dc.description.abstract	The analysis of geotectonic settings and the planetary distribution of phosphate ores revealed that apatite deposits are confined to the continental rift zones with the uplifted Moho discontinuity, while phosphorite deposits are developed on ancient continental shelves, which mark upwelling zones in the paleooceans that received phosphorus during the oceanic crustal spreading. It is established that the formation of economic phosphate deposits in the Panerozoic corresponds to epochs of intense planetary tectonic and volcanic activity, which also emphasizes the substantial role of endogenic phosphorus in phosphorite accumulation. It is shown that the accumulation of phosphate ores on continents and in oceans was synchronous. Large phosphorite reserves accumulated during particular epochs correspond to insignificant apatite ore reserves and vice versa.
