小秦岭义寺山金矿S402矿脉找矿前景分析

An Analysis of Prospecting Prospect of S402 Vein Yisishan Gold Deposit,Xiaoqinling

义寺山金矿床位于小秦岭金矿田最东端,属典型的糜棱岩型金矿床。对矿床地质特征、主矿脉地质特征、矿床成因进行了分析、总结,并基于GIS空间分析功能对矿体趋势进行了预测,认为矿脉深部及走向上仍有一定找矿前景,指出了有利的成矿区域:第0勘探线-100~-50 m标高、第4勘探线-100~100 m标高、第8勘探线-100~200 m标高、第12勘探线-100~550 m标高。

The Yisishan gold deposit,located at the easternmost end of the Xiaoqinling gold field,is a typical mylonite-type gold deposit.Geological characteristics of the deposit,the main vein,and its genesis were analyzed and summarized.The ore-body trend was predicted using GIS spatial analysis functions.It is considered that there are still promising prospects for exploration along the vein’s depth and strike,and favorable ore-forming zones are identified as follows:the 0 exploration line at-50 to-100 m elevation,the 4th exploration line at 100 to-100 m elevation,the 8th exploration line at 200 to-100 m elevation,and the 12th exploration line at 550 to-100 m elevation.
