磷灰岩由于铀含量高(5—600×10~(-4)%),因而与其他类型的沉积岩可明显地区分开(1963)。关于磷灰岩中铀聚集的控制因素问题在许多著作中都进行了讨论(等,1966;1970)。但是,磷灰岩中铀含量大
Phosphourites are clearly distinguishable from other types of sedimentary rocks due to their high uranium content (5-600 × 10 -4%) (1963). The control of uranium accumulation in phosphorites is discussed in many books (1966; 1970). However, the phosphorite contains a large amount of uranium
