Chemical Weathering Intensity as a Reliable Indicator for Southwest Summer Monsoon Reconstruction: Evidence From Clay Minerals of Qionghai Lake Sediments Since the Last Glacial Maximum

Geochemistry, Geophysics, Geosystems, 2023
Studying the evolution history of the southwest summer monsoon (SSM) throughout geological time, particularly during its strongest period in the Holocene, can improve our understanding of its variation and driving mechanisms, and even help predict future

K isotopes trace temporal silicate weathering intensity [PDF]

Nature Communications
Silicate weathering alters the biogeochemical compositions of the lithosphere, hydrosphere, and atmosphere, and thereby regulates both nutrient cycling and habitable temperatures on Earth, but tracing silicate weathering effectively remains a challenge ...

Reconstructing Chemical Weathering Intensity in the Mekong River Basin Since the Last Glacial Maximum [PDF]

Paleoceanography and Paleoclimatology, 2019
AbstractHigh‐resolution clay mineralogy and major element geochemistry of Core SO18383‐3 collected off the Mekong River mouth in the southern South China Sea have been investigated, aiming to reconstruct sediment provenance and chemical weathering intensity since the last glaciation.

Tectonic and climatic forcing of chemical weathering intensity in the northeastern Tibetan Plateau since the middle Miocene

Catena, 2022
Abstract Chemical weathering of continental silicates is a crucial geological process in regulating Earth’s long-term climate and participating in global carbon cycle. The increasing aridity and active tectonic settings in the northeastern Tibetan Plateau since the middle Miocene, combining the global cooling background, make this region ideal for ...

Chemical weathering intensity and terrigenous flux in South China during the last 90,000 years – evidence from magnetic signals in marine sediments

Frontiers in Earth Science, 2016
The level of chemical weathering is strongly affected by climate. We presented magnetic properties associated with element ratios from the northern part of the South China Sea to denote links between chemical weathering intensity and monsoon changes in ...

Quantifying chemical weathering intensity and trace element release from two contrasting basalt profiles, Deccan Traps, India [PDF]

Chemical Geology, 2014
Weathering profiles developed on basalt substrate contain information relevant to climate, atmospheric composition and evolution, nutrient release into the hydrosphere, and understanding Martian regolith. In this study, the chemical compositions of two profiles developed on Deccan Trap basalt are examined. One is sub-Recent and has only progressed to a

The Hydrochemistry Characteristics and Chemical Weathering Intensity of an Anthropogenically Involved Catchment, South China

Water (Switzerland)
The hydrochemical characteristics of watersheds are influenced by many factors, with chemical weathering and human activities exerting the most substantial influence. Performing a quantitative evaluation of the factors contributing to the chemical weathering of rocks is of significant scientific importance. This research zeroes in on the Qingtang River

Intensive Chemical Weathering in the Arctic During the Miocene Climatic Optimum [PDF]

Palaeogeography, Palaeoclimatology, Palaeoecology, 2023
The Arctic today has shallow, chemically immature, and frost-dominated weathering regimes. At Sokli, Finland (68°N), a 70 m deep palaeo-weathering profile is developed in a Devonian carbonatite pipe that represents fundamentally different past weathering environments.

Chemical weathering detection in the periglacial landscapes of Maritime Antarctica: New approach using geophysical sensors, topographic variables and machine learning algorithms

Geoderma, 2023
The chemical weathering intensity in Antarctica is underestimated. As the chemical weathering intensity increases, hydrological, geochemical and geophysical changes occur in the different environmental spheres and at their interfaces through reactions ...
