Mineralpedia Details for Luetheite
Named in honor of Ronald D. Luethe who was a Geologist for the Phelps-Dodge Corporation in Arizona and was the first to find the mineral. Luetheite is a rare mineral that occurs only in the United States in Arizona at its type locality in the Patagonia district and in one other unnamed prospect, and in Arizona at the Majuba Hill mine. A third locality lies in Australia at Bali Lo in the Ashburton Downs in Western Australia. Luetheite occurs in intensely altered volcanic rock as cavity fillings and in oxidized copper deposits.
