Example of SPL–GXMAP X-ray mapping. The particle has been segmented into grains using the grey-scale image. Each grain is tested with a single X-ray spot. If the composition is indicative of a gangue mineral or galena, then only that single X-ray point is used for mineral identification (an example of this is spectrum A, chlorite). If the test spot has the composition of a base-metal sulfide, then the grain is mapped using a 2 × 2 pixel array (spectrum B, pentlandite) or a 1 × 1 pixel array if the composition is indicative of a PGM (spectra C and D, tsumoite and michenerite). Inset diagram shows final mineralogy of the particle, consisting of a complex intergrowth of two michenerite grains (bright pink) in tsumoite (light grey), all of which are mostly surrounded by chlorite (green). Other minerals include pentlandite (red) and pyrrhotite (light pink orange).
