摘要:Abstract(#br)Elevated concentrations of uranium have been found in many bauxite deposits, but the status of uranium in the ores and the mechanisms of enrichment have not been well understood. In this paper, we report a new case of uranium enrichment in a paleo-karstic bauxite deposit...

摘要:Abstract(#br)Cobalt can be enriched in a variety of different geologic settings, while it is mainly produced as a by-product of sediment-hosted stratiform Cu deposits and magmatic Ni-Cu deposits associated with mafic and ultramafic rocks. In this study, we report elevated Co con...

摘要:Abstract(#br)Karstic bauxite deposits are widespread in Central Guizhou Province, SW China, and high-grade ores are frequently sandwiched with overlying coal and underlying iron-rich layers and form a special “coal–bauxite–iron” structure. The Lindai deposit, which is...

摘要:Abstract(#br)The Lower Carboniferous Jiujialu Formation bauxite deposits at Zunyi, northern Guizhou are distinguished by their great thickness (to 110 m) and cyclic alternation of bauxite ore and bauxitic claystone layers. These features are typical of the Kazakhstan subtype of k...
