Devitoite

Devitoite

Named to honor Alfred Devito who was a prominent mineral collector of micromounts in particular and a field collector and contributor to the mineralogical community of California in the United States. Devitoite is a rare mineral that can be found only at its type locality in the Esquire No. 8 claim in the Big Creek-Rush Creek district of California, USA. There, it occurs as “an alteration product of gillespite along fractures and parting planes in a sanbornite-bearing rock.”
