Abstract The Zhulazaga gold deposit in Inner Mongolia is characterized by large reserves, low grade and intense alteration and dissemination of veinlet and micro-veinlet. The deposit occurs in the Meso-Neoproterozoic sedimentary metamorphic rocks, controlled by interlayer fracture zones. Sulfides are the dominant ore minerals, with quartz, feldspar and minus calcite and clay minerals. The gold is mainly of intercrystalline. The ore-forming fluid is derived mainly from magmatic hydrothermal activities, with average temperature of 286℃. The ore materials are originated mainly from the host strata and partially from the deep. As for its geological setting, ore-hosting rock, metallogenesis and mineral assemblage, the Zhulazaga gold deposit is comparable with the Muruntau gold deposit.
