Abstract :

Chahshaljami exploration area is located in the Southern Khorasan and belongs to the Lut Block volcanic-plutonic belt. Oligocene subvolcanic granitoids intruded in Eocene volcanic-volcaniclastic sequences. Alteration minerals include Alunite, Jarusite, Chlorite, Dickite, Sericite, Montmorillonite, Quartz and Iron Oxide. Mineralization includes pyrite, arsenopyrite, Molybdenite, Chalcopyrite, Sphalerite, Galena and enargite. High temperature-salinity of Fluid inclusions from sericite alteration is an indicator that can direct the next exploration toward the mineralization center. Temperature-salinity of Fluid inclusions decrease toward the vuggy quartz alteration witch indicate the increase of the role of meteoric fluids. Geological, alteration, mineralization and hydrothermal fluids evolution evidences indicate the highsulfidation epithermal mineralization related to the deep porphyry system in the area.
