1962年夏,766地质队在普查铌钽矿床时,曾于区内某冲积砂矿中发现一种黑色板状未知矿物,我们经过室内研究,确定它为一种较罕见的富含铀与钇族希土的钽铌酸盐类矿物——铌钇矿。对铌钇矿及含该矿物花尚岩的进一步研究尚在进行中,兹先将有关资料作一初步报导。一关于铌钇金乙矿的主要鉴定结果本矿物——铌钇矿(Samarskite,),虽产于砂矿中,但晶形保存完好,多呈板状、薄板 In the summer of 1962, during the census of the niobium-tantalum ore deposit, the 766 geologic team discovered a black plate-like unknown mineral in an alluvial sandstone in the area. After an in-house study, we determined it to be a rare rare earth element rich in uranium and yttrium Tantalum niobate mineral - niobium yttrium ore. Further studies on the yttrium-yttrium ore and the rock containing this mineral are still underway. We will first make a preliminary report on the data. The main results of the identification of niobium-yttrium gold-copper ore The mineral-yttrium ore (Samarskite), although produced in the sand, but preserved crystal form, mostly plate-shaped, thin plate
