Description

Lengenbachite from Lengenbach, the type and only confirmed locality worldwide (jointly with the nearby Reckibach, also in the Binn valley). It occurs as grey metallic acicular crystals in a contrasting dolomite matrix associated to nice pyrite crystals. One of the most typical Lengenbach species, of course. From a 1991 find. Ex-Willi Musch collection. Very nice under the microscope !
