矿作用、矿区地球化学特征和地球物理特征与矿化的关系进行较深入的分析。研究认为,在近EW向断裂构造两测与不同方向断裂带叠加的部位,且物探、化探异常互为套合的地段,是寻找和验证新的铅-锌-银矿体的有利部位。

Ore field geological characteristics of the Yikesong lead-zinc-silver deposit was expatiated and the efficiency of using multiple ore forming information in ore exploration in the ore field was analyzed with a focus on ore controlling process of the structure in the ore field and the relation between ore field geochemical or geophysical characteristics and mineralization. It is believed that the location on both sides of EW striking fracture and the superimposing part of the fracture zones of different directions where geophysical and geochemical anomalies are coincided are the favourable location for searching and testifying new lead, zinc and silver orebodies.
