摘要
根据主要成矿地质作用和地质背景,本文将产在中国境内的金矿床划分为9个成因类型及22个亚类。 中国金矿床的基本特征除具有世界上同类型金矿床的共同特征外,与中国大地构造发展特征有关,其成矿作用的长期性和多元性,矿源的多源性和继承性,容矿围岩时代与其成矿期的时差等特别明显。 论文总结了中国主要类型金矿床的主要特征,并附有中国金矿矿化集中区的分布略图。
Based on the predominant metallogenic geologic process and major geologic setting, 9 genetic types and 22 sub-types of gold deposits are classified in China territory.
The'inherit'property of gold,long-term & multi-period in gold mineralization,poly-metallogenic origin & sources,and varied chronological gsp between gold hosted rock & main mineralization, age-are the basic geologic features of gold deposits in China.
The causes and description of those basic features are discussed in this paper.
A sketch map of the distribution of gold mineralization concentration zones in China is presented by the author.
