海相沉积岩系中铀与磷的关系的研究报道并不很多。一般认为在海相含磷岩系内铀的富集与磷有一定的共生关系。如铀和稀土元素呈类质同相杂质存在于磷块岩中,其聚集取决于磷酸盐的结晶化学性质。作者在某地磷块岩中见有铀的同生聚集和后生聚集的不同实例。这些现象似乎表明在含磷岩系中铀、磷的关系不是那么简单的。下面介绍对某地早寒武世初期含磷地层中铀与磷的关系的初步认识。所研究的地区位于康滇古陆东侧,早寒武世初期为浅海海洼沉积区,形成一套自下而上为泥质碳酸盐,硅质、
There are not many reports on the relationship between uranium and phosphorus in marine sedimentary rock series. It is generally believed that enrichment of uranium in phosphorus-bearing marine rocks has a symbiotic relationship with phosphorus. Such as uranium and rare earth elements are similar to the existence of homogeneous impurities in the phosphorite, its aggregation depends on the crystallization of phosphate chemistry. The authors found different examples of syngenetic and epigenetic aggregation of uranium in some phosphorites. These phenomena seem to indicate that the relationship between uranium and phosphorus in phosphorus-bearing rock series is not that simple. The following is a brief introduction to the relationship between uranium and phosphorus in the early stage of the Early Cambrian phosphorus-bearing strata. The area under study is located on the east side of the Kang-Dian ancient land. Early Early Cambrian was a sedimentary area of shallow sea and seawater, forming a set of bottom-up argillaceous carbonate, siliceous,
