| 摘 要： | 利用微分干涉显微镜等手段对小秦岭金矿含金石英脉中不同成矿阶段的石英晶体微形貌进行了研究。石英晶体{101^-1}、{011^-1}、{101^-0}单形晶面上不同特征的微形貌对了解石英晶体的生长机理、生长速率、生长环境的变化及成矿溶液的过饱和度具有重要意义，同时也可提供成矿阶段划分及晶体生长时热力学条件的信息。

| Abstract: | The micromorphology of quartz crystals formed at different ore_forming stages in auriferous quartz veins are studied by means of differential interference microscope. The micromorphologic characteristics of quartz crystal faces of {1011},{0111} and {1010}help to understand the mechanism and the rate of crystal growth, the oversaturation of ore_forming solution, and the variation of the growth environment, and can also provide information for the division of ore_forming stages and the thermodynamic condition for crystal growth. |
