'焦家式'蚀变岩型深部金矿地质-地球物理模型——新技术新方法在金矿深部找矿中的应用

摘要

焦家断裂带、三山岛断裂带是胶西北区著名的金矿成矿带,控矿成因类型属典型的"焦家式"蚀变岩型金矿.近年来,该两大成矿带在勘查研究及深部找矿探索方面取得了一系列重大突破,其埋藏深、规模大,充分显示出其深部找矿的巨大潜力,浅部的常规物探方法模型已经建立,但常规物探在深部找矿中的难度越来越大,至今仍没有总结出一套适合深部蚀变岩型金矿地质-地球物理模型的有效物探方法,鉴于此,该文通过在深部找矿中应用较好的新技术新方法的一致性探讨,并结合成矿地质特征及钻孔资料,分析建立"焦家式"蚀变岩型深部金矿地质-地球物理模型.%Jiaojia fault belt and Sanshandao fault belt are famous gold mineralization belts in northwest region.Its ore-controlling type belongs to typical "Jiaojia type altered gold deposit.In recent years,a series of major breakthroughs have made in the exploration in these two major metallogenic belts.Its hidden depth and large scale have fully showed the great potential.Conventional geophysical method of shallow ore prospecting model has been established.But conventional geophysical prospecting in deep ore prospecting has become more and more difficult.An effective geophysical method which is suitable for geological geophysical model in deep alterated type gold deposit still can not be summarized.In view of this,through study on the application of new technologies and new methods for deep ore prospecting,combining with qualitative characteristics and drilling data,the analysis,geological-geophysical model of "Jiaojia type" deep altered type gold deposit has been establishment.
