| 摘 要： | 蓬莱金矿位于胶东半岛北部,是一个中型热液型脉状金矿。利用分析型高分辨电子显微镜(JEM-2000FX)并配以能谱仪(EDS)对主要的载金矿物黄铁矿进行微区分析,发现成矿阶段黄铁矿晶体内部Fe、S等成分呈环带状分布。本文从耗散结构理论出发,初步探讨黄铁矿内部成分环带的成因,并论述了它的成矿意义。

| Abstract: | The Penglai gold deposit, located in the northern part of Jiaodong Penisula, is a middle, hydrothermal lode type deposit. It is along the outside contact zone of the Guojialing granodiorite. The Au carrying minerals are pyrite, quartz, chalcopyrite, galena, pyrrhotite and sphalerite, in which pyrite and quartz are the main Au carrying minerals. Microinformation of pyrites at different stages studied by electronic microscope(JEF 2000FX) equipped with spectrum(EDS) shows that there exit component zones in pyrites at syn gold mineralization stage stage. Based on dissipative structure, we discuss the dynamic genesis of component zones in pyrites at syn gold mineralization stage, and give a suggestion about the geological setting and the process of gold mineralization in Penglai gold deposit, Shandong. |
