『Abstract
It is shown that terrigenous apatite in soil, weathering crusts,
and low peat bogs of humid zones is transformed into hydrogenous
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.』
