THE Rushan gold deposit, being of quartz-vein type, is located in biotite monzonitic granite of Kunyushan complex pluton in eastern Shandong, China, and the orebody No. 2 is the largest mono-vein deposits found in China. The gold mineralization can be divided into three stages according to crisscross relations of the various microlodes in the deposit: Ⅰ. pre-ore stage of comb-structured milky-white quartz veins; Ⅱ. main mineralization stage of multi-metal sulphides and siderite-quartz veins; Ⅲ. post-ore stage of mottled cryptocrystalline quartz veins.
