| Abstract: | It is shown that terrigenous apatite in soil, weathering crusts, and low peat bogs of humid zones is transformed into hydrogenous forms and solutions. In arid environments, apatite is transported to terminal discharge basins and transformed within diagenetic mud. Continental blocks are the main source of phosphorus in epicontinental and marginal seas. It originates from two sources (continents and seawater) in oceans. The role of biogenic factor in phosphorus geochemistry is significant, variable, and manifested at different stages of phoshogenesis. |
