摘　　要：津巴布韦大岩墙于太古代晚期侵入津巴布韦克拉通内,形成了现在的南北段5个次级岩浆房的格局。利用对大岩墙主含矿层-主硫化物带的地球化学分析结合野外地质资料,总结了该矿床的特征并分析了成因,认为形成矿床的原始岩浆来源于地幔深处,于太古代晚期上侵至现在的位置发生结晶分异作用而形成了现在的矿床。The Great Dyke of Zimbabwe intruded into Zimbabwe craton in late Archean, formed the present structure of five secondary magma chambers located in north and south sectors. Based on the geochemical analysis on the primary ore-bearing beds and sulfide zone and in combination with field geological data, the authors summarized the characteristics and origins of Pt-Pd ore deposit, regarded that the primitive magma of the deposit was derived from the deep mantle, intruded up into the present location in late Arehean, formed the present deposit through crystallization and differentiation.
