| Abstract: | Fe-Cu-polymetallic skarn deposits in the Qimantage area of western Qinghai Province are widely distributed. Two main skarn deposits are developed, i.e. calcic and manganoan skarns, however, in a few deposits, there are also magnesian skarn. The constitute minerals of the calcic skarn are mainly diopside, hedenbergite, grossular, andradite, epidote, actinolite and scapolite. Their associated mineralizations are usually Fe, Cu, and Mo, while for manganoan skarn are chiefly Mn-hedenbergite with minor pyroxmangite, associated with Pb, Zn and Ag mineralizations. The magnesian skarn is made up of diopside, forsterite, monticellite, and phlogopite, associated only magnetite and ludwigite. So the skarn types may distinguish the different metallic associations in the skarn deposits of the Qimantage area, Qinghai Province. |
