The biogeochemical origin of the Groote Eylandt manganese,

The sedimentary manganese ore deposit of Groote Eylandt, Australia, is an example of the Orthoquartzite-Glauconite-Clay Association, and was formed during a short Cenomanian Age transgression and regression across the Middle Proterozoic sandstone basement of the island."Groote Eylandt Manganese Deposits" in Australia,,Manganese deposits are documented at "Groote Eylandt Manganese Deposits." Manganese is present at a grade sufficient to have a strong effect on the economics of an excavation project. It may even be viable as the only commodity mined.History of Manganese Development - Groote Eylandt (BMR,,stationed in Darwin, who claimed to have noticed some of the Groote Eylandt manganese samples in the office of the Darwin Uranium Group and expressed an interest in the occurrences.
