TRACE ELEMENT GEOCHEMISTRY OF THE GAOSONGSHAN GOLD DEPOSIT IN XUNKE COUNTY, HEILONGJIANG PROVINCE

With multivariate statistical analysis, the trace element geochemistry of the Gaosongshan gold deposit in Xunke County, Heilongjiang Province is studied. The result shows that the element of Au is closely related to Ag, As, Sb and Pb in the gold deposit. Based on the association and correlative character of elements, the trace elements can be divided into five assemblages, i.e. 1) Au, Ag, As, Sb, Pb and Mo; 2) Co, Ni, Mn, and -Sn; 3) Cu and W; 4) Hg and Bi; and 5) Zn and Sn. The variation of trace elements in vertical direction indicates that, in different elevations of gold orebody, there exits superimposition of the indicator element between head-halo and tail-halo, orebody and tail-halo, headhalo and orebody, respectively. All the characteristics suggest that the metallogenic process in the orefield very complex, with superposition of mineralization.
