Geology map of Salmas is the study area that located between 44 30' to 45 E and 38 to 38 30'N. The city Salmas is the largest population center in the area. It is accessible through Khoy-Salmas-Orumiyeh road. General morphology of the sheet can be classified into two portions, a high relief zone at west and a low plain zone at east. Tectonically, this sheet is part of the Western Alborz-Azarbaijan zone. It has two distinct lithofacieses. The south and center of the area include metamorphosed acid volcanics, marble, amphibolite and gneiss of Precambrian, where metamorphosed diorite and gabbro intrusions also exist.
The northern portion of sheet is covered by upper Cretaceous-Paleocene ultramafic, serpentinite, gabbro, gneiss, meta-diorite, basalt, marble, pelagic limestone, and chert. The Yazdkan-Chahrsotun Fault separates these two portions. Considering the lithology of the area, it is has the potential of building stones, iron, ilmenite, silica, gypsum, salt, pumice, and hot springs and geothermal energy.
