Member of:
Name:
Named in 1889 by Axel Hamberg (1889) from the Greek, χάρυον = nut, due to its brownish color and habit + πίλος = felt, due to its appearance like a feltlike mass in thin sections.
Isostructural with:
Note: A "caryopilite-like mineral", with an X-ray powder diffraction pattern "closer to that of lizardite than to that of caryopilite", was described by Nambu et al. (1981).
