About Asbestos hedyphane
Colour:
Grey to brownish
Lustre:
Silky
An oriental overgrowth of a kaolinite-serpentine group mineral and a Pb,Ca arsenate of apatite type.
The material may look like asbestiform chrysotile.
Up to 2.5 cm large, grey to brownish aggregates with a silky lustre found at LÃĨngban, Sweden were described by SjÃķgren (1991) as astbesthedyfan (asbestos hedyphane).
Fibres of this material was investigated with transmission electron microscopy by Hansen & O'Keeffe (1988). They showed that it consists of a mixture of a kaolinite-serpentine group mineral (antigorite ?) and a Ca arsenate with some Cl not identical with hedyphane. The latter might be identical with hydroxylhedyphane ("the hydroxyl-bearing analogue of hedyphane described by Dunn et. al (1985)" (Holtstam et al. 1999).
