摘要
南明水金矿床是卡拉麦里地区典型的造山型金矿床之一,亟需解决制约找矿突破的关键问题,拓展深部和外围找矿空间。通过野外调查、岩矿鉴定和综合分析,运用勘查区找矿预测理论,查明成矿地质体为卡拉麦里韧性剪切带,成矿构造与成矿结构面为NW-NWW向和NE-NEE向韧-脆性高角度逆冲断层,成矿作用中矿化蚀变为直接找矿标志。初步建立南明水金矿床“三位一体”找矿预测地质模型,为后期矿区找矿勘查工作部署提供重要依据。
The Nanmingshui gold deposit is one of the typical orogenic gold deposits in Kalamaili area,which needs to solve the key problems restricting the prospecting breakthrough and expand the deep and peripheral prospecting space.Based on field investigation,rock ore identification and comprehensive analysis,using the theory of prospecting prediction in exploration area,it is found that the ore-forming geological body is the Kalamaili ductile shear zone,the metallogenic structures and structural surface are the NW-NWW and NE-NEE trending ductile-brittle high-angle thrust faults,and the characteristics of mineralization can be used as the direct ore-prospecting indicators.In this paper,the“trinity”prospecting geological prediction model of the Nanmingshui gold deposit is preliminarily established,which provides an important basis for the arrangement of prospecting and exploration in the later period.
