The Influences of Climatic and Lithological Factors on Weathering of Sediments in Humid Badland Areas

open access: yesFrontiers in Earth Science, 2022
Climate variables including temperature, rainfall intensity, rainfall acidity, and lithological properties are among the most important factors affecting rock weathering.

Chemical weathering in hardened volcanic horizons (tepetates) of the State of Mexico

open access: yesRevista Mexicana de Ciencias Geológicas, 2022
Weathering is one of the most important phenomena that affect the balance dynamics of the Earth's crust. The chemical composition of soil samples and hardened horizons from seven profiles (P1 to P7) of the State of Mexico was compared to detect the ...

The Effect of Size Distribution on the Geochemistry and Mineralogy of Tropical River Sediments and Its Implications regarding Chemical Weathering and Fractionation of Alkali Elements

open access: yesLithosphere, 2022
The mineralogical and geochemical compositions of the sediments deposited by rivers have been used extensively to evaluate past chemical weathering and the physical erosion history of drainage basins at different time scales.

Climate, vegetation, and weathering across space and time in Lake Tanganyika (tropical eastern Africa)

open access: yesQuaternary Science Advances, 2021
Climate and vegetation influence weathering rates and processes; however, evaluating the effects of each and feedbacks between systems, has yet to be accomplished for many types of landscapes.

Soil weathering dynamics and erosion in a dry oceanic area of the southern hemisphere (Otago, New Zealand)

open access: yesScientific Reports, 2022
Landscape evolution is driven by tectonics, climate and surface denudation. In New Zealand, tectonics and steep climatic gradients cause a dynamic landscape with intense chemical weathering, rapid soil formation, and high soil losses. In this study, soil,

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

open access: yesProceedings 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. According to the snowball Earth hypothesis, cap

Strong Coupling Between Carbon Cycle, Climate, and Weathering During the Paleocene‐Eocene Thermal Maximum

open access: yesGeophysical Research Letters, 2023
The Paleocene‐Eocene Thermal Maximum (PETM; ∼56 Ma)–a geologically rapid carbon‐release event similar to anthropogenic carbon emissions–is ideal for investigating weathering responses to rapid carbon release and associated climate change.

Sediment source-to-sink processes of the southeastern Indian Ocean during the Late Eocene-Oligocene and their potential significance for paleoclimate

open access: yes地质科技通报, 2022
Understanding the paleoclimate responses in Southern Ocean and its surrounding land can help us to better explore the major climate transition mechanisms in geological history and predict the response ofthe earth system to abrupt climate changes in the ...
