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

A revised model of global silicate weathering considering the influence of vegetation cover on erosion rate [PDF]
Geoscientific Model DevelopmentSilicate weathering, which is of great importance in regulating the global carbon cycle, has been found to be affected by complicated factors, including climate, tectonics and vegetation. However, the exact transfer function between these factors and the

Physical and chemical weathering rates and CO2 consumption in a tropical lateritic environment: the upper Niger basin [PDF]
, 1998 The chemical composition of Niger river water measured bimonthly at Bamako Mali. during the period 1990–1992 provides an estimate of present weathering rates in the upper Niger basin.

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..

Variation of Soil Aggregation along the Weathering Gradient: Comparison of Grain Size Distribution under Different Disruptive Forces. [PDF]
PLoS ONE, 2016 The formation and stabilization of soil aggregates play a key role in soil functions. To date, few studies have been performed on the variation of soil aggregation with increasing soil weathering degree. Here, soil aggregation and its influencing factors
