摘要内蒙古朱拉扎嘎金矿床是一个低品位、规模大，并具有细脉-微细脉浸染和蚀变特征的金矿床.矿床赋存于中新元古代沉积变质岩中，受层间破碎带的控制.矿石矿物组成有金属硫化物石英、长石，少量方解石、黏土矿.金以晶隙金为主，成矿溶液主要来自岩浆热液活动，成矿温度平均在286℃，成矿物质来源既有赋矿地层的提供，也有深部物质的参与.该矿床在成矿地质背景、赋矿岩石、矿化形成、矿物组合和成矿作用等方面均与穆龙套型金矿床具有可对比性.

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.

Key words： gold deposit metallogenic characteristics Muruntau type Zhulazaga Inner Mongolia
