THE MAIN GEOCHEMICAL ASSOCIATION OF THE SULFIDES OF LEAD-ZINC MINERALIZATION IN TREPÇA MINERAL BELT- HAJVALIA MINE, KOSOVO

This paper presented the distribution of major metals (Pb, Zn, Ag and Au) and accompanying metals in Hajvalia mineral deposit. With special emphasis, we studied the main geochemical association of lead (Pb) and zinc (Zn) sulfides mineralization. The geochemical data suggest a very strong correlation of Ag with Pb, which could be related to the associated of pyrargyrite with galena as well as with isomorphic enrichment of galena with Ag. From the available composite data (30 samples), average silver (Ag) for each 1% lead (Pb) is 14.75 g/t. According to the factorial analysis, the result of these geochemical associations is as follows: Pb-Zn-Ag-(Cd-Cu); Sb-(Cd); Bi- (Cu).
