The phosphorus cycle, phosphogenesis and marine phosphate-rich deposits

Marine sedimentary phosphate deposits are particularly suited to study aspects of the phosphorus cycle, because, in the case of ubiquity, their origin may result from a general acceleration of the global phosphorus cycle. Sources of sedimentary phosphate are microbial breakdown of buried organic matter and redox-driven phosphate desorption from ...
