Iron oxide-copper-gold mineralization of the Devonian Laoshankou deposit (Xinjiang, NW China) in the Central Asian Orogenic Belt

The Laoshankou Iron Oxide-Cu-Au (IOCG) deposit (41 km southwest of Qinghe City, Xinjiang, NW China) is the most important magnetite deposit with economic Cu and Au (metal reserve: 3.26 Mt Fe @ 33.5–36.4%, 9.8 kt Cu @ 0.2–0.4% and 0.14 t Au @ 0.5–1.3 g/t) in the East Junggar terrane of the Central Asian Orogenic Belt (CAOB). The deposit is hosted by volcanic rocks of the Middle Devonian Beitashan Formation. In this study, four hypogene...
