The formation of a reaction rim around picroilmenite from kimberlite was studied by means of experimental and numerical modeling. em. The replacement of picroilmenite gave rise to chemical zoning in the ilmenite matrix ...
Deep-seated xenoliths in kimberlites are traditionally subdivided into granular low-temperature and deformed high-temperature groups. Recently, the rare element geochemistry of rocks and minerals has been invoked more often ...
