有关白云鄂博铁稀土矿床中稀土元素的组成特点和赋存形式,我所在六十年代曾作了大量工作,积累了大批数据。本文主要是利用这些数据,对该矿床中的稀土元素特别是其中的Nd、Sm、Eu的分配特点作初步阐述。 一、各类矿石中Nd、Sm、Eu含量与稀土总含量的关系 将包括主东矿及其上下盘,西矿和东部接触带的十六种矿石及各种产状的氟碳铈矿,独居石,易解石和氟碳钙铈矿的平均稀土总量和分量,∑(La、Ce、Pr),∑(Nd、Sm、Eu)
Regarding the compositional characteristics and occurrence patterns of rare earth elements in the Baiyunebo iron-bearing rare earth deposits, a large amount of work was done in the 1960s and a large amount of data have been accumulated. The main purpose of this paper is to make use of these data to preliminarily describe the distribution characteristics of rare earth elements, especially Nd, Sm and Eu in the deposit. First, all kinds of ores Nd, Sm, Eu content of the total content of rare earth will include the main East Mine and its up and down plate, West Mine and the eastern contact with 16 kinds of ore and bastnaesite of various origin, Σ (La, Ce, Pr), Σ (Nd, Sm, Eu) and the average rare earth contents and compositions of monazite, calcite and bastnasite,
