It is, however, present largely as Mn3 + emphasizing that the critical factor for the
production of piemontite in the rock is not a high manganese content but an
unusually high oxidation state. Piemontite (Table 6, anal. 8) with tourmaline and ...

Distinctive red to reddish-brown piemontite (Gianella, 1937) and pinkish Mn-
bearing epidote (L.C. Hsu, oral commun., 1990) are locally common in
metaignimbrites about 3 km northwest of Peavine Peak and on Petersen
Mountain to the north.
