Rare earth elements in a stalagmite from southwestern Japan: A potential proxy for chemical weathering
stalagmite rare earth elements partitioning paleoenvironment chemical weathering
2017/4/10
This study examines the distribution of rare earth elements (REEs) in an 18–4.5 ka stalagmite in southwestern Japan,
with the aim of assessing the utility of such data in paleoenvironmental reconstru...
Dissolved ion analyses of stream water from bamboo forests: Implication for enhancement of chemical weathering by bamboo
weathering rate plagioclase dissolved ions bamboo stream water
2017/4/11
Dissolved ion analyses of stream water were conducted monthly in three catchments of varying bamboo coverage of
similar geological setting for one year. We found that the concentration of dissolved S...
A normalised seawater strontium isotope curve and the Neoproterozoic-Cambrian chemical weathering event
normalised seawater strontium isotope curve chemical weathering event
2009/10/22
The strontium isotope composition of seawater has varied over geological time in response to changes in the rates of continental weathering relative to ocean crust alteration. However, the potential o...
New Chemical Weathering Indices for Estimating the Mechanical Properties of Rocks: A Case Study from the Kürtün Granodiorite, NE Turkey

2009/7/7
The chemical weathering of rock proceeds by water-rock interaction. During weathering geochemically mobile elements, alkali and alkali-earth elements are easily leached from rocks, leaving the residua...
Hematite and Goethite from Duricrusts Developed by Lateritic Chemical Weathering of Precambrian Banded Iron Formations, Minas Gerais, Brazil
Hematite Goethite Laterite Mossbauer Spectrometry
2011/12/1
Abstract: The upper 15–20 m of a 200 m thick lateritic weathering profile on Precambrian itabirites of Capanema, Brazil, reveals a genetic pathway for the formation of hematitic and goethitic nodules ...
Chemical Weathering of Crystalline Rocks in the Catchment Area of Acidic Ticino Lakes, Switzerland
Acid precipitation Aluminum hydroxide Gneiss Iron hydroxide Weathering

Atmospheric acidic deposition introduces hydrogen ions to terrestrial and aquatic ecosystems, which become partially neutralized by chemical weathering. In the southern Alps of Switzerland, small catc...
If a series of rock samples with granitic composition in various stages of chemical weathering is ground in a mortar with distilled water and the pH of the slurry produced is determined, it will be ev...
