Mineralization and Ground Magnetic Survey for Mineralization Prospecting and Identify of Intrusive Bodies in the Neyshabour Firoozeh Mine, Khorasan Razavi


Geology department, Ferdowsi University of Mashhad


     The study area is located in Middle Eocene to Mio-pliocene plutonic-volcanic belt in northwest of Neyshabour in Binaloud structural zone. The most important rocks cosist of lava and pyroclastic as trachyte and andesite of Eocene which affected by subvolcanic intrusions. Alterations include silicic, argillic and carbonate which affected the extrusive and intrusive rocks of the area. The mineralization contains of magnetite, specularite, pyrite, chalcopyrite, bornite, hematite, alunite, covellite, turquoise and limonite. The texture of mineralization mainly includes dissimination, stockwork, vein, veinlet and hydrothermal breccia. In order to determine depth and extension of the magnetite mineralization associated with sulfide ores, and expansion of productive intrusive bodies, ground magnetic survey was performed. According to the data processing of ground magnetic, the actual location of anomaly is the east and southeast of district and is accordance with the alteration and mineralization of district, indicating the effect of anomaly from surface to depth and a big IOCG mineralization has been occurred in the Neyshabour Firoozeh mine.
