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 ...

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.

Episode of intense chemical weathering during the termination of the 635 Ma Marinoan glaciation [PDF]

Proceedings of the National Academy of Sciences, 2016
Significance At least two extreme glaciations (dubbed as snowball Earth events), each lasting millions of years and affecting the entire globe, occurred during the Cryogenian Period (∼720–635 Ma). These glaciations are recorded by globally distributed glacial deposits overlain by cap carbonates.

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 ...

Ge-Si RATIO FOR ASSESSING THE CHEMICAL WEATHERING INTENSITY AT THE PALEOCENE-EOCENE BOUNDARY IN ANCIENT TRANSURALIAN BASIN

Известия Томского политехнического университета: Инжиниринг георесурсов, 2020
Relevance. Diatomites and their transitional differences formed in the Paleocene–Eocene marine basin are one of the most widespread in the near-surface occurrence of sedimentary rocks in the vast territory of the Trans-Urals. At the same time, with regard to the genetic aspects of such rocks, the discussion on the fundamental sources of silica for ...

The significance of river water physico-chemical monitoring: is climate change increasing the intensity and rate of rock weathering?

Discover Water
Abstract The alteration of rainfall patterns, the possible worldwide increase of mean temperatures, and the recurrence of extreme climatic events roughly describe climate change, as widely perceived. Accordingly, geochemical investigations are researching if climate change may accelerate the weathering of crustal rocks, through its net effect on the ...
