The biogeochemical origin of the Groote Eylandt manganese
The cause of manganese precipitation at Groote Eylandt has been studied chiefly by Frakes and Bolton (1984), who described a mixing model whereby manganese, concen- trated in anoxic water, became mixed with ox- ygenated coastal waters.Abstract. Supergene manganese ores occur on Groote Eylandt in association with other secondary rocks. Overprinting primary sedimentation features (e.g. oolitic and pisolitic units), secondary Mn-oxides and gangue minerals nowadays belong to the most important components in the deposits.Nature and development of supergene manganese deposits, Groote Eylandt

REVIEW of RECENT MANGANESE EXPLORATION in the
manganese deposits mined on Groote Eylandt and recommendations for future work. The main findings of this review are: • Rosie Creek South (and the SW Reconnaissance area) prospect, the siteThe various theories relating to the origin of the Groote Eylandt manganese ores are discussed and a petrogenetic sequence involving biogeochemical precipitation of manganese oxide gels, sedimentary formation of pisolites and concretionary strata, diagenesis, and lateritization is outlined.Evidence for a biogeochemical origin of the Groote Eylandt manganese
