Gold-bearing iron duricrust in Central Brazil
(1991-11-01)
In the Cuiabá region-State of Mato Grosso, Central Brazil-primary gold mineralization is hosted by two generations of quartz veins in Precambrian metamorphic terrains of the Cuiabá Group. Gold is mined from the veins and ...

Weathering of metapelites from the Quadrilátero Ferrífero mineral province, southeastern Brazil
(Bulletin of Engineering Geology and the Environment, 2019)
Weathering profiles in granites, Sierra Norte (Córdoba, Argentina)
(Pergamon-Elsevier Science Ltd, 2005-09)
Abstract: Two weathering profiles evolved on peneplain-related granites in Sierra Norte, Córdoba province, were examined. Several weathering levels, of no more than 2 m thickness, were studied in these profiles. They had ...
Regolith production and chemical weathering of granitic rocks in central Chile
(Elsevier, 2016)
We have evaluated the long-term chemical and physical weathering mass balance of an anomalously thick saprolite profile (>30 in thickness) developed in granitic rocks near Curacavi, Coastal Range of central Chile. The ...
Weathering processes and dating of soil profiles from São Paulo State, Brazil, by U-isotopes disequilibria
(2017-01-01)
This study reports the use of the U-series radionuclides 238U and 234U for dating two soil profiles. The soil horizons developed over sandstones from Tatuí and Pirambóia formations at the Paraná sedimentary basin, São Paulo ...
