Manganese Dendrites

A variety of Manganese Oxides

Black dendritic films of various visually indistinguishable black manganese oxides, may consist of Birnessite, Coronadite, Cryptomelane, Hollandite, Romanèchite, Todorokite or other species. Many manganese minerals have similar strong x-ray lines and line-broadening can make x-ray diffraction identification ineffectual. Potter and Rossman (1979) have found that infra-red spectroscopy has been helpful in verifying some dendrite mineralogy. Currently, there are no known manganese dendrites in the world which contain Pyrolusite.
