Samarskite 是以苏联矿山工程师萨马尔斯基命名的稀土、铀、铁等钽铌酸盐类矿物。由于该矿物化学组成极复杂、成分变化大,且常呈非晶变态, 因此该矿物便成了矿物学研究的“难题”。自从自然界发现了结晶态的 samarskite 后,此矿物的矿物学研究,才从根本上获得解决。不过,迄今人们对其知之不多,或知之甚谬, Samarskite is a rare earth, uranium, iron and other tantalum niobate mineral named after Samarrski, a Soviet mine engineer. Due to its complex composition, large compositional variation, and often amorphous metamorphism, the mineral has become a “problem” in mineralogy. Since the discovery of crystalline samarskite in nature, the mineralogy of this mineral has been fundamentally solved. However, until now, people have little or no understanding of them.
