Crustal redistribution, crust-mantle recycling and Phanerozoic evolution of the continental crust
TL;DR: In this article, the mass balance of the continental crust during the Phanerozoic and especially the Cenozoic (65 ǫ Ma) was investigated. And the authors found that the seafloor crustal volume may be running a long term loss of 3 /a, meaning that arc production rates could be as low at 2.0 ǔ 0.8 ǒ 0.

Carbon Mineralization: From Natural Analogues to Engineered Systems
Ian M. Power,Anna L. Harrison,Gregory M. Dipple,Siobhan A. Wilson,Peter B. Kelemen,Michael Hitch,Gordon Southam +6 more
TL;DR: Carbon mineralization as discussed by the authors is a natural process that sequesters CO2 by reaction of alkaline earth metal bearing silicate and hydroxide minerals with CO2 to form stable carbonate minerals.

Modelling weathering processes at the catchment scale: The WITCH numerical model
Yves Goddéris,Louis François,Anne Probst,Jacques Schott,David Moncoulon,David Labat,Daniel Viville +6 more
TL;DR: In this paper, a numerical model of chemical weathering in soil horizons and underlying bedrock (WITCH) was coupled with water and carbon cycles in forest ecosystems (ASPECTS) to simulate the concentration of major species within the soil horizon and the stream of the Strengbach granitic watershed, located in the Vosges Mountains (France).

Monogenetic Basaltic Volcanoes: Genetic Classification, Growth, Geomorphology and Degradation
Gabor Kereszturi,Károly Németh +1 more
TL;DR: The origin of the origin of intra-plate volcanic systems has been investigated in this article, where it was shown that small-volume volcanoes with dispersed magmatic plumbing sink-tems that erupt predominantly basaltic magmas derived usually from the mantle with just sufficient residence time in the crust to allow minor fractional crystallization or wallrock assimilation.

Atmospheric carbon dioxide linked with Mesozoic and early Cenozoic climate change
TL;DR: The large decreases in the partial pressure of CO2 coincide with glaciations, providing evidence against climate-CO2 decoupling during the Mesozoic as mentioned in this paper, which is the only known evidence that CO2 levels were variable during the period 200 to 60 million years ago.

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.
