摘要
///The Shuangwang gold deposit,located in Devonian stratum of the west Qinling,Shanxi Province,is a low-grade large breccia-type gold deposit.The typomorphic characteristics of pyrite,which is the main gold-bearing mineral,are studied in detail in this paper.The main crystal forms of pyrite are the {111} and {hk0},which accounts for 75%.While the crystal form of {100} is 25%.The diagram of crystal form values exhibit the gold potentiality increasing from east to west,with the trend extending to the west of exploration line No.79.The thermoelectric coefficients of the pyrites range from -250 to 250 μV/℃.The thermoelectric conductive type of pyrites is mainly N-P type with the characteristics of N type and P type.The P type increases at the low part of the west ore body.
