The manganese oxide minerals, a preliminary report
This paper summarizes the results obtained thus far in an intensive study of the manganese oxide minerals. X-ray powder photographs, supplemented by chemical tests, have proved to be the best means for identifying these minerals. Formulas are suggested. Physical properties and X-ray data are listed for the commoner minerals and those for which new data have been obtained. Rules of nomenclature for these minerals are suggested.
