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.enTimok Magmatic Complexstratigraphyaga datavolcanismmineralizationconferenceObject
