摘　　要：文章对产于津巴布韦大岩墙内的哈特利(Hartley)铂矿床的地质特征和成因进行研究。津巴布韦大岩墙于新太古代侵入,在津巴布韦克拉通内形成南北段次级岩浆房格局。哈特利铂矿的铂族元素主要分布在杂岩体的中下部,与硫化物密切相关,主要含矿矿物为铋、碲矿物。在岩浆侵位的过程中发生结晶分异,形成了铂族元素和硫化物的垂向分带。哈特利矿床与中国金川等铂族元素矿床相比,其成岩成矿时代早,矿床特征、成矿元素组合方面均有明显不同。In the paper are studied geological characteristics and genesis of Hartley platinum deposit in the Great Dyke,Zimbabwe.The dyke intruded in Zimbabwe craton in Late Archean and is divided into the north and south subchambers.PGE of the deposit is mainly distributed in the middle and lower part of the Hartley complex and closely related to the sulfide.Bismuth,tellurium minerals are the main ore mineral.During emplacement crystallization differentiation resulted in vertical zoning of PGE and sulfides.Compared with Jinchuan ore deposit in China Hartley platinum deposit is quite different in aspects of age,geological characteristics and ore-forming element combination.
