Silicate rock weathering and atmospheric/soil CO2 uptake in the Amazon basin estimated from river water geochemistry: seasonal and spatial variations [PDF]
, 2003 Using the data of the CAMREX project (1982–1984) on the water geochemistry of the Amazon river and its main tributaries, it was possible to assess the silicate rock weathering processes and the associated consumption of atmospheric/soil CO2, taking into

Chemical weathering in hardened volcanic horizons (tepetates) of the State of Mexico
Revista Mexicana de Ciencias Geológicas, 2022 Weathering is one of the most important phenomena that affect the balance dynamics of the Earth's crust. The chemical composition of soil samples and hardened horizons from seven profiles (P1 to P7) of the State of Mexico was compared to detect the ...

Enhanced chemical weathering of rocks during the last glacial maximum: a sink for atmospheric CO2? [PDF]
, 1999 It has been proposed that increased rates of chemical weathering and the related drawdown of atmospheric CO2 on the continents may have at least partly contributed to the low CO2 concentrations during the last glacial maximum LGM..

Evaluating the Effects of Sedimentary Cycles (Aeolian and Fluvial) on Chemical Weathering Indices in Rafsanjan Region, Southeast of Iran [PDF]
Desert, 2022 Chemical indices are widely used for characterizing the degree of weathering. In this study, we focused on evaluating the capability of chemical weathering indices to distinguish the sequence of aeolian-fluvial sediments in an arid region of Iran.

Luminescence Sensitivity of Quartz From Rocks Under in situ Chemical Weathering Conditions
Frontiers in Earth Science, 2022 In provenance investigation of Quaternary sediments, quartz luminescence sensitivity (QLS) has been employed as a technique. The weathering and influence on the earliest signs of luminescence sensitivity of sedimentary quartz require more consideration ...

Predicting Water Cycle Characteristics from Percolation Theory and Observational Data. [PDF]
, 2020 The fate of water and water-soluble toxic wastes in the subsurface is of high importance for many scientific and practical applications. Although solute transport is proportional to water flow rates, theoretical and experimental studies show that heavy ...
