摘要
金山金矿是华南规模最大的岩金矿床。本文介绍金山金矿床地质特征，认为它是一个典型的韧性剪切带型金矿，控矿构造为东西走向的推覆型韧性剪切带；提出赣东北韧性剪切蛇绿岩构造混杂带控制区域金钢成矿带时空展布的新认识；论述成矿物质来源于就地改造的双桥山群，韧性剪切带动力变质作用是最主要的成矿作用，矿床成因属于韧性剪切带变质热液型金矿床，又称“金山式”金矿。
Jinshan gold deposit is the largest scale deposit in South China. Based on the geological characteristics of Jinshan deposit, the author holds that it is a typical ductile shear zone-type gold deposit. Its ore-controlling structure is WE-striking nappe ductile shear zone. At the same time, the author proposes a new idea that the time-spacedistribution of regional An-Cu metallogenic zone was controlled by the tectonic melange zone of Northeast Jiangxi ductile shear ophiolite; and describes the ore-forming materials originated from the Shuangqiaoshan group on the Spot deformation,thedynamo-metamorphism of ductile shear zone is the most important ore-forming process,and the deposit genesis belongs to metamorphic hydrothermal type gold deposit of ductile shear zone,and it can be known as 'Jinshan gold deposit'.
