Phosphorus speciation data from cherts and spherule beds related to the S2 impact event 3.2 billion years ago in South Africa

The data include total phosphorus abundances and concentrations of oxidized (phosphate) and reduced phosphorus (phosphite) for a series of samples spanning the S2 meteorite impact event recorded in the Barberton Greenstone Belt in South Africa at 3.2 billion years ago. The data explore the effects of impacts and hydrothermal silicification on the phosphorus redox cycle in the Archean.
