Popis: Samples originating from the UG-2 of the Bushveld Igneous Complex, South Africa, contain varying amounts of chromite. Most laboratories, including the Pretoria University’s Facility, use the current Powder Diffraction File (PDF) maintained by the International Centre for Diffraction Data (ICDD), for the qualitative data interpretation. The chromites that show the closest fit to that of UG-2 chromite, do not resemble its chemical composition. In this paper the new powder diffraction data is presented for the UG-2 chromite with an average composition of: (Fe2+0.55Mg0.43Ti0.02)(Cr1.14Fe3+0.23Al0.63)O4.
