(Ca-B-silicate)
Mineral-B occurs associated with manganaxinite and minor rhodonite from Franklin (HU# 114040). It forms pink, dull radial sprays of hard crystals. The X-ray powder diffraction data indicate a very close relationship to oyelite, but there are subtle differences between the data for this material and the published data for oyelite. Microprobe analyses of type oyelite and Franklin material indicate they have nearly identical compositions and that fluorine is absent in both. This mineral has been referred to as an oyelite-like mineral in species lists.
