青海一棵松铅锌银矿地质特征及找矿标志

Geological characteristics and prospecting criteria of Yikesong lead-zinc-silver deposit,Qinghai

一棵松铅锌银矿区存在对成矿十分有利的地层、构造和岩浆岩,具有良好的物化探异常,对少数已知矿体浅部进行控制,发现矿体具一定规模,且矿种多样。目前矿区发现3条矿化带,圈定了50条矿体。在总结成矿特征的同时,详细论述了矿床控制因素及找矿标志;从区域成矿地质条件、矿床成矿地质环境分析,该区具有优越的成矿条件,明确了该区的找矿思路。

It was discussed that the geological characteristics and metallogenic geologic back-ground of Yikesong lead-zinc silver ore deposit,summarized the prospecting marks in this paper. The existence of the metallogenic tectonic and magmatic rocks is good for ore - forming, with good geophysical anomalies. It was known orebody in a shallow control,found with a certain scale,ore minerals and varied. At present three mineralization belts were found in the mining area ,50 ore bodies were selected. In the summarization of metal-logenic features at the same time, the author discussed the control factors and ore prospecting marks from regional ore-forming geological conditions deposti metallogenic geological environment analysis, and discovered that there are superior metallogenic conditions, which will promote the prospecting idea of the region.
