摘　　要：青海石头坑德是近年来发现的镍矿床,赋矿岩石为辉长岩、辉石岩相和橄榄岩相;矿石金属矿物主要为磁黄铁矿、镍黄铁矿、黄铜矿、黄铁矿、磁铁矿。矿石主要为交代粒状结构,海绵陨铁状,块状构造。该文中对石头坑德镍矿床和夏日哈木超大型镍矿的主要岩石矿物组合和矿石矿物组合作了比较,表明石头坑德镍矿具有形成大型-超大型规模矿床的有利条件。The Shitoukengde Ni deposit in Qinghai is confined to gabbro, pyroxenite and peridotite. Main ore minerals are pyrrhotite, pentlandite, chalcopyrite, pyrite and magnetite. The ores have granular metasomatic texture, sideronitic texture and massive structure. This paper compares mineral assemblage of the Shitoukengde Ni deposit with that of the superlarge Xiarihamu Ni deposit, considering the Shitoukengde Ni deposit might be a superlarge one.
