Abstract
The recent concepts on the processes of marine phosphorite genesis are discussed. Modern and ancient phosphorites show significant differences in facies and paleogeographic aspects. The most important factor for phosphorite formation is the process of replacement of biogenic material by phosphate, which to a certain degree allows matching the hypotheses of phosphorite genesis in spite of the difference in the geologo-mineralogical and structural parameters of marine phosphorites.
