摘要
Daping Sn polymetallic deposit occurs in Mesoproterozoic Sibao Group,the oldest strata in northern Guangxi,most orebodies are in network(thread) veins which occurs in Sanfang granite mass and wall-rocks of exo-contact zone which are controlled by NE-NNE strike fault and NW-NNW strike fault structure.The ores are veinlet disseminated ores or in block structure,with an average grade of Sn 0.175%~3.368% and Cu 0.661%~12.070%.The primary metal mineral is cassiterite,with pyrite,chalcopyrite,sphalerite and ilmenite as accompanying minerals.The natural types of the ores are cassiterite-quartz-type and cassiterite-chlorite-quartz-type;the vein minerals are chlorite,quartz and sericite;the wall rock alterations are silicification,chloritization,sericitization and biotitization.The author believes that the genesis of the deposits in the mining area is magmatic hydrothermal filling(replacement) deposit.
