Intense Chemical Weathering at Glacial Meltwater-Dominated Hailuogou Basin in the Southeastern Tibetan Plateau [PDF]

Water, 2019
Climate warming has caused rapid shrinkage of glaciers in the Tibetan Plateau (TP), but the impact of glacier retreat on the chemical denudation rate remains largely unknown at the temperate glacial basins. The chemical weathering processes were examined at a temperate glacial basin (HLG) in the southeastern TP based on comprehensive data from the ...

Weathering microenvironments on feldspar surfaces: implications for understanding fluid-mineral reactions in soils [PDF]

, 2008
The mechanisms by which coatings develop on weathered grain surfaces, and their potential impact on rates of fluid-mineral interaction, have been investigated by examining feldspars from a 1.1 ky old soil in the Glen Feshie chronosequence, Scottish ...

Clay Mineralogy of Red Clay Deposits from the Central Carpathian Basin (Hungary): Implications for Plio/Pleistocene Chemical Weathering and Paleoclimate [PDF]

, 2013
Geochemical and mineralogical studies of palaeosols provide essential information for palaeoclimatic and palaeoenvironmental interpretation of continental deposits and can present a proxy for palaeoclimate.

Chemical weathering proxies: An assessment of their robustness to reconstruct Paleozoic climate conditions

Evolving Earth
Several chemical weathering proxies for siliciclastic sedimentary deposits have been proposed over the last fifty years. However, only a few studies have evaluated their robustness for paleoclimate interpretation.
