Abstract A carbonatite sample from Phalaborwa, South Africa, consists of apatite, magnetite and a calcite - dolomite 'perthite' which is interpreted as being due to exsolution of dolomite from a high-Mg calcite precursor. Carbon and oxygen isotope data indicate that the carbonates are equilibrated. In situ ion- microprobe analyses for Fe, …
