招平断裂带中段断裂成矿有利度分析

Analysis of fault/fracture metallogenicl favourability degree of the middle part of Zhaoping fault belt

招平断裂带是我国著名的金矿成矿带。断裂的空间展布形态特征对寻找断裂构造控矿型金矿床具有重要作用。通过断裂的遥感解译,研究了招平断裂带主断裂的走向、主断裂地表破碎带宽度以及主断裂起伏程度等成矿有利度指标,构建了基于断裂距离场的成矿有利度分析模型,并圈定研究区域成矿远景区11处,为区域地质、物化探等勘查工作提供了指导性意见。

Zhaoping fault belt is a well known Au ore belt in China.Spatial morphology of a fault extension is important to prospect the fault-control Au deposit.The favorable metallogenic degree of Zhaoping fault belt,such as strike,width of the fractural zone at surface and undulating degree of the main fault zone is interpreted on remote sensing image to build the metallogenic favorable degree model.Based on distance field of the fault 11prospects are lineated in the study area with the model thus provide guidance to further regional geological,geophysical and geochemical survey.
