Abstract
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.
Highlights
The Bor metallogenic zone senso stricto belongs to the BorSrednogorie metallogenic zone which is a part of the Tethyan Eurasian Metallogenic Belt (TEMB) (JANKOVIĆ, 1976)
Porphyry copper deposits (PCD) formed in the domain of dyke systems above magmatic complexes are localized in hydrothermally altered Upper Cretaceous andesites and pyroclastites as well as in volcano-sedimentary rocks, which were penetrated by numerous quartz-diorite porphyry (Veliki Krivelj deposit) (Fig. 5)
Officially confirmed, measured and indicated copper and gold resources in During more than 100 years of exploration it was established that cooper and gold mineralization are not uniformly distributed in the Timok Magmatic Complex (TMC)
Summary
The Bor metallogenic zone senso stricto belongs to the BorSrednogorie metallogenic zone which is a part of the Tethyan Eurasian Metallogenic Belt (TEMB) (JANKOVIĆ, 1976). This the Alpine-Balkan-Carpathian-Dinaride geodynamic province (ABCD) is a part of the Alpine-Himalayan orogenic system that extends from Western Europe to South East Asia (HEINRICH & NEUBAUER, 2002; SCHMID et al, 2008). The Bor-Srednegorie metallogenic zone as a part of the Carpatho-Balkan metallogenic province extends from Lilieci - Linbcova and Bozovici in the north, over Bor to Burgas, proceeding into the Black sea and Tracia in Turkey (JANKOVIĆ, 1980, 1990, 1997). The ore deposits are grouped into several ore fields and districts, each characterized by some specific genetic features
