摘要
通过对陕西金矿资源的分析、总结,将陕西金矿成因类型划分为7类1 4亚类;与金矿有关的成矿系列划分为3个矿床成矿系列组合,7个成矿系列类型,1 0个成矿系列和4个亚系列;金矿床空间分布严格受隐伏基底和出露基底,隐伏岩体、重磁吻合构造,构造和成矿时代的控制;与金成矿有关的Ⅲ级成矿区(带)有4条,有关的Ⅳ级成矿区(带)有1 0条,有关的Ⅴ级主要金成矿区(带)有1 6条;提出了金矿新的找矿方向,为今后本区金矿地质找矿的新突破提供信息。
Analysis of the gold resources occurring in Shaanxi Province has attributed the genetic types of gold deposits into 7 types and 14 subcategories; the ore-forming sequences which are related to gold mineralization into 3 metallogenetic combinations and 7 types of mineralized sequences; 10 metallogenetic sequences and 4 sub-sequences. The distribution of gold deposits is controlled in space strictly by buried and outcropped basement, buried rock bodies, coincide structures of gravity and magnetic fields, tectonics and metallogenetic epoch. There are 4 zones of 3-class, 10 zones of 4-class and 16 zones of 5-class metallogenetic zones found to be related to gold mineralization. Some new potential places for further prospecting gold deposits in Shaanxi Province have been recommended in this article.
