Mineralpedia Details for Paraotwayite
Paraotwayite
Named after the Greek word para, meaning “near”, and for the similarity of the mineral to otwayite. Paraotwayite is extremely rare and can be found only at its type locality in the Otway prospect in Western Australia, Australia, and in a newer locality in Chile. Paraotwayite occurs at its type locality as a secondary mineral in veinlets through altered hydrothermal nickel ore deposits within serpentinized peridotite.
