Abstract :

The study erea is located in weast of Arghash mine. Totale composation Intrusive bodies is diorite until granodiorite. Alteration zones consists of, propylitic, sericitic, argillic, silicified and carbonate zones. In this erea mineralization consist of vein type and disseminated mineralization. vein type mineralization in relation with fault zones and consists of pyrite, magnetite, sphalerite, galena, calcite and quartz. desseminated mineralization consist of pyrite, chalcopyrite and magnetite. from weathring of the hypogene mineral has generated hug surficial amounts of supergen mineral wiche of malachite, azurite, limonite, hematite and goethite. Geochemical Exploration in erea has done considerd based on stream geochemical and litho geochemical and has measard value Cu, Pb, Zn, Sb, Mo, and Fe. in stream sediments maximum value of Cu ٧١ ppm, Pb 47 ppm, Zn 155 ppm, Sb 31 ppm , Fe 100000 ppm and Mo <1 ppm. in litho samples are value Cu 21000 ppm, Pb 19000 ppm, Zn 14000 ppm, Sb 522 ppm , Fe 54000 ppm and Mo <1 ppm. presence of intrusive bodies and sub volcanic with acid until intermediate composation, presence propylitic, sericitic, argillic, silicified and carbonate alteration zones associate with vien type mineralisation in fault zones and disseminated mineralization in arghash erea indicate possible vein type mineralization in relation to copper porphyry system.
