Special Info: Type Locality

A most interesting specimen having a large crystalline mass of light purple or lilac Hedyphane which seems to phase into what is called 'asbeshedyfan' or asbestos hedyphane as Bollmark et al describes in the Langban book on page 125. The description in the book seems to correlate well with this and the other specimen like it in this Special Edition. Ex. Krantz with tag. The tag mentions Mimetite, which is doubtful.

Not much to this mineral. It's a hrydrated iron silicate with a jet black, vitreous luster. This specimen looks close to an obsidian, dark glassy, crystalline mass.
