摘要
阐述了根据金成矿的特点研究金成矿地质背景、成矿作用、控矿因素,建立矿床结构模型,总结找矿标志,并利用能反映隐伏矿信息的地球化学勘查方法(如原生晕、次生晕、偏提取、地电化学等)及能反映与隐伏矿有关的场属性结构特征的地球物理勘查方法(浅层地震、激电、瞬变电磁、大地电磁测深等)来预测隐伏矿。提出成矿作用研究与方法技术有机结合形成综合方法系统是隐伏金矿预测的有效方法组合。
The paper discusses establishment of deposit structure model and exploration indicators through the research of geological backgrourd,ore-forming processes,ore-controlling factors for gold metallogeny according to the metallogenic characteristics and using geochemical exploration methods (such as primary halo, secondary halo, partial extraction and geo-electrochemistry, etc.) reflecting concealed ores' information,and geoelectrochemistry,etc. reflecting concealed ores' information,and geophysical prospecting methods (sallow seismic,IP,transient electro magnetic method and magnettelluric sounding, etc. ) reflecting field structure characteristics associated with concealed deposit to predict the concealed deposit. It is proposed that establishing a comprehensive method system by intrinsic combination of metallogenic research and technological development is effective for concealed gold deposit prediction.
