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:

Behaviour of Li isotopes during continental weathering: the Bidar laterite profile, India☆
TL;DR: In this paper, a lateritic profile developed upon the Deccan Traps flood basalt was used to improve our understanding of basaltic weathering by analysis of trace elements and Li isotopes.

Chemical weathering in the Krishna Basin and Western Ghats of the Deccan Traps, India : Rates of basalt weathering and their controls
TL;DR: In this paper, the chemical and silicate weathering of the Deccan Trap basalts, India, have been determined through major ion measurements in the headwaters of the Krishna and the Bhima rivers, their tributaries, and the west flowing streams of the Western Ghats, all of which flow almost entirely through the deccan basalts.

Quantitative models for pedogenesis — A review
TL;DR: In this article, a review of factorial, energy, and mass-balance models of soil formation and evolution is presented, along with some criteria for pedogenesis models and possible integration of the factorial and energy models.

The Sturtian ‘snowball’ glaciation: fire and ice
Yves Goddéris,Yannick Donnadieu,Anne Nédélec,Bernard Dupré,Céline Dessert,Aline Grard,Gilles Ramstein,Louis François +7 more
TL;DR: In this paper, the authors show that the weathering of a 6×106 km2 basaltic province located within the equatorial region is sufficient to trigger a snowball glaciation, assuming a pre-perturbation PCO2 value of 280 ppmv.
Global CO2-consumption by chemical weathering: What is the contribution of highly active weathering regions?
TL;DR: In this paper, a global CO2-consumption model, trained at high-resolution data, is applied to a global vector-based lithological map with 15 lithological classes.

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.
