Basalt weathering laws and the impact of basalt weathering on the global carbon cycle
TLDR

Addendum to “Inclusion of the Weathering of Volcanic Rocks in the GEOCARBSULF Model”: (R. A. Berner, 2006, V. 306, p. 295–302).
TL;DR: In this article, the compiled data presented by [Dessert and others (2001) for different values of the relative weathering rates of basalts versus granites, was missed.

Lithological influences on contemporary and long-term regolith weathering at the Luquillo Critical Zone Observatory
Heather L. Buss,Maria Chapela Lara,Oliver W. Moore,Andrew C. Kurtz,Marjorie S. Schulz,Art F. White +5 more
TL;DR: In this paper, the authors compared two nearby catchments in the Luquillo Critical Zone Observatory in Puerto Rico, which have similar climate history, relief and vegetation, but differ in bedrock lithology.
Journal ArticleDOI
Towards an Integrated Model of Weathering, Climate, and Biospheric Processes
TL;DR: This paper showed that continental weathering is strongly affected by human activities and showed that the amount of atmospheric carbon being removed through this process has been estimated from the inventory of the amounts of bicarbonate ions carried by the world major rivers.
Journal ArticleDOI
Multiple causes of Earth's earliest global glaciation
TL;DR: In the context of Earth System evolution, the causal factors driving the Palaeoproterozoic Huronian global glaciations occupy a central position as discussed by the authors and major topographical features and continental drainage patterns were most likely similar to those in younger continental flood-basalt provinces and would have enabled deep weathering and erosion of extensive basalt-covered continental areas.

CO2 geological storage: The environmental mineralogy perspective
François Guyot,Damien Daval,Damien Daval,Damien Daval,Sébastien Dupraz,Isabelle Martinez,Bénédicte Ménez,Olivier Sissmann,Olivier Sissmann +8 more
TL;DR: In this article, the authors discuss some environmental mineralogy research perspectives raised by CO 2 geological storage, and discuss the efficiency of the process and its environmental consequences in large-scale CO 2 storage.

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.
Journal ArticleDOI
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.
