摘　　要：三道庄和黄背岭矿区矽卡岩、用岩的对比研究显示出，矽卡岩和角岩各元素丰度和配分型式主要取决于原岩的岩性，其次与交代热液性质和交代程度有关。不同矿区的砂卡岩具有不同的元素组合，这些元素组合对矿床形成和矿化规模有一定影响。Comparative investigations on skarns and hornstones from Sandaozhuang and Huangbeiling indicate that the abundances and distribution patterns of rare-earth elements in these rocks chiefly depend on the composltion of their source rocks as well as on the nature of hydrothermal fluids and metasomatic degree. Skarns in different deposits have different element assemblages. These assemblages have certain implications for the formation and scale of ore deposits.
