Weathering is a very general term for the processes by which rocks undergo physical and
chemical alteration at the earth's surface. In this paper we shall be concerned only with …

A model is used to evaluate the relative importance of temperature, soil pCO2, and organic
acidity on silicate weathering rates in an average soil of warm temperate climate. The model …

Soil can be defined as" a natural body consisting of generally unconsolidated layers or
horizons of mineral and/or organic constituents of variable thickness which differ from parent …

This paper describes the ways in which the major rock-forming primary minerals (olivine,
pyroxenes, amphiboles, feldspars, micas and chlorites) break down during weathering, the …

Several important developments in our understanding of the chemistry of weathering have
occurred in the last few years: 1. There has been a major breakthrough in our understanding …

Comparison between mineral weathering rates determined in the laboratory and in the field
commonly reveals large discrepancies, with order (s)-of-magnitude lower rates in the field …

Long-term weathering rates (RLT) were determined from base cation depletion in soil
profiles developed on six granitic glacial moraines varying in age from 0.4 to≥ 297 ka in the …

Silicate minerals, constituting more than 90% of the rocks exposed at the earth's surface, are
commonly formed under temperature and pressure conditions that make them inherently …

The understanding of chemical weathering is of importance for analyzing and understanding
a large number of important environmental issues. Acidification of soils and waters are …

Aluminosilicate minerals undergo surface-controlled dissolution reactions that are fractional
order with respect to bulk H (+) ion concentration in solution. Kinetics of chemical weathering …
