Study on Pyrite Typomorphic Peculiarities of Donggouba Gold-Silver Deposit, Shaanxi

Chen Shengping Xiao Keyan Wu Youcai (China University of Geosciences, Wuhan 430074)  
The component of the pyrites has a deficit in sulphur and much J low in cobalt. The crystal form is mainly in a, ae and aeo type, and the thermoelectric peculiarities are n or pn type. The typomorphic characteristics in the four dimensions of the deposit show that it is of polygenetic type. The peculiarities of pyrites as follows are ore guide: less deficit in sulphur, a paramater with the mean value and large variance value, crystal form value varieting in 14~-152.
