title: Main Patterns of Geochemistry of Phosphorus
abstract: The paper presents the main conclusions of the Russian monograph “Geochemistry of Phosphorus” (2020). Based on statistical processing of ~6100 sample averages (from ~190,000 analyses), new estimations of World averages (Clarke values) for Р2O5, % (and P, %), phosphorus-titanium module (P2О5/TiO2), phosphorus-calcium module (P2O5/CaO), phosphorus-iron module (P2О5/Fe2O3), and phosphorus-total iron module (P2O5/Fe2O3 + FeO). Many estimates have been made for the first time. In addition to the new
