Nature and development of supergene manganese deposits

Nov 01, 1988· Geologic setting The oxidic manganese ore body on Groote Eylandt (Figs. 1 and 2) is one of the largest de- posits in the world. Similar to Chiatura and Ni- kopol (U.S.S.R.), the Groote Eylandt ores probably formed in a shallow water marine en- vironment and occur mainly as primary Mn- oxide oolites, pisolites and small amounts of hardgrounds, associated with various second- ary ores.
