Mineralpedia Details for Diaboleite
Diaboleite
Named in reference to the minerals difference from boleite after the Greek prefix dia-, meaning “different,” “separate,” or “apart from.” Diaboleite is a rare mineral that can be found in localities in England, Germany, Italy, Greece, the United States, Iran, Australia, Chile, and Russia, among just a couple others. Diaboleite occurs in oxidized manganese ore, as a secondary mineral in highly oxidized lead-copper ore, and on slag that has been exposed to seawater. Diaboleite is completely soluble in nitric acid.
