Increased chemical weathering during the deglacial to mid-Holocene summer monsoon intensification. [PDF]
Sci Rep, 2017 Chemical weathering and the ensuing atmospheric carbon dioxide consumption has long been considered to work on geological time periods until recently when some modelling and natural records have shown that the weathering-related CO2 consumption can ...

Continental igneous rock composition: A major control of past global chemical weathering. [PDF]
Sci Adv, 2017 Changes in the isotopic composition of the continental crust control the strontium isotope ratio in seawater. The composition of igneous rocks in the continental crust has changed throughout Earth’s history.

Sensitivity of chemical weathering and dissolved carbon dynamics to hydrological conditions in a typical karst river. [PDF]
Sci Rep, 2017 To better understand the mechanisms that hydrological conditions control chemical weathering and carbon dynamics in the large rivers, we investigated hydrochemistry and carbon isotopic compositions of dissolved inorganic carbon (DIC) based on high ...

Erosion and weathering in carbonate regions reveal climatic and tectonic drivers of carbonate landscape evolution [PDF]
Earth Surface Dynamics, 2023 Carbonate rocks are highly reactive and can have higher ratios of chemical weathering to total denudation relative to most other rock types. Their chemical reactivity affects the first-order morphology of carbonate-dominated landscapes and their climate ...

Global CO2 Consumption by Silicate Rock Chemical Weathering: Its Past and Future
Earth's Future, 2021 Silicate rock weathering maintains a stable and long‐term absorption of CO2. However, the magnitude, spatial pattern, and evolution characteristics of global silicate rock weathering carbon sink (SCS) remain unclear.

Global chemical weathering dominated by continental arcs since the mid-Palaeozoic
Nature Geoscience, 2021 Earth’s plate-tectonic activity regulates the carbon cycle and, hence, climate, via volcanic outgassing and silicate-rock weathering. Mountain building, arc–continent collisions and clustering of continents in the tropics have all been invoked as ...
