ORE GEOLOGY REVIEWS, cilt.127, 2020 (SCI-Expanded)
The Guijeh Qaleh iron deposit, located in the Takab district of northwestern Iran contains ca. 0.3 million metric tons (Mt) of ore at 48 wt. % Fe. The host rocks are Eocene to Oligocene volcano-sedimentary sequences consisting of andesite, trachy-andesite to basaltic andesite flows intruded by granites to granodiorite intrusions. The hydrothermal alterations include argillic, sericitic, silicified, carbonate, and hematitic zones. Silicified and hematitic alteration zones are spatially associated with the mineralization and occur proximal to ore bodies, whereas sericite, carbonate, and argillic alteration zones are distal to main ore bodies
