以黔西南金矿区为例,利用GIS技术分析已知矿床(点)与各地质异常间相关性,开展找矿预测研究. 通过运用GIS技术分析已知金矿床(点)与地质线型异常和地质面型异常的空间位置关系,开展地质线型异常Buffer(缓冲区)和地质面型异常叠加分析,确定其找矿有利地段,以此为基础分析组合异常找矿有利度,进而圈定研究区一类找矿远景区15个,二类找矿远景区11个,三类找矿远景区4个,实现了找矿预测的定量化分析研究.
以黔西南金礦區為例,利用GIS技術分析已知礦床(點)與各地質異常間相關性,開展找礦預測研究. 通過運用GIS技術分析已知金礦床(點)與地質線型異常和地質麵型異常的空間位置關繫,開展地質線型異常Buffer(緩遲區)和地質麵型異常疊加分析,確定其找礦有利地段,以此為基礎分析組閤異常找礦有利度,進而圈定研究區一類找礦遠景區15箇,二類找礦遠景區11箇,三類找礦遠景區4箇,實現瞭找礦預測的定量化分析研究.

This paper correlates occurrences of gold deposits and geological anomalies in southwestern Guizhou u-sing GIS technology,which has been suggested as an useful approach for mineral resource prospecting. Through GIS a-nalysis of spatial relations between linear and planar anomalies of some gold deposits and occurrences,and in combina-tion with analysis of geological linear anomaly buffer and geological planar anomaly,some areas are targeted as bearing potential for further exploration. Based on that,prospecting favorability is comprehensively analyzed,leading to the de-lineation of 15 first-class prospective areas,11 second-class prospective areas,and 4 third-class prospective areas. The work has accomplished quantitative analysis of mineral resource prospecting.
