About Richelsdorfite
Formula:
Ca2Cu5Sb(AsO4)4(OH)6Cl · 6H2O
Colour:
Turquoise-blue
Lustre:
Vitreous
Hardness:
2
Crystal System:
Monoclinic
Name:
Named after its discovery locality, Wilhelm Mine (Wechselschacht), Bauhaus, Richelsdorf District, North Hesse, Hesse, Germany.
Several richelsdorfite-like, Sb- and/or Cl-free "varieties" also exist (e.g., Walenta, 2000). Some of them probably are new species or possibly polytypes.
A "carbonate-richelsdorfite" has been characterised by Drescher and Susse (1997) and was tentatively identified by Gröbner (2000).
Structurally related to the Lavendulan Group.
