Abstract

Among the sandy phosphorites of the U.S.S.R., series of genetic structures have been discovered which decipher to a certain extent the mechanics of the accumulation of phosphates. These structures have been observed in all the phosphorites examined from the various geologic systems and from different parts of the country. The degree of facility of phosphatization was ascertained for different intervals. The chemical constitution of the phosphorites examined has no resemblance whatever with known phosphate minerals.
