Petrogenesis and Tectono-Magmatic Setting of Meso-Cenozoic Magmatism in Azerbaijan Province, Northwestern Iran

There are widespread Cenozoic magmatic rocks in the prei-Arabian part of northern Zagros suture zone, which form the continental crust of this part of Alpine – Himalayan orogenic belt (Fig. 1). Although the age of these rocks ranges from Cretaceous to Quaternary, but the main magmatic phases belong to Cretaceous, upper EoceneOligocene, upper MiocenePliocene and plio-Quaternary. The magmatism occurred in Meso-Cenozoic periods due to convergence of the Arabian and Eurasian plates. The time and space distribution of MesoCenozoic magmatism in Azerbaijan between Arabian and Eurasian plates and their tectonic setting, are the major question in geodynamics of the eastern Mediterranean and Eastern Alpine-Himalayan belt. In this paper, new geochemical data of Cenozoic magmatic rocks of Arasbaran region (analyzed by XRF method in Miami University) are used for interpreting petrogenesis of these rocks and determining their origin, nature of magma and its evolution. The time and space distribution of Late MesozoicCenozoic magmatic rocks of the study area are also compared with the adjacent region in Azerbaijan, Armenia and Eastern Turkey. The authors try to find the relationship between magmatism and mineralization in time and space and to locate the probable occurrence of different types of mineralization associated with various magmatic events in the study area.
