Name:Named for Thérèse Magnan for her contributions to knowledge about the Cap Garone 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)

Classification of Thérèsemagnanite

IMA status:Approved 1991

Dana 8th edition ID:31.2.5.1
