PHOSPHORUS HYDRIDES AS MAIN MIGRATION FORM OF PHOSPHORUS

Phosphorus hydrides are formed in a H-rich, reduction environment. Research on mineral components of meteorite and moon rock, composition of phosphorus minerals from endogenetic deposits, characteristics of phosphorus-accompanying minerals and existence of a large mount of H in Earth argue all for a conclusion that phosphorus deposits may be attributed to the migration of phosphorus taking a form of phosphorus hydride by magma, hydrothermal solutions and gas to shallow regions of the crust where, owing to decrease in pressure, low in temperature, increase in oxygen fugacity and Eh value, and H2-escape, the phosphorus hydrides began oxidation and resolution so as to form phosphorus minerals which, afterward, enriched into a deposits after going through superposition a series of geological events.
