Abstract: (1242 Views)
Arc copper mine is located about 55 km northwest of Birjand city in South Khorasan Province. The rock units at this area include thin to medium-bedded flysch sandstones in red and gray colors with Eocene age. Copper mineralization occurred in the upper part of bleached gray sandstones in a lenticular shape. There are at least two revitalization beds. Each of the horizons consists of three zones: Red Zone, Bleached Zone, and Mineralized Zone.The mineraliztion zone has occurred within the bleached and reductant zone. The texture in this deposit is replacement and scattered grains. The presence of framboidal pyrites in the ore horizons and the intactness of cellular structures replaced by sulfides indicate that this deposit was formed during the early stages of diagenesis prior to deep burial. Based on lithology (host rock from sandstone greywacke to litharnite), mineralogy of mineral (chalcocite, covelite), structure and texture, stratigraphy and factors controlling mineralization (presence of traces and remains of plants as the main factor regenerative environment, appropriate permeability of the host rock) suggest that this deposit is the similar to Red Bed type sedimentary copper deposits.
