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.
