Chlorine isotope fractionation recorded in atacamite during supergene copper oxidation
(Elsevier B.V., 2019)
© 2019In the Atacama Desert of northern Chile, large amounts of the copper hydroxy-chloride mineral atacamite (Cu2Cl(OH)3) are formed in the supergene oxidation zone of Cu deposits. Since atacamite requires saline water ...
Mapeamento de Paleosuperfícies associadas a identificação de depósitos supérgenos de cobre como ferramenta de exploração mineral na região de Itapeva e Ribeirão Branco- Vale do Ribeira, estado de São Paulo, Brasil
(2010-12-01)
A few examples of supergene ore formation and their interaction with morphogenesis (palaeosurfaces) and weathering mineralogy are discussed. Geomorphological and mineralogical records to characterize palaeosurfaces associate ...

Supergene enrichment of copper deposits since the onset of modern hyperaridity in the Atacama Desert, Chile
(SPRINGER, 2009-07)
Supergene enrichment of Cu deposits in the
Atacama Desert has played a critical role in making this
the prime Cu-producing province of the world. Previously,
this has been believed to have occurred exclusively over ...
Iodine-rich waters involved in supergene enrichment of the Mantos de la Luna argentiferous copper deposit, Atacama Desert, Chile
(SPRINGER, 2009-08)
Recent studies have suggested the involvement of highly saline deep formation waters that modified preexisting Cu assemblages to form atacamite during supergene oxidation of Cu deposits in the Atacama region. In this report, ...
