Phosphorus speciation data from geological samples of the Archean Moodies Group and from laboratory experiments

The data include P speciation data (reduced and polymerized P) from Archean rocks in the Moodies Group in South Africa (3.2 Ga), spanning across basaltic intrusions into sedimentary strata, as well as experimental data from simulations of phosphate heating in the presence of organic matter and iron as would have occurred during magma intrusions. Also included are auxiliary geochemical data of bulk elemental abundances to characterize the rock samples.
