Ca2(Mn,Fe)Al2(Si2O7)(SiO4)(O,OH)2
Monoclinic
Piemontite, a calcium manganese aluminum silicate hydroxide mineral of the epidote group, was described from Sterling Hill by Jenkins (1994). It was stated to occur as pink microcrystals associated with johnbaumite and barite. The reported analysis is grossly inadequate for interpretation. Piemontite has not been reported from Franklin.
