众所周知,在不同成因的磷灰石族矿物中经常见到铀的混入物[3]。关于该元素与磷灰石的结合形式,马克格利维和湼利松[5]的假定得到了推广。根据这种假定,铀参与在矿物晶格中,类质同象地取代其中的钙,由于四价铀和钙的离子半径很近似,故在理论上是完全可能的。但是,这一概念[4、8、9]未经实验所证实。对于研究少量稀有元素与含有稀有元素矿物的结合形式.罗日科娃建议采用电解法[7]。罗 It is well-known that uranium inclusions are commonly found in apatite minerals of different origin [3]. With regard to the combination of this element with apatite, the assumptions of Mark Greeley and Nerlsson [5] have been generalized. Based on this assumption, uranium participates in the replacement of calcium in the crystal lattices in a metacentric manner, which is theoretically possible since the ionic radii of quaternary uranium and calcium are very similar. However, this concept [4,8,9] has not been experimentally proven. For the study of a small number of rare elements and the combination of rare earth elements containing minerals. Luo Nikko proposed electrolytic method [7]. Luo
