The Urumieh-doktar magmatic arch is filled with the magmatic rocks associated with pyroclastic and volcaniclastic rocks along the active edge of the Iranian plate. This magmatic rock represents the former in the Urumieh area, which crossed the Upper Jurassic formations and is discordantly covered uncomfortably with fossil limestone from the Lower Cretaceous (Berberian and King, 1981). Lava flows and pyroclastic that belong to the Pliocene to the youngest quaternary rocks. These youngest rocks result from changes in geothermal gradients as a result of elevation (Berberian and King, 1981)
Sanandaj-Sirjan area (SZ)
The Sanandaj-sirjan area is part of the tectonic and metamorphic magmatic belt of Zagros. The region consists The region is composed of sedimentary and metamorphic rocks from the Palaeozoic through the Cretaceous that were formed on the former active margin of an Iranian microcontinent that drifted during the late Jurassic Period (Berberian and King, 1981; Golonka, 2004)
The Imbricate zone is located between the Zagros Thrust Front from the northeast and the High Zagros Reverse Fault from the southwest (Al-Qayim et al., 2012). Formed following the subduction of the upper Cretaceous and the collision of the continental Pliocene, it represents the innermost part of the deformed Arabian margin, with dolerite-athletic platelets on the NE Arabian margin. Imbricate structures indicate multiple phases of deformation. Folding and re-folding include mesoscopic fold, box folds, and multiple faulting (Agard et al., 2005; Alavi, 1994; Berberian, 1995).
The Zagros Simply Folded Belt forms a vast outer domain folded into the Arabian continental margin. The area is separated from the foreland basin of the Persian Gulf-Mesopotamia by flexion of the mountain front (Falcon, 1961).
