Journal ArticleDOI
The weathering and element fluxes from active volcanoes to the oceans: a Montserrat case study
Morgan T. Jones,Morgan T. Jones,Deborah J. Hembury,Martin R. Palmer,Bill Tonge,W. George Darling,Susan C. Loughlin +6 more
TL;DR: The authors examined the impact of recent volcanic eruptions on the geochemistry of pre-existing hydrological systems and demonstrated that the initial chemical weathering yield of fresh volcanic material is higher than that from older deposits within the Lesser Antilles arc.

Chemical weathering under mid- to cool temperate and monsoon-controlled climate: A study on water geochemistry of the Songhuajiang River system, northeast China
Bao-Jian Liu,Cong-Qiang Liu,Gan Zhang,Zhi-Qi Zhao,Si-Liang Li,Jian Hu,Hu Ding,Yun-Chao Lang,Xiao-Dong Li +8 more
TL;DR: In this article, the authors studied the chemical weathering and CO2 consumption of the Songhuajiang Basin in a mid- to cool temperate and monsoon-controlled climatic zone.

The influence of hydrothermal activity on the Li isotopic signature of rivers draining volcanic areas
TL;DR: In this article, the geochemistry and the isotopic composition of lithium (δ 7 Li) of rivers draining volcanic islands (Guadeloupe, Iceland, Java, Martinique and Sao Miguel) with a specific focus on continental hydrothermal activity were explored.

River geochemistry, chemical weathering, and atmospheric CO2 consumption rates in the Virunga Volcanic Province (East Africa)
Charles M. Balagizi,François Darchambeau,Steven Bouillon,Mathieu M. Yalire,Thibault Lambert,Alberto Borges +5 more
TL;DR: Water chemistry data from 13 rivers of the Virunga Volcanic Province (VVP) (Democratic Republic of Congo), sampled between December 2010 and February 2013, was reported in this article.

Tectonic control of continental weathering, atmospheric CO2, and climate over Phanerozoic times
TL;DR: In this paper, the role of continental drift on the Phanerozoic evolution of the carbon cycle and climate with the GEOCLIM numerical model was explored, and it was shown that continental drift is a first order control parameter of the geological carbon cycle.

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

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.
