Behavioral differences between weathering and pedogenesis in a subtropical humid granitic terrain: Implications for chemical weathering intensity evaluation

CATENA, 2021
Abstract Continental weathering plays a crucial role in the evolution of the Earth’s surface by linking Earth's spheres, shaping landscapes and regulating chemical cycles and global climate. Regolith weathering studies in some cases ideally assume successive and progressive bottom-up physicochemical variation trends.

The constancy of chemical weathering intensity on hillslopes in the arid to semiarid Qilian Mountains, NE Tibetan Plateau

Science of The Total Environment, 2023
Quantifying the relationship between the chemical weathering and denudation rates of active orogenic belts over a range of climates is the key to addressing the controversy over the uplift-weathering hypothesis. However, studies have focused on warm and humid environments and have not examined cold and arid environments.

Chemical weathering intensity of the Late Cenozoic “Red Clay” deposits in the Carpathian Basin

Geochemistry International, 2007
INTRODUCTIONVery little work had been previously done on thistopic in Hungary. In the past decade, little attention hasbeen paid to the red clay in the Carpathian Basin. Dif-ferent views on the formation, properties, and distribu-tion of red clays have been published by severalauthors. Many geologists draw parallels between redclays and bauxites [1–3].

Geochemical studies on the intensity of chemical weathering in Luochuan loess-paleosol sequence, China

Science in China Series D: Earth Sciences, 1998
Major and trace element analyses of the Luochuan loess-paleosol sequence in China were performed in order to understand the cheniical weathering processes occurring on the I.oess Plateau during the last 600 ka. Results reveal that most elements in the loess remain immobile durlng chemical weathering.

Impact of low denudation rates on soil chemical weathering intensity: A multiproxy approach

Chemical Geology, 2017
Abstract Quantifying the influence of denudation, i.e., physical erosion and chemical weathering, on soil weathering intensity is an important component for a comprehensive understanding of element biogeochemical cycles. The relation between the weathering intensity and the denudation rate is not clear and requires further investigation in a variety ...

Formation of plinthite mediated by redox fluctuations and chemical weathering intensity in a Quaternary red soil, southern China

Geoderma, 2021
Abstract Widely distributed Quaternary red soils (QRSs) in southern China represent the product of intense chemical weathering under a warm and humid climate. Soil containing plinthite is an important part of China’s QRSs, yet the soil environment and mechanism of formation of QRS with plinthite have been insufficiently studied. By comparing iron and

Chemical weathering intensity and element migration features of the Xiashu loess profile in Zhenjiang, Jiangsu Province

Journal of Geographical Sciences, 2008
The chemical weathering intensity and element migration features of the Xiashu loess profile in Zhenjiang are studied in this paper. (1) The Xiashu loess profile underwent moderate chemical weathering. It seems that the precipitation is a more important factor than the temperature in controlling the process of the chemical weathering.
