We found a rodingite block enclosed in serpentinite at Hadeba area in the Besshi district. White diopside-epidote-calcite veins crosscut the greenish matrix composed of grossular-diopside-clinochlore. X-ray elemental map for U revealed that the concentration of U was, in descending order of abundance, titanite, grossular, diopside, epidote, and clinochlore.
