最近,通过对内蒙白云鄂博西矿物质成份的研究,在岩心人工重砂样品中发现了褐铈铌矿、褐钇铌矿及其中间变种钇褐铈铌矿。 褐钇铌矿-褐铈铌矿族矿物的组合特征,是白云鄂博矿区所特有的。1964年在该矿区东部接触带发现了与硅镁石、金云母、铈磷灰石、方解石及烧绿石等共生的褐铈铌矿。这次钇褐铈铌矿的发现,在我国尚属首次。 本族矿物Nb_2O_5的含量高达40％以上,仅低于铌铁矿、铌钙矿、烧绿石等少数几种富铌矿
Recently, the mineral composition of Baiyunebo West in Inner Mongolia has been studied. In the sample of core heavy sand, the cerous niobium ore, the brown yttrium niobium ore and its intermediate species yttrium ceritizenimite were found. The combination of the brown yttrium-niobium-ceronitic-niobium mineral is characteristic of the Bayan Obo mine. In 1964 in the eastern contact zone found in the mining area and steatite, phlogopite, cerial apatite, calcite and pyrochlore and other co-occurrence of cerium niobium ore. The discovery of this yttrium-cermet niobium ore is the first time in our country. The mineral Nb_2O_5 content of more than 40%, only less than niobite, niobium ore, pyrochlore and a few other kinds of rich niobium ore
