From: Chromitite layers indicate the existence of large, long-lived, and entirely molten magma chambers
Results of high-resolution X-ray computed tomography revealing that nearly all chromite grains in UG1 chromitite are interconnected within a continuous 3D framework. (a) Three orthogonal slices virtually cut through the UG1 sample (HX-07–153.33, Mototolo mine, Eastern Limb) showing chromite in light grey;(b) Segmented chromitite showing how a single interconnected network (coloured in yellow) covers the entire sample volume; (c) Volume rendering of chromite grains displayed using a false 256 colour scale; (d) Expanded view of a volume of interest showing details of the interconnected chromite network (orange) and the isolated chromite grains (in cyan); (e) and (g) Details of selected chromite cluster morphologies within the large interconnected chromite network where only a small number of grains are coloured to improve visibility. Note that most chromite crystals are touching each other along crystal faces; (f) Histogram showing the size distribution of chromite grains in the sample (ESD: equivalent sphere diameter).
