About HedyphaneHide

White, yellowish white, buff, bluish; colourless in transmitted light.
Resinous, Greasy
4 - 5
Specific Gravity:
Crystal System:
First described from Långban, Sweden and named in 1830 by Johann Friedrich August Breithaupt from the Greek ηδύς for "sweet" or "beautiful" and φαίνεσθαι, "to appear", in allusion to the typical appearance and luster of specimens. Redefined by Roland C. Rouse, Pete J. Dunn, and Donald R. Peacor (1984).
Isostructural with:
A relatively rare mineral of the Apatite Supergroup found in metamorphosed manganese deposits. The Pb3Ca2 analogue of Turneaureite and Mimetite. The arsenate analogue of Phosphohedyphane. Also the chlorine analogue of hydroxylhedyphane.

Pb and Ca atoms are ordered on two different cation sites (M1 and M2) in the crystal structure.
Formerly thought to be a Ca-bearing variety of mimetite. A hydroxyl analogue "hydroxylhedyphane" may exist.
