Continental recycling: The oxygen isotope point of view
TL;DR: In this article, the authors estimate a δ18O value of 8.9 ± 0.7 for the continental crust, which is the product of two competing processes, namely, the erosion and growth of continental masses.

Permeability, porosity, and mineral surface area changes in basalt cores induced by reactive transport of CO2‐rich brine
Andrew J. Luhmann,Benjamin M. Tutolo,Brian C Bagley,David F. R. Mildner,William E. Seyfried,Martin O. Saar +5 more
TL;DR: In this article, four reactive flow-through laboratory experiments were conducted on intact basalt cores to assess changes in porosity, permeability, and surface area caused by CO2-rich fluid-rock interaction.
Journal ArticleDOI
Biogeochemical transformation of greenhouse gas emissions from terrestrial to atmospheric environment and potential feedback to climate forcing
TL;DR: This review highlights the different anthropogenic GHG emission sources, the response of microbial communities to climate change, climate forcing potential, and mitigation strategies through different agricultural management approaches and microbial communities.

Chemical weathering of silicate rocks in Aldan Shield and Baikal Uplift: insights from long-term seasonal measurements of solute fluxes in rivers
TL;DR: In this paper, a reassessment of available information from the Russian Hydrological Survey on long-term seasonal measurements of water, suspended matter and dissolved major element discharges in ∼30 small and large watersheds draining acid silicate rocks (granites, gneisses, quartzites, shales) of the Aldan Shield and Baikal Uplift was combined with new data on river water chemistry for three granitic watersheds in order to calculate the fluxes of elements due to chemical weathering.

Chemical weathering in the river basins of the Himalaya, India
S. Krishnaswami,Sunil K. Singh +1 more
TL;DR: The suggestion that silicate weathering in the Himalaya may be a driver of global cooling during the Cenezoic 1 - 3 has prompted many studies on rivers draining the Himalayan, especially the source waters of the Ganga-Brahmaputra.

Global silicate weathering and CO2 consumption rates deduced from the chemistry of large rivers
TL;DR: In this article, newly compiled data on the 60 largest rivers of the world are used to calculate the contribution of main lithologies, rain and atmosphere to river dissolved loads, and the relationship between the chemical weathering rates of silicates and the possible controlling parameters are explored.

The carbonate-silicate geochemical cycle and its effect on atmospheric carbon dioxide over the past 100 million years
TL;DR: In this article, a computer model has been constructed that considers the effects on the CO/sub 2/ level of the atmosphere, and the Ca, Mg, and HCO/sub 3/ levels of the ocean, of the following processes: weathering on the continents of calcite, dolomite, and calcium-and-magnesium-containing silicates; biogenic precipitation and removal of CaCO 3/from the ocean; removal of Mg from the ocean via volcanic-seawater reaction; and the metamorphic-magmatic decarbon

Tectonic forcing of late Cenozoic climate
TL;DR: In particular, tectonically driven increases in chemical weathering may have resulted in a decrease of atmospheric C02 concentration over the past 40 Myr as discussed by the authors. But this was not shown to be the case for the uplift of the Tibetan plateau and positive feedbacks initiated by this event.

Geocarb III: A Revised Model of Atmospheric CO2 over Phanerozoic Time
TL;DR: In this article, the GEOCARB model has been updated with an emphasis on factors affecting CO2 uptake by continental weathering, including the role of plants in chemical weathering and the application of GCMs to study the long-term carbon cycle.

A negative feedback mechanism for the long‐term stabilization of Earth's surface temperature
TL;DR: In this article, it is suggested that the partial pressure of carbon dioxide in the atmosphere is buffered, over geological time scales, by a negative feedback mechanism, in which the rate of weathering of silicate minerals (followed by deposition of carbonate minerals) depends on surface temperature, which in turn depends on the carbon dioxide partial pressure through the greenhouse effect.
