阴山中元古代成矿带（狼山渣尔泰山）属于华北地台元古宙巨大成矿带的西段，产有多处硫铁多金属矿床，一些已经达到超大型矿床的规模。它们形成的时代和地质环境具显著的热水沉积成矿的特征，可与世界中元古代ＳＥＤＥＸ对比。已经判别出成矿盆地及热水通道等。充足的物质来源、巨大的热源、热水系统演化的完整性、成矿盆地极好的封闭性保证了同生期成矿的高强度，造山期的后生作用也有明显叠加改造作用 The Middle Paleoproterozoic metallogenic belt (Langshan-Zhaltai Mountain) of Yinshan belongs to the western segment of the huge Proterozoic metallogenic belt in the North China Platform. There are many iron-iron polymetallic deposits and some of them have reached the scale of super-large deposits. They formed the era and geological environment with significant hydrothermal sedimentary mineralization features, with the world of Mesoproterozoic SEDEX contrast. Has identified a metallogenic basin and hot water channel. Adequate material source, huge heat source, the integrity of the evolution of hot water system, and the extremely good confinement of the metallogenic basins ensure the high intensity of metallogenesis during the same age. The epigenetic effects during the orogeny also have significant superimposed and reworking effects
