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.

Surface hydration‐induced damage in tight oil‐bearing sandy conglomerate reservoirs
Deep Underground Science and Engineering, EarlyView.A series of techniques such as X‐ray diffraction, scanning electron microscopy, energy‐dispersive spectroscopy, conductivity tests, and infrared thermal imaging were used. The key findings are the identification of a two‐stage surface hydration process and the elucidation of the effects of various minerals and elements on the hydration process ...

The circular nutrient economy of terrestrial ecosystems and the consequences for rock weathering
Frontiers in Environmental Science, 2023 Earth’s biosphere is thought to exert a substantial influence on regolith evolution and chemical weathering rates. However, ecosystems are also highly efficient at retaining and recycling nutrients.

A numerical examination of the effect of sulfide dissolution on silicate weathering
Earth and Planetary Science Letters, 2020 Silicate weathering regulates climate on geological time scales as a net, climate-sensitive sink of atmospheric CO2. On the other hand, sulfuric acid produced through sulfide dissolution affects silicate weathering, diminishing its effectiveness as a ...

Lithium isotopes trace silicate weathering-driven authigenic carbonate formation in marine sediments
Communications Earth & EnvironmentMarine authigenic carbonates are considered a major long-term carbon sink, yet the role of silicate weathering in their formation remains unclear. Here we use lithium isotope compositions of authigenic carbonates from the Gulf of Mexico to trace the ...

Atmospheric CO2 consumption by continental erosion : present-day controls and implications for the last glacial maximum [PDF]
, 1998 The export of carbon from land to sea by rivers represents a major link in the global carbon cycle. For all principal carbon forms, the main factors that control the present-day fluxes at the global scale have been determined in order to establish global
