Basalt weathering laws and the impact of basalt weathering on the global carbon cycle
TLDR
In this paper, the chemical weathering of basalts and the flux of carbon transferred from the atmosphere to the ocean during this major process at the surface of the Earth were investigated.About:

Silicate Rock Weathering and the Global Carbon Cycle
Gislason,Eric H. Oelkers +1 more
TL;DR: Silicate weathering and soil formation is critical to global scale processes since silicates constitute about 83% of the rocks exposed at Earth's land surface On geological time scales, atmospheric carbon dioxide content has been balanced by the weathering of Ca - Mg - silicate rocks, the burial and weathering, organic matter and degassing of volcanoes as mentioned in this paper.

The effect of gross primary production, net primary production and net ecosystem exchange on the carbon fixation by chemical weathering of basalt in northeastern Iceland
TL;DR: In this paper, the authors defined and interpreted the annual dissolved inorganic carbon flux in selected river catchments in North Eastern Iceland and compared the spatial distribution of various vegetation communities and their gross primary production (GPP), net primary production, and net ecosystem exchange (NEE).

Behavioral differences between weathering and pedogenesis in a subtropical humid granitic terrain: Implications for chemical weathering intensity evaluation
TL;DR: In this article, a granitic regolith profile in a subtropical monsoon climate-dominated region (southeast China) was used to evaluate the chemical weathering intensity of regolith profiles and siliciclastic sediments.

The geochemical behavior of Cu and its isotopes in the Yangtze River
TL;DR: The anomalous Cu isotope geochemistry of the Yangtze River is attributed to two key features of the basin: first, the influence of the Three Gorges Dam (TGD), and second, the presence of extensive Cu sulphide deposits close to the lower reaches of the river.

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.
