摘要
阿尔泰-准噶尔北缘铬铁矿-Cu-Ni-Au-Pb-Zn-Ni成矿带是全国重点部署找矿勘查工作的16个重点成矿区带之一,是全球阿尔泰巨型成矿带位于中国境内的一部分。文章根据全国矿产资源潜力评价成果,结合新的成矿理论和找矿进展,对该成矿带的边界进行了新的修定;从大地构造演化历史出发,分析总结了该带区域成矿地质背景和有利成矿地质条件,进一步修订了成矿带的成矿谱系;总结了成矿带内次级成矿单元的成矿特征;对带内矿床的主要成因类型和相应的典型矿床的成矿特征进行了总结;分析了成矿带的资源潜力,并在此基础上,确定了Cr、Mo、Cu、Au、Ni、Pb、Zn、Ag为本带下一步勘查部署的主攻矿种,划分了9个远景区,其中3个为重点远景区,6个为一般远景区。此项工作对本成矿区带内下一步矿产勘查工作部署有着重要指导意义和参考价值。
The Altay-North Junggar Cr-Cu-Au-Pb-Zn-Ni metallogenic belt is one of the sixteen major metallogenic belts,which are designated as the national key exploration work.The belt is part of the Altai giant metallogenic belt within China.Based on assessment of national mineral resources and potential,new prospecting theory and advances,authors revised the boundaries of this metallogenic belt.Based on the history of tectonic evolution,this study summarized the regional geological background and its geological conditions,and further revised its metallogenic lineage.Geological features of each metallogenic unit and their corresponding deposit types and typical deposits were also summarized,with an emphasis on assessment of mineral resources.On the basis of previous research data and our results,nine target prospecting areas were defined,among them three are key areas and six are average ones.This work will have important guiding and referential significance to further geological prospecting deployment.
