某伟晶岩体含有钽铌铁矿、铌钽铁矿、重钽铁矿、钽锰矿、锡钽锰矿五种铌钽矿物,需要对该岩体的不同带定量测定这五种矿物的含量,以研究其成因。这五种矿物都呈黑色,根据矿物的光性及物性在显微镜下难以区分开,也不能准确地测定这五种矿物的含量。对于物相分析,也很难选择出合适的溶剂将这五种矿物各自分离开来进行测定。本工作是采用激光显微光谱分析手段试验出这五种矿物的光谱特征,依此将它们区分开
One pegmatite body contains tantalum-niobite iron ore, niobium tantalite iron ore, heavy tantalum iron ore, tantalum manganese ore and tantalum manganese ore five kinds of niobium tantalum minerals, which need to be quantitatively determined for these five minerals in different zones of the rock mass, To study its causes. All five minerals are black and can not be accurately determined by microscopic examination of the light and physical properties of minerals. For phase analysis, it is also difficult to select a suitable solvent to separate the five minerals were measured. In this work, the spectral characteristics of these five minerals are tested by means of laser micro-spectroscopy to distinguish them
