The method described assists in the quantification of oxidic manganese minerals and associated materials from the Groote Eylandt manganese deposits (Northern Territory, Australia) which have been influenced by supergene processes. These ores are commonly composed of very fine grained minerals, intergrown with lateritie components like ...

This will help us understand the geochemical fate of heavy metals in various environments. Ferromanganese duricrust, commonly found in weathering profiles over manganese-rich sedimentary rocks and occasionally observed in soils, consist of manganese oxides and iron oxides, and are generally enriched in heavy metals …

Groote Eylandt (veraltete niederländische Schreibung für Große Insel) ist die viertgrößte Insel Australiens und die größte Insel im Golf von Carpentaria an der Nordküste Australiens.. Auf Groote Eylandt wird eines der größten Manganerzvorkommen der Erde abgebaut.. Die Insel vor der Nordküste Australiens wird von den Aborigines der …

Some 20 different supergene Mn oxide ores and associated secondary rocks from the Groote Eylandt manganese deposit were analyzed for their major, minor, and trace element content. This is the first detailed account of the trace element geochemistry from this deposit and the data presented here should aid in future comparative studies.

The absence of introduced herbivores and cane toads (Rhinella marina) on Groote Eylandt, Northern Territory, provides an opportunity to evaluate some hypothesised threats in isolation of others. We used camera traps to investigate the correlates of native mammal distribution and abundance at 112 lowland savanna sites across Groote …

GEMCO is an open-cut strip-mining operation, producing high-grade manganese ore and is located in close proximity to Asian export markets. It is one of the largest manganese ore producers in the world. We own a …

The mine is operated by the Groote Eylandt Mining Company Pty Ltd (GEMCO), which is majority owned by South 32 Ltd. The ore is mined by shallow open-cut mining methods and is transported by road to a nearby port. Production in 2021-22 totalled 6.06 Mt of manganese ore. The deposit comprises oolitic and pisolitic sedimentary …

These "Groote Eylandt Beds" are of middle Proterozoic age, equivalent to other sandstones in eastern Arnhem Land (Plumb et al., 1980). Cretaceous or post Cretaceous fault block movements have occurred in the region (Frakes, 1979). The basement rocks are overlain conforma- bly by shallow-marine, glauconite-bearing sands …

Groote Eylandt è la più grande isola del golfo di Carpentaria, nell'Australia nord-orientale. Si trova a circa 50 km dal Territorio del Nord e dalla costa orientale della Terra di Arnhem, dista in linea d'aria circa 630 km da Darwin.. Deve il suo nome all'esploratore olandese Jan Carstensz che nel 1623 la chiamò "isola grande" secondo la …

The use of scalp hair to monitor manganese was studied as part of an investigation of manganese intoxication amongst a group of Aborigines living on manganese-rich soil on Groote Eylandt, in the Northern Territory of Australia. High scalp-hair manganese values were due largely to manganese from exog …

Supergene manganese ores occur on Groote Eylandt in association with other secondary rocks. Over 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. The different primary and supergene rock types are …
