『Abstract
　Electron microprobe analyses of caryopilite show that the octahedral cation to silicon ratio is close to 8:6, \consistent with a friedelite structure type, rather than the 9:6 ratio expected for a serpentine type. The powder X-ray diffraction patterns are very similar to those of friedelite but somewhat different from those of serpentine. We propose that caryopilite is friedelite-like rather than a member of the serpentine group as is generally assumed.』
