Paleogene laterites bearing the highest insect ichnodiversity in paleosols
(Geological Society of America, 2016-01)
Research on laterites deals mostly with geomorphological and geochemical characterization of extant tropical systems, with few examples of sedimentologic and paleosol analyses of mid-latitude detrital records. Extra-tropical, ...
Manganese and cobalt redox cycling in laterites; Biogeochemical and bioprocessing implications
(2020)
Cobalt is essential for the modern technology that underpins the decarbonisation of our economies, but its supply is limited leading to its designation as a critical metal. Cobalt biogeochemistry is poorly understood, yet ...
Statistical analysis of lake sediment geochemical data for understanding surface geological factors and processes: An example from Amazonian upland lakes, Brazil
(Elsevier B.V., 2019-04-01)
Statistical evaluation applied to geochemical data of upland lake sediments and their catchment basins rocks from Serra dos Carajas was used to identify geochemical signatures associated with underlying processes, sediment ...
Dating kaolinite from the Neogene Içá Formation and overlying laterites, central Amazonia, Brazil: Constraints for a stratigraphic correlation
(2020-09-15)
The Neogene Içá Formation is a major sedimentary deposit in central Amazonia (Brazil) that is critical to the understanding and modeling of the evolution of the Amazon Basin. However, its chronostratigraphy is poorly ...
Geochemical conceptual model of BTEX biodegradation in an iron-rich aquifer
(2019-01-01)
A geochemical conceptual model was developed to interpret long-term field monitoring data of the chemical speciation related to BTEX biodegradation in a tropical iron-rich aquifer that was contaminated by a large volume ...
