The Mineral Resources of the Bor Metallogenic Zone: A Review

<p>The Bor metallogenic zone is one of the most important metallogenic units in the Republicof Serbia. Volcanic processes in this unit are characterized by the domination of extrusivevolcanic activity, and the change of depositional environment during the numerous volcaniccycles, as well as facial transitions and huge deposition of syn- and post eruptive resedimentedvolcanoclastics. The predominant metals in the Bor metallogenic zone are copperand gold, accompanied by iron, base-metals, silver, molybdenum, and minor platinumgroupelements. The most prominent morphogenetic types of deposit comprise porphyrycopper-gold, cupriferous pyrite, massive base-metal sulphides and hydrothermal veins,iron oxides skarns, carbonate replacement polymetallic deposits, volcanogenic epithermalgold mineralization of the high sulphidation type, and exceptionally rare clasts of coppersulphide ore mechanically accumulated in small sedimentary basins filled by pyroclastics.The total production of the Bor metallogenic zone since 1902 has been near 652 Mt ofore with 4.93 Mt of copper and 280 tons of gold. Mineral resources of the Bor metallogeniczone are estimated at over 20 millions of tons of copper and 1,000 tons of gold. Themain geological characteristics of selected metallic mineral deposits in this area are describedin this paper.</p>
