“Vivid concentric spherules (PHOTO SCANNED FROM AN OLD COLOR SLIDE), 0.9 mm in diameter, previously classified as volborthite and referable to the mineral historically known as "vesbine". According to Balassone et al. (2019), the rounded to botryoidal-like concretions, that show a texture with a distinct colloform growth banding, are composed of mottramite and chrysocolla plus vanadinite.
