Abstract

Chahar-Gonbad copper mine, in Kerman province, has mainly formed as veins with low reserves and medium grade. Mineralization is mainly occured as chalcopyrite, PYRITE, rare galena and sphalerite. Sericitic, argillic and propylitic alterations have been identified in this are deposit. This alteration occurred in the thermal range of about 350oC. In this research, the MORPHOLOGY of PYRITE crystals is used for determination of the thermal range of mineralization. It is possible that the PYRITE form in a mineralization zone shows the state of thermal range during mineralizaton. Based on this assumptian, the needle crystals are formed in TEMPERATUREs below or equal to 250oC, abundant grooves while with increasing TEMPERATURE to 450oC the cubic crystals with abundant grooves and a few octahedral surfaces are formed. Investigations of collected PYRITE crystals from alteration zones of this ore deposit show that the cubic types with abundant pyritohedron surfaces are common and crystals with high density with groove surfaces are seen with smooth surfaces crystals. Therefore it is interpreted that PYRITEs have formed in the thermal range between 250 to 450oC. According to the TEMPERATURE range for alteration (mean 350oC), it seems copper that the mineralization have occurred between 350 to 450oC.
