| Abstract: | Different hypotheses of phosphorite formation are discussed. The biogenic origin of phosphorites is most plausible. The important role of terrigenous material in P2O5 migration and concentration in the hypergenesis zone is emphasized. The mineralogical zoning of phosphate accumulations is described and the probable diagenetic alteration of accessory apatite in present-day seas and lakes is affirmed. |
