Strontium isotopes as tracers of ecosystem processes: theory and methods
TL;DR: The strontium (Sr) isotope method can be a powerful tool in studies of chemical weathering and soil genesis, cation provenance and mobility, and the chronostratigraphic correlation of marine sediments.
Journal ArticleDOI
REE fractionation during granite weathering and removal by waters and suspended loads: Sr and Nd isotopic evidence
TL;DR: In this article, ICP-MS and TIMS measurements were performed on both solid samples (fresh granite, soil, and suspended load of the stream) and waters (soil solutions, springwater, and streamwater) to determine their respective REE concentrations and Sr and Nd isotopic compositions.

Radiogenic isotopes: systematics and applications to earth surface processes and chemical stratigraphy
TL;DR: Radiogenic isotopes have wide application to chemical stratigraphy, geochronology, provenance studies, and studies of temporal changes in Earth surface processes as discussed by the authors, and they can be used for stratigraphic correlation and to assess changes through Earth history in processes such as tectonic uplift, climate change, biogeochemical cycling, ocean circulation, crustal growth, and surface water evolution.

Present denudation rates on the island of Réunion determined by river geochemistry: Basalt weathering and mass budget between chemical and mechanical erosions
Pascale Louvat,Claude J. Allègre +1 more
TL;DR: In this article, the suspended loads of the main streams on the island of Reunion have been analyzed for their major and trace element contents in order to characterise both chemical and mechanical erosion products.

Chemical kinetics of water-rock interactions
TL;DR: In this paper, the authors provide a quantitative framework for the description of weathering and alteration in sedimentary petrology, using the available experimental data on dissolution of silicates to verify quantitatively the usual mineral stability series.

Chemical processes affecting alkalis and alkaline earths during continental weathering
TL;DR: In this article, the alkali and alkaline earth compositional changes in the Toorongo Granodiorite weathering profile are typical of changes occurring during weathering of the continents, consequently the following generalizations apply to continental weathering.
