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:

Inclusion of the weathering of volcanic rocks in the geocarbsulf model
TL;DR: In this article, the carbon cycle model GEOCARBSULF is extended by dividing the weathering of silicates into volcanic and non-volcanic rocks, and the proportion of volcanic weathering is calculated as a function of time from the oceanic record of 87Sr/86Sr.

Mountains, erosion and the carbon cycle
Robert G. Hilton,A. Joshua West +1 more
TL;DR: In this paper, the authors examined the mechanisms of carbon exchange between rocks and the atmosphere, and discussed the balance of CO2 sources and sinks, and demonstrated that organic carbon burial and oxidative weathering, not widely considered in most models, control the net CO2 budget associated with erosion.
Journal ArticleDOI
Potential and costs of carbon dioxide removal by enhanced weathering of rocks
TL;DR: In this paper, the authors provide a comprehensive assessment of economic costs, energy requirements, technical parameterization, and global and regional carbon removal potential for carbon removal, focusing on the grain size and weathering rates.

Evolution of carbon cycle over the past 100 million years
Gaojun Li,Henry Elderfield +1 more
TL;DR: In this paper, the authors proposed that tectonic uplift may have enhanced the sink of atmospheric CO2 by silicate weathering, and thus produced the decline of pCO2.
Journal ArticleDOI
Chemical weathering, mass loss, and dust inputs across a climate by time matrix in the Hawaiian Islands
TL;DR: In this paper, the authors measured the total mass loss and rate of chemical weathering from three minimally eroded, Hawaiian lava flows that are ∼10, 170, and 350 ka old.

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
Journal ArticleDOI
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.
