Abstract

The HIRED GOLD MINERALIZATION is located in 140 km SW of BIRJAND in Lut Block. This area consist of Jurassic shale and sandstone units, upper Cretaceous shale, conglomerate, sandstone, marl, lime tuff and sandy limestone, Paleocene and Eocene volcanics and pyroclastics and Neogene young volcanics. Reduced subvolcanic granodiorite to quartz diorite with post Eocene age and porphyry texture intruded the Eocene volcanics and pyroclastice units, and caused alteration and GOLD MINERALIZATION. The mineralization divided into three parts in the HIRED GOLD MINERALIZATION: INTRUSION-HOSTED DEPOSIT, PROXIMAL DEPOSIT and DISTAL DEPOSIT. The three parts are different in host rock, mineralogy, alteration, structure and texture and metal assemblage. The HIRED GOLD MINERALIZATION contain metal anomalies Au, As, Ag, Zn, Pb, Cu, Sb, Sn, W. paragenesis of This mineralization include arsenopyrite, pyrite, pyrrhotite, sphalerite, galena, chalcopyrite, bornite, tetrahedrite and bismutenite, accompaniment with biotite, sericite, carbonate and silica alteration. HIRED GOLD MINERALIZATION on the basis of tectonic setting, type of intrusions bodies, paragenesis, alteration, metal anomalies and structure and texture can be regarded as a deposit related to REDUCED GRANITOID intrusions.
