Copper mineralisation occurred at 2.5 km south of Veshnoveh village, about . 60 km south of Qum, were studied in this paper. The
host rock of mineralisation is trachybasalt and trachyandesite in association with pyroclastic rocks of upper Eocene age. The paragenetic sequence consists of, chalcocite, native copper, bornite, coveline, chalcopyrite, pyrite and hematite. The main gangue minerals are calcite, chalcedony, chlorite, epidote, microcrystalline quartz and zeolite group minerals. The textural features, phase stability and microthermometric investigation, indicated that the copper mineralisation has been occurred at 200° C. The main characteristic features of the copper mineralisation at Veshnoveh are similar to those f “Copper Mantos” deposits.
