摘要
本文对山西、河南、四川等地某些铝土矿中稀土元素的分布、配分、比值及其含矿岩系与基底岩石、古陆花岗岩和变质岩中稀土成分的相关系数作了对比研究.据此探讨了铝土矿的物质来源.
The distribution cf REE and thier ratios for some aluminmun deposits in Shanxi, Henan and Sichuan were investigated. In addition, for the rare earth components in ore-bearing rock series and basement rocks, and in palaeocontinental granite and metamorphic rocks, comparative studies on their correlation coefficients were made respectively. In the light of these studies, the problem on the source material of aluminium deposits is discussed in this paper.
