From Paleogene to Recent time, Macedonia was part of the South Balkan extensional region, northern Aegean regime. Extension began in middle late Eocene eastern with formation a NNW-trending east-tilted half graben lying east forearc basin central Macedonia. Following short-lived period localized shortening Oligocene early Miocene second Neogene extension that continued present. Five cycles are recognized, and associated sedimentation occurred basins complex origins: (1) true graben, (2)...
The South Balkan extensional system consists of normal faults and associated sedimentary basins within southern Bulgaria, Macedonia, eastern Albania, northern Greece, northwestern Turkey. Extensional tectonism began during the final convergence across Vardar, Intra-Pontide, Izmir-Ankara suture zones, where oceanic regions closed between continental Europe fragments that make up Pelagonian, Sakar, western Anatolian tectonic units. Earliest extension latest Cretaceous– middle Eocene age...
Although North Macedonia covers only 0.7 % of the Earth's surface, it contains 3 world's mineral deposits (Jovanovski et al. 2018). Both historical and recent mining operations in country have left extensive waste deposits, particularly from focused on exploration antimony (Sb), arsenic (As), chromium (Cr), copper (Cu), lead (Pb), zinc (Zn) thallium (Tl). Over past six years, we intensively studied mineralogy geochemistry two abandoned Lojane, a former Sb-As-Cr mine, Allchar, Tl-As-Sb-Au...
In the Lojane area (North Macedonia) ores of Sb (stibnite), As (realgar), and Cr (chromite) were mined processed in a metallurgical plant until 1979.Over one million tons flotation tailings containing As, Sb, other hazardous substances are located an open dump site for waste created by mine.The is completely unprotected, its orange color reflects very high concentration arsenic (fine-grained realgar superficially altered to pararealgar).In order better understand weathering behavior these...
Secondary minerals could be effective scavengers of toxic arsenic (As) and thallium (Tl). In environments polluted by mining, these elements are abundant both in acid rock/mine drainage scenarios, as well carbonate-buffered environments. this study we have investigated the behavior As Tl during weathering mine waste dumps an associated technosol sample from Crven Dol locality (Allchar Tl–As–Sb–Au deposit, North Macedonia) contaminated with up to 142 g kg−1 18 Tl, making it As- Tl-extreme...
The laterite Ni-smelting operations at Vozarci, Republic North Macedonia have produced large amounts of smelting wastes dumped in the close vicinity smelter. We examined phase composition and chemistry various types slags (electric furnace slags, converter slag, magnetic slag) with special focus on phases containing potentially toxic elements terms their mineralogy, chemical composition, responses to weathering. Electric contain between 35 47 wt.% SiO2, 21–40 Fe2O3, 13–23 MgO; are Fe-rich...
The activities of the Sasa mine have led to industrial discharge being released into Lake Kalimanci since beginning mining activity in 1954. For this reason, an ecological risk assessment is urgently required. In present study, surficial lake sediments were analyzed using inductively coupled plasma mass spectrometry (ICP-MS), with all geochemistry data processed Statistica 8. order assess environmental pollution status, 2 factors established, while for determination chemical fractionation...
The Sasa Pb-Zn-Ag deposit belongs to the group of distal base metal skarn deposits. is located within Serbo-Macedonian massif, a metamorphosed crystalline terrain Precambrian Paleozoic age. mineralization, hosted by marbles, shows strong lithological control. It spatially and temporally associated with calc-alkaline shoshonitic post-collisional magmatism that affected Balkan Peninsula during Oligocene–Miocene time period resulted in formation numerous magmatic–hydrothermal ore mineralization...
The paper presents data about the geology, geochemistry, structure, genesis and specific features of Bučim porphyry Cu deposit which is actively mined in Macedonia.The mineralization (0.3 % Cu, 0.3-0.5 ppm Au) spatially temporarily associated with Tertiary subvolcanic intrusions latitic latitic-andesitic composition.The occurred during Oligo-Miocene time (24 to 27 Ma), a period intensive tectono-magmatic ore-forming processes..The latest results this study identify an array major ore...
