摘要
东坪金矿自然金形态多样，主要以包裹金和裂隙金为主。自然金的粒度较粗（平均为０．１５２ｍｍ），成色高（平均为９６５．５）。自然金的八面体和立方体聚形结构和晶石浮晶特征指示金矿床的形成环境较深。
The natural gold from Dongping gold deposit is various in morphological characteristic,mainly in form of inclusion gold and fissure gold with large grain size (0.152mm on the average)and high fineness(965.5 on the average).The features of octahedron and cube combination texture, and of floating crystals show that the gold deposit occurred in a deep environment, belonging to replacing remelting medium high temperature hydrothermal deposits.
