Eolian deposits of loess on the Chinese Loess Plateau are investigated to decipher the influence of sequentially changed monsoon climate on silicate weathering process. Detailed hydrochloric acid dissolution experiments are applied to establish a sensitive proxy for silicate weathering. Combined elemental and...

The weathering process can be viewed as a transformation of primary minerals (feldspar) to secondary products (clay minerals) by neutralizing carbonic acid derived from the atmosphere18. Feldspar dissolution is the most common silicate weathering reaction given its high abundance in the upper continental...
For these systems to fairly represent silicate weathering, the changes in isotopic ratios in terrestrial surface waters should correspond to changes in the overall silicate dissolution. This assumes that the silicate mineral phases that act as sources of a given isotope dissolve at a rate that is ...
T he evolution of the Earth has been a complex, long-term process1. The overall trend in the composition of its surface minerals has involved a constant decrease in silicate and an increase in carbonate minerals. Physical2,3 and chemical4 weathering processes are the main forces driving ...
3.Abundant uranyl minerals (especially, uranylsilicatesand uranyl phosphates) are found because of intensive weathering of uraninite. 而我国高放废物地质处置库拟建在花岗岩体中。 4.Our main products: Sucralose, Metallic Stearates, Magnesium trisilicate, Magnesiumsilicate, Calcium acetylacetonate, Synthetic ...
. The thickness of the weathering zone depends on the balance between the downward propagation of the weathering front at depth and physical erosion processes at the surface. When chemical weathering at depth is the dominant process over erosion, the weathering budget can be limited by the accumula...
Hotspots of CO2release during rock weathering appear to lie at the edges of major active mountain ranges where relatively young, marine sedimentary deposits are uplifted and supplied to the oxidation process through denudation. Examples include the shales of the Himalayan collision zones and east of ...
