About Thérèsemagnanite
Formula:
NaCo4(SO4)(OH)6Cl · 6H2O
First described as a (Na-free) mineral with the formula (Co,Zn,Ni)6(SO4)(OH,Cl)10·8H2O, redefined in 2015. The formula was then redefined by Kasatkin et al. (2018) and the structure established by Mills et al. (2019).
Colour:
Pink to light pink
Lustre:
Pearly
Hardness:
1½ - 2
Specific Gravity:
2.52
Crystal System:
Trigonal
Member of:
Name:
Named for Marie-Thérèse Magnan (Toulon, France) for her contributions to knowledge about the Cap Garonne mine, Var (France).
Thérèsemagnanite may be closely related to gordaite (Kolitsch, unpubl. data, 1999):
- the indexed X-ray powder patterns of both minerals are very similar
- both gordaite and thérèsemagnanite are uniaxial negative and their refractive indices and birefringence are quite similar
- thérèsemagnanite may contain Na (possibly overlooked because of Na/Zn peak overlap)
Redefined by IMA in 2015 as a mineral of the gordaite group (IMA 15-K).
Chemically similar to cobaltoblödite.
