A global temperature control of silicate weathering intensity [PDF]

Nature Communications, 2022
How silicate weathering responds to and regulates Earth’s climate remain controversial. This study suggests the primary control of temperature on weathering intensity globally and the temperature-weathering feedback may be stronger in cold Earth.

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 ...

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

Rhenium isotopes reveal enhanced rock organic carbon oxidation over the Toarcian Oceanic Anoxic Event [PDF]

Nature Communications
Weathering plays a central role in the geological carbon cycle. Silicate mineral weathering is invoked as a stabilizing feedback on CO2 emissions, for example from volcanism during the emplacement of Large Igneous Provinces.

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 ...

Feedbacks between the formation of secondary minerals and the infiltration of fluids into the regolith of granitic rocks in different climatic zones (Chilean Coastal Cordillera) [PDF]

Earth Surface Dynamics, 2023
Subsurface fluid pathways and the climate-dependent infiltration of fluids into the subsurface jointly control the intensity and depth of mineral weathering reactions.

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 ...

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

Geophysical 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.

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

Revista 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 ...
