羊拉铜矿江边矿段地球物理特征及找矿方向

The Geophysical Characteristics and Prospecting Direction of the Yangla Copper Deposit Riverside Ore Section

分析矿山岩(矿)体物性特征,在江边矿段开展EH4、激电测深、高精度磁测及井中激电工作,分析不同物探方法的异常特征,不同物探方法成果互相验证,互相补充。研究综合物探异常,推测花岗岩岩体在深部形成近南北向的岩脊,布置验证钻孔ZKJ2-1,ZKJ2-1在推测矽卡岩型硫化矿位置揭露了1层矽卡岩型铜矿体和1层低品位铜矿体,结合ZKJ2-1和井中激电成果进一步分析,提出下步找矿方向为ZKJ2-1东面的岩体凹陷带可勘查矽卡岩型铜矿体,ZKJ2-1西面可勘查铅锌矿。综合物探在江边矿段取得良好的勘探效果,方法组合可在类似矿床推广应用。

The physical properties of mine rock (ore) body was analyzed,EH4,IP sounding,high-precision magnetic survey and borehole IP in the riverside ore section was carried out,the anomalous characteristics of different geophysical methods was analyzed,the results of different geophysical methods are verified and complemented each other.Studying the comprehensive geophysical anomalies,inferred that the granite rock mass forms a nearly north-south ridge in the deep,arranged drilling ZKJ2-1 to verification the geophysical anomalies.ZKJ2-1 reveals one layer of skarn copper orebody and one layer of low-grade copper orebody at the presumed location of skarn belt.The ZKJ2-1 and borehole IP results was analyzed,it is proposed that the next prospecting direction is the rock mass depression zone east of ZKJ2-1,which could explore skarn copper orebody,and the west of ZKJ2-1,which could prospect lead-zinc deposit.Comprehensive geophysical prospecting has achieved good prospecting results in riverside ore section,and the method combination can be popularized and applied in similar deposits.
