摘　　要：矿体赋存在上泥盆统坦盖塔尔组上段碎屑岩向碳酸盐岩过渡部位,具有双层结构。矿石组构具有明显的热水沉积成因特征,研究表明:矿床成矿物质主要来源于深部寒武-奥陶系的基底地层。矿床系下渗的海水和大气水混合淬取了基底丰富的成矿物质形成上升热卤水在海盆中喷流沉积而成。The orebodies occur in the transition part of the upper Devonian Tan'gaitaer group upper part clastic rock to carboniferous rock with two-layer structure. The ore fabric shows obvious genetic characteristics of hydrothermal deposition. The research indicates that ore forming matter mainly origin in beasement strata of Cambrian-Ordovician system. The deposit was formed by the mixing of leaking sea water with meteoric water that extracted plenty of ore matter from the basement to form ascending hot brine and was deposited in spout in the sea basin.
