An occurrence of grunerite at Pierrefitte, Hautes-Pyrénées, France

Abstract

As grunerite is a somewhat uncommon mineral, and as its occurrence at Pierrefitte in association with lead and zinc ore is unusual, if not unique, it may be worth while to put on record the following notes on some material which I collected during an examination of the Pierrefitte deposits. The name 'grunerite' was originally given to a fibrous mineral approximating in composition to FeSiO3 and occurring with magnetite and garnet at Collobrières in the dept. of Var, in the south of France, which was described by Gruner in 1847. It was originally supposed to be a pyroxene, but was later shown by Des Cloizeaux and Lacroix to belong to the amphibole group. A similar mineral occurs in the iron deposits of the Lake Superior district, and elsewhere ; but it has not been recorded from the Pyrenees.
