Stratigraphy and age of rock units and mineralization in the Timok Magmatic Complex and the Bor Metallogenic Zone – a review
(University of Belgrade, Technical Faculty in Bor, 2021) Banješević, Miodrag
This study reports of stratigraphy and geochronology of rock units and mineralization of the Timok Magmatic Complex (TMC) and the Bor Metallogenetic Zone (BMZ)which belongs to theLate Cretaceous Apuseni-Banat-Timok-Srednogorje Belt (ABTS, part of the Tethyan-Eurasian Metallogenic Belt). Existing data are supplemented and systematized by the latest geological, stratigraphic and mineral exploration. The TMC developed on a continental crust composed of different types of the Proterozoic to the Lower Cretaceous rocks. The TMC consists of the volcanic/magmatic, volcanogeno-sedimentary and sedimentary units.The sedimentary processes and magmatism lasted nearly continuously throughout nearly the whole Late Cretaceous. The sedimentation lasted from the Albian-Cenomanian to the Maastrichtian. Magmatism occurred in two phases from the Upper Turonian to the Upper Campanian: V1 (90-83 Ma), V2 (83-78 Ma), with a steady decrease in age from east to west. Cu-Au porphyry mineralization take place between 87-80 Ma. Major mineralizationis related to the V1 magmatic phasepredominantly developed in the easternmost part of the BMZ.
