English: Images of the rock fragment from Mt Carmel. (a) Back-scattered electron (BSE) image of the hibonite–grossite–spinel aggregate studied. The red box indicates the region enlarged in (b) and (c), which reports X-ray compositional maps, and the green box shows the region enlarged in (d) a BSE image; arrows mark the (V,Al)-alloys and the VH2 fragment (kishonite) that was sampled. (e) Transmitted-light photo (plane polars) of the same rock sample, showing inclusions of metallic vanadium in platy hibonite crystals. (f) BSE image of a typical hibonite crystal showing the zonal distribution of vanadium and (V,Al)-alloys on crystal faces. Crystal orientation is shown by the blue hexagonal prism.
