Geological Features of the Woxi Au-Sb-W Ore Deposit

Li Jianyan  
The Woxi Au-Sb-W ore deposit is present in slate, purplish red in colour, located at the mediumand upper members of the Madiyi Formation of the Proterozoic Banxi Group. Four kinds of structuresare recognized: reverse fault, interformational falt, post mineral fault and fold. In the mining area orebodies occur as interbeded quartz vein, network quartz vein or joint quartz vein. Gold is mainly foundin pyrite and antimonite. Mineralizations bear a relationship with decolourization, the medium to finegrained pyritization and silicilication. It is believed that the ore deposit is polygenetic, being of sedimento metamorphic and hydrothermal-reformation origins. Grounds for explaining the origions of the deposit and exploration guide are also put forward in this paper.
