摘　　要：羟铟石(Jalindite)产在云南个旧马拉格锡石—多金属矿床氧化带中,是一种铟的次生矿物。镜下观察白色透明,均质体。折光率1.725±0.002,ao=7.9514×10-7mm。主要粉晶谱线(nm):0.395(10),0.279(8),0.178(10),0.163(8),0.1325(7),0.1260(7),0.1200(8),0.1065(10)。电子探针8个测试点平均含铟69.34%。元素分析含H1.78%,计算OH30.26%,不含C、S、N。矿物成因和实验研究表明,羟铟石中铟来源于原生硫化物矿物。铟在氧化铁矿石中主要呈独立矿物,其他形式均占极次要地位。Dzhalindite, a secondary mineral of indium, occurs in the oxidized zone of Malage cassiterite-polymetallic ore deposit, Gejiu county, Yunnan province. It shows white, glassy luster, and transparency. Under the polaring microscope, it has colorless, homogeneity, Nmeas=1.725±0.002, and ao=7.9514. The strongest diffraction lines dfrom the x-ray power diffraction data are 0.395(10), 0.279(8), 0.178(10), 0.163(8), 0.1325(7), 0.1260(7), 0.1200(8), and 0.1065(10)nm. The average composition (%) of Dzhalindite is In 69.34, H 1.78, O 28.48, and with totaling 99.60. The mineral genesis and the empirical researches are suggested that indium in Dzhalindite came from the primary sulphide mineral. Indium mainly occurs as independent minerals, and less as other types in the ferric oxide ores.
