| 摘 要： | 金家坞金矿是近年江西省地矿局物化探大队发现的新矿产地,已基本查明是一个受近东西向构造挤压蚀变带控制的变质热液型大型金矿床.金矿化产于挤压蚀变变形带中,矿体形态简单、规模大,其成矿作用大致经历了火山沉积成岩-区域变质变形-动力变质热液改造等3个阶段.文章在系统阐述该矿地质特征和成矿地质条件的基础上,对其找矿远景进行了初步分析.

| Abstract: | Jinjiawu gold deposit was found out several years ago by Geophysical and Geochemical Exploration Team, Jiangxi Bureau of Geology and Mineral Resources Exploration and Development. It is a large scale metamorphic hydrothermal deposit controlled by a nearly east - west trending structural compression alteration belt. Gold mineralization with simple shapes and large scale is located in the structural compression alteration belt, Mineralization roughly underwent volcanic .sediment - regional metamorphism and deformation - dynamical metamorphism and hydrothermal reformation, Based on expatiation of geological characteristics and mineralizing conditions, future ore, prospecting is proposed. |

| Keywords: | volcanic sediment regional metamorphism structural compression alteration belt dynamical metamorphism- hydrothermal reformation mineralization Jinjiawu gold deposit |
