Abstract:Located in the Boluoke'nu metallogenic belt of the West Tianshan Mountains in Xinjiang, the newly discovered Halegati-Muzuke Fe-Cu-Pb-Zn deposit is a medium-sized skarn deposit, and may potentially become a large one. The orebodies occur at the contact zone between Dawabulake pluton and marble, marbleized limestone of the Upper Ordovician Hudukedaban Formation. Orebodies are controlled in trinity by the pluton, strata and structure of the contact zone. Dawabulake pluton consists mainly of monzogranite and granodiorite, and is rich in Si, Al, K, Na, LILE, and poor in Mg, HFSE. The pluton is I-type granite and has the magma characteris- tics of subduction zone. The carbonates of Hudukedaban Formation(O3h)are rich in Cu and Zn, which is favorable for mineralization through hydrothermal metasomatism, and hence this horizon is likely to become a favorable formation for regional prospecting. As a geochemical barrier and a pathway of hydrothermal fluids, the structure of contact zone controls the skarn orebodies.
