Abstract


DISTRIBUTION OF ORE MINERALS IN THE KUPFERSCHIEFER OF THE LUBIN–SIEROSZOWICE DEPOSIT

Abstract. The paper discusses spatial distribution of ore minerals within the Lubin–Sieroszowice copper deposit in the Kupferschiefer horizon. Maps of the distribution of the chalcocite group of sulphides, bornite, chalcopyrite, covellite, tennantite, galena, sphalerite and Fe sulphides were constructed based on 2500 analyses of chip samples. In order to show a spatial distribution of major ore minerals, the Surfer 9.0 program was applied. Values of parameters in the square grid were calculated using the point kriging method. Analysis of ore minerals distribution shows that the chalcocite group of minerals predominates in the deposit. The richest chalcocite zone occurs in the central part of the deposit. In its eastern part, several ore minerals, especially bornite and chalcopyrite, prevail locally over the other sulphides. A redox barrier is a key in understanding the spatial distribution of ore minerals in the deposit.
