摘要
厘定了碱性岩型金矿床的概念 ,总结了与金矿床有关的碱性岩特征 ,从地球动力学角度 ,分析了碱性岩及其有关矿床形成的构造环境 ,讨论了碱性岩的起源演化及其与钙碱性岩共生的内因。将我国主要的碱性岩型金矿床划分为浅成热液型和中深脉状型 2个亚类 ,在对比分析了国内外碱性岩型金矿床特征基础上 。
In this paper,the author assured the concept of gold deposits associated with alkaline rocks,discussed the characteristics,origin and evolution,and the paragenetic relationship to calc alkaline rocks of the alkaline rocks related to gold mineralization,analysed the tectonic setting of alkaline rocks and their related gold deposits. According to their characteristics,alkaline rock type gold deposits are divided into two types,which are meso deepth vein gold deposits and epithermal gold deposits.Based on the systematic research on the metallogenic geological and geochermical characteristics,metallogenic structural setting, the geological descriptive model and the genetic model of alkaline rock type gold deposits are put forward.
