FLUVIAL GEOCHEMISTRY APPLIED TO THE EVALUATION OF CHEMICAL WEATHERING RATES AND SOIL REMOVAL IN RIO CLARO FORMATION
(Uniao Geomorfologia Brasileira, 2016-07-01)
This study aimed to determine through fluvial geochemistry chemical weathering rates and soil removal of Rio Claro formation in Cachoeirinha stream basin, Rio Claro (SP). In the river mouth the discharge, total dissolved ...
Colluvial deposits as a possible weathering reservoir in uplifting mountains
(European Geosciences Union, 2018)
The role of mountain uplift in the evolution of the global climate over geological times is controversial. At the heart of this debate is the capacity of rapid denudation to drive silicate weathering, which consumes CO2. ...
Understanding volcanic weathering processes through geochemical modeling, trace elements and hydrology
(2019)
Chemical weathering produces soils and the necessary nutrients for ecosystems; addi- tionally, it regulates the climate at geologic timescales. Therefore, weathering is a funda- mental process for the Earth’s living layer: ...
Chemical weathering and atmospheric/soil CO2 uptake in the Andean and Foreland Amazon basins
(Elsevier B.V., 2011-08)
This study is a geochemical investigation of the Andean and Foreland basins of the Amazon River at high spatial and time resolution, carried out within the framework of the HYBAM research program (Hydro-geodynamics of the ...
Modeling rock-water interaction of fractured aquifer in itabuna/BA regionModelagem da Interação Água/Rocha nos Aquíferos Fraturados da Região de Itabuna/BA
(2019-01-01)
This research aimed to investigate the geochemical mechanisms that govern the strong hydrochemical variations in the fractured aquifers of the Itabuna/BA region. Plagioclase and quartz comprise the major mineralogy of ...
INFLUENCE OF DISCHARGE ON SILICATE WEATHERING DYNAMICS OF THE TIETÊ RIVER BASIN: MAJOR CATIONS AND DISSOLVED SILICA APPROACH

Dust transport enhanced land surface weatherability in a cooling world
(European Association of Geochemistry, 2023)
The weatherability of exposed silicate rocks drives the efficiency of climatic feedback on the geological carbon cycle through silicate weathering. However, the controls and evolution of land surface weatherability are not ...

Platinum-Group Minerals in Chromitites of the Niquelandia Layered Intrusion (Central Goias, Brazil): Their Magmatic Origin and Low-Temperature Reworking during Serpentinization and Lateritic Weathering
(Mdpi Ag, 2012-12-01)
A variety of platinum-group-minerals (PGM) have been found to occur associated with the chromitite and dunite layers in the Niquelandia igneous complex. Two genetically distinct populations of PGM have been identified ...
