内蒙古苏尼特右旗别鲁乌铜矿外围矿区岩金矿物化探特征分析

Analysis of geophysical and geochemical characteristics of rock gold deposits in the peripheral mining area of Bieluwu copper mine,Sunite Right Banner,Inner Mongolia

内蒙古自治区苏尼特右旗别鲁乌铜矿外围矿区岩金矿位于白乃庙—哈达庙铜、金、萤石四级成矿带(Ⅳ)北部,具有良好的金多金属矿成矿地质条件。本文应用1∶1万土壤地球化学测量及激电中梯测量圈定物化探异常,并结合地质条件对物化探异常进行了分析评价,确定了成矿最有利地段,通过激电剖面测量和激电测深,确定了矿(化)体在深部的空间分布特征。经工程验证该异常确定为矿致异常,说明地、物、化综合找矿方法在该区行之有效。

The rock gold deposit in the peripheral mining area of Bieluwu copper mine in Sunite Right Banner,Inner Mongolia Autonomous Region is located in the north of Bainaimiao-Hadamiao copper-gold-fluorbaryt metallogenic belt,with good metallogenic geological conditions for gold polymetallic deposits.In this paper,the geophysical and geochemical anomalies were delineated by 1∶10000 soil geochemical survey and IP intermediate gradient,and analyzed and evaluated in combination with the geological conditions.The most favorable area for mineralization was determined.With IP profile survey and IP sounding,the spatial distribution characteristics of(chemical) ore body in the deep part were determined.It was verified as ore-induced anomaly by engineering verification,which showed that the comprehensive geological,physical and chemical prospecting method were effective in this area.
