Dehzaman iron deposit is located in Khorasan Razavi province and northeastern Kashmar ـ Kerman tectonic zone. Geology of the area includes late ـ Neoproterozoic metamorphosed volcano ـ sedimentary rocks and lower Cambrian granitic intrusion. Hosted metarhyolite ـ metarhyodacite rock is formed in the subduction zone. Mineralization occurs as vein ـ veinlet, massive, disseminated, and breccia. Primary minerals are magnetite, specularite, apatite, and minor chalcopyrite and secondary minerals are malachite and hematite. Gangue minerals are chlorite, calcite, quartz, biotite ± tourmaline. Magnetites have a high concentration of REE and show a strong to the moderate enrichment of LREE related to HREE. The apatite ـ bearing magnetite ـ specularite mineralization is similar in the aspects of mineralogy, texture, alteration, host rock lithology, and magnetite chemistry to the Kiruna ـ type deposits and has the hydrothermal origin. This part of Kashmar ـ Kerman tectonic zone has good potential for Kiruna ـ type deposits and should be designed detailed exploration schedules for it.
