苏联科学院矿物学、地球化学和稀有元素結晶化学研究所的波利申科和李祖諾夫新近研究了钪和某些稀有元素在錫石中的存在状态。並在該院的“地球化学”杂志1959年第1期中发表了他們的研究成果。研究的对象,包括苏联52个矿床和国外22个矿床的錫石,作了300个以上的錫石样品分析。研究钪和铌的方法,主要採用光譜定量分析法:分析时挑选純淨的錫石,鑑定钪和铌的灵敏度为0.001％(以金屬計算)。鑑定的精确性为±10％。研究的結果,得出如下的結論: 1.高含量的钪(可达0.2％Sc_2O_3)主要存在于云英岩型矿床的錫石中。在偉晶岩型和硫化物——錫 Polyshenko and Lee Zunov, Institute of Mineralogy, Geochemistry and Rare-Earth Crystals Chemistry, Soviet Academy of Sciences, recently studied the existence of scandium and some rare elements in cassiterite. And published their findings in the 1959 issue of Geochemistry, in the hospital. The research object, including the Soviet Union 52 deposits and 22 deposits of cassiterite, made more than 300 samples of cassiterite. Scandium and niobium research methods, the main use of quantitative spectroscopy: Analysis of the selection of pure cassiterite, scandium and niobium identification sensitivity of 0.001% (in terms of metal). The accuracy of the identification is ± 10%. The results of the study draw the following conclusions: 1. High content of scandium (up to 0.2% Sc_2O_3) is mainly found in cassiterite-type deposits. In the pegmatite type and sulfide - tin
