Ion-adsorption rare earth elements (iREE) deposits are the globally predominant source of
heavy rare earth elements (HREE), which are mainly discovered and mined in southern …

There has been considerable controversy concerning the role of chemical weathering in the
regulation of the atmospheric partial pressure of carbon dioxide, and thus the strength of the …

The correlation between decreasing reaction rates of silicate minerals and increasing
duration of chemical weathering was investigated for both experimental and field conditions …

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 …

Differential rates of plagioclase and K-feldspar weathering commonly observed in bedrock
and soil environments are examined in terms of chemical kinetic and solubility controls and …

The relationships among climate, physical erosion, and chemical weathering have remained
uncertain, because long-term chemical weathering rates have been difficult to measure …

Quantifying long-term rates of chemical weathering and physical erosion is important for
understanding the long-term evolution of soils, landscapes, and Earth's climate. Here we …

Rock-forming minerals of igneous and metamorphic rocks contain most of the nutrients
required by higher plants for growth and development. Ground rock fertilisers may provide a …

Mineral dissolution kinetics influence such phenomena as development of soil fertility,
amelioration of the effects of acid rain, formation of karst, acid mine drainage, transport and …

Surface area is important in quantifying mineral-water reaction rates. Specific surface area
(SSA) was measured to investigate controls on this parameter for several primary silicate …
