摘　　要：安徽省皖北地区发现的原生金刚石,不同于之前在砾岩和松散沉积物中发现的金刚石,其载体也既不同于国内已发现并开采的原生金刚石矿床之金刚石载体,也不同于世界上其他国家发现并开采的原生金刚石载体。之前在砾岩中或在第四系松散沉积物发现的金刚石大小混杂,颜色多样;国内及世界上已开采的原生金刚石矿床,其载体基本上均为金伯利岩或钾镁煌斑岩,尤以前者为主。而安徽皖北地区发现的原生金刚石,其载体为橄栏玄武岩、玄武质角砾熔岩、火山角砾岩和辉绿岩。The primary diamonds found in the Wanbei area of Anhui Province are different than those unearthed before in conglomerate and loose sediments that are mixed in size and color,and their carriers are also distinctive from those from the known and producing primary diamond ore deposits at home and abroad that are kimbolites or lamproites,mostly the former.The primary diamonds found in the Wanbei area,Anhui are hosted in olivine basalt,basaltic breccia lava,volcanic breccia and diabase.
