Playfairite (original) (raw)
La playfairita és un mineral de la classe dels sulfurs. Rep el seu nom en honor de John Playfair (1748-1819) científic, matemàtic, físic i geòleg escocès, professor de matemàtiques i a la Universitat d'Edimburg (1785-1819). Conegut pel seu treball pioner sobre la geomorfologia i per la seva explicació de la Teoria de la Terra de James Hutton.

(eu) Playfairite is a rare sulfosalt mineral with chemical formula Pb16Sb18S43 in the monoclinic crystal system, named after the Scottish scientist and mathematician John Playfair. It was discovered in 1966 by the Canadian mineralogist John Leslie Jambor. Lead gray to black in color, its luster is metallic. Playfairite shows strong reflection pleochroism from white to brownish gray. Playfairite has a hardness of 3.5 to 4 on Mohs scale and a specific gravity of approximately 5.72. The type locality is Taylor Pit (Concession XIV; Lot 13), Huntingdon Township, Hastings County in Ontario, Canada. Small deposits have also been found in Les Cougnasses Mine, Orpierre in the Haut-Alpes in France, Khaidarkan Sb-Hg deposit (Chaidarkan), Fergana Valley, Alai Range, Osh Oblast, Kyrgyzstan and Reese River District, Lander County, Nevada, USA.
