个旧矿区高松矿田锡多金属矿床找矿效果的浅析

A way to improve tin polymertallic ores prospecting efficiency in Gaosong ore district of Gejiu ore field

个旧矿区高松矿田是一个以层间氧化矿床为主,深部有接触带矽卡岩型硫化物矿床产出,为锡、铅、银富集程度较高的锡多金属矿田,其中层间氧化矿床是目前云南锡业集团公司松树脚锡矿地质找矿的主要对象。以高松矿田为例,对区内矿床的产出特征、找矿方法进行了分析、评述,同时对提高找矿效果的途径提出了认识。

Gaosong ore district in Gejiu ore field is a tin, lead and silver highly accumulated tin polymetallic ore field, mostly composed of interlayer oxidation deposits with skarn type sulfide deposit on the contact zone at the deep. The interlayer oxidation deposit is the main target for geological prospecting in Songshujiao tin deposit, executed by Yunnan tin Industry group company Ltd. , Taking Gaosong ore district as example, the paper made an analysis and review on the occurrence of the deposits in the region and prospecting methods while a understanding on the way of improving ore searching efficiency was proposed.
