Nomenclature manganese oxides

Table 2. T(m,n) nomenclature scheme for manganese oxides, according to Turner and Buseck ]4]...

More than 20 manganese oxide phases have been described from continental manganese deposits, but very few of these minerals have been positively identified from marine environments (Table 3). Useful summaries of the nature and nomenclature of the marine manganese minerals include those of Cronan (1976b), R. G. Bums and V. M. Burns (1979), and Post (1999). Marine manganese oxides are hydrous phases usually with poor crystallinity. They are often intimately intergrown with other phases, particularly iron-oxy-hydroxides and hydrous iron oxides. Marine manganese-oxide minerals host a variety of minor elements of economic...
