摘　　要：构造叠加晕找盲矿法在可以建模的已知矿床深部预测盲矿已取得了显著效果。本文介绍了在尚未发现矿体、未建模的勘查(新)区采用构造叠加晕法预测盲矿的理论与方法,并根据作者总结建立的热液型金及有色金属矿床深部盲矿预测的构造叠加晕“实用理想模型”,建立了在勘查(新)区预测构造-蚀变带深部含矿性的构造叠加晕“参照实用理想模型”。据此模型可快速、有效地对勘查(新)区各构造-蚀变带进行评价、深部预测,筛选出最有利成矿的构造蚀变带,提出有利成矿部位或预测靶位,从而缩小找矿范围,为进一步勘查提供依据。The method of blind ore prospecting in terms of structural superimposed halos has been successfully applied to the prediction of deep ore bodies in known deposits that can be modeled.This work studies how to extend this method to the exploration(new)areas without discovered ore bodies and modeling.According to the“practical ideal model”established by authors,which focuses on hydrothermal gold and non-ferrous metal deposits,a“reference practical ideal model”is further constructed to realize the objective aforementioned.It permits to quickly and effectively evaluate and predict the deep situation of each structure-alteration zone in the exploration(new)area.Then the most favorable structural alteration zones of mineralization are picked out,possible ore-forming positions or prediction targets are determined,and the scope of prospecting is limited,providing evidence for further exploration.
