Abstract :
Khosrow-Abad iron deposit is located in the northeast of Kermanshah in Sanandaj-Sirjan geotectonic zone. The units outcropped in the area are the (iron-rich) andesitic volcanics at the lower part of the sequence overlaying limestone. The aforementioned complex by the name of Songhor volcanosedimentary complex has been metamorphosed up to greenschist facies. Iron rich andesite and limestone-units have been intruded by a granitic body led to a contact metamorphism and subsequent alteration by hydrothermal fluids, extracting iron from basaltic andesite and deposited it in the limestone adjacent to basaltic andesite and at the contact of granite. Iron occurrence confined to the contact of granite in carbonates and existence of skarn mineralogy support the occurrence of an iron skarn deposit, but detailed studies on textures and structures suggest the source of the iron from the volcanosedimentary complex and its basaltic andesites.
