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 Clarke estimates,
sometimes very different from previous ones, the work carried out has led to a number of new conclusions. In
particular, the titanium geochemical
barrier for phosphorus has been first estimated, all the 11 genotypes of
phosphogenesis have been named and characterized, five genetic correlations of
phosphogenesis have been described, lithochemistry methods have been
successfully applied to characterize the phosphorites. Due to the large breadth
of generalization, the monograph has a large theoretical and applied value.
