Mineralogy of the sulfate-sulfide mineralizations at the Garus District; NW of Iran Mineralogía de las mineralizaciones sulfato-sulfurosas del Distrito Garus, NW de Irán (original) (raw)

There are some vein type sediment hosted sulfate-sulfide mineralizations in Garus district, NW of Iran. They occur in a (shale) host rock of Precambrian age and they show evidence of some deformation. The field, microscopic, XRD and SEM-EDS techniques were used in this investigation. Mineralogical, the veins are composed of barite (Sulfate phase), galena, chalcopyrite, covellite (main sulfide minerals) and dolomite, ankerite, quartz, cerussite, anglesites', calcite, goethite as gangues. Microscopic and XRD investigations indicated the presence of more than 15 minerals at Garus. The SEM-EDS assessments show some probable minor phases present in the investigated galenas. Field and microscopic investigations show barite formed earlier than the sulphide mineralization. The objective of this research is to reveal the new horizons in the mineral exploration in NW of Iran. Resumen Existen algunas mineralizaciones de sulfatos y sulfuros que albergan venas de sedimentos en el distrito Ga...
