About VillamaníniteHide

05302770015140252603060.jpg
Villamanín de la Tercia
Formula:
(Cu,Ni,Co,Fe)S2
Colour:
Iron-black to greenish black
Lustre:
Metallic
Hardness:
Specific Gravity:
4.4 - 4.5
Crystal System:

Member of:
Name:
Named after the town of Villamanín, Spain, near the type locality of the Providencia mine. In the original description (Schoeller and Powell, 1919), the title of the paper names it villamaninite (without diacritical marks) and in the paper as villàmaninite, which might be a typographical error as accent grave is not used in Spanish. The current spelling of the name is villamanínite, with the diacritical matching the town name.
