氟碳铈钡矿产于白云鄂博铁铌稀土矿床中。1965年发现于西矿区。贵阳地球化学所稀有矿物研究组(1972)和彭志忠、沈今川等(1980)及后来李方华等对该矿物进行了矿物学研究。本文报道了采自东矿区几个样品的分析测定结果。 一号氟碳铈钡矿(样品编号:东1606),产于东矿体靠近上盘的钠辉石型矿石中,与钠辉石、萤石、重晶石等矿物共生,矿物呈粒状或板状,大小不一,集合体大者直径可达数毫米。桔黄色或密腊黄色,玻璃光泽或油脂光泽,一组解理{30(?)}不完全,断口不平坦。用
Bastnasite bastnasite is produced in the Bayanobo iron-niobium rare earth deposit. Found in 1965 in the West Mining District. The mineralogy study was conducted by the Group of Rare Mineral Studies (1972) and Peng Zhizhong, Shen Jinchuan et al. (1980) and later by Li Fanghua, Guiyang Geochemistry Institute. This paper reports the results of the analysis of several samples taken from the East Mine. No. 1 bastnasite (sample number: East 1606) is produced in the sodium ore of sodium pyroxene near the upper ore body in the east ore body and coexists with minerals such as sodium pyroxene, fluorite and barite. The minerals are granular or Plate-shaped, different sizes, the largest assembly of up to several millimeters in diameter. Orange or dark yellow, glassy or greasy, one set of cleavages {30 (?)} Incomplete, fracture not flat. use
