  • The Suichang mine is the largest silified vein-type silver-gold mineralization system in Southeast China, whose ore bodies are controlled by shear zones developing in Lower Proterozoic gneiss terrene with initial migmatization, which is covered by Upper Jurassic and Lower Cretaceous volcanic rock system and cut by acidic igneous veins of Jurassic and Cretaceous. The conclusions are as follows: (1) The ore-forming fluid is defined as superhigh tectonic-metamorphic fluid on the base of: ① δ (D)-δ(18O) values; ②fluid inclusions; ③trace elements of pyrite from ores. (2) The shear zone silicifed orebodies occurred in Proterozoic, Jurassic and Cretaceous, which have been transformed in part by ore-bearing comb quartz vein of volcanism.
