Modeling the evolutionary rise of ectomycorrhiza on sub-surface weathering environments and the geochemical carbon cycle
TL;DR: In this article, a process-based soil chemistry model incorporating the effects of plants with ancestral arbuscular mycorrhizas, and more recently evolved ectomycorrhizeas on soil chemistry via its effects on the biological proton cycle was developed.

CO2 Storage Potential of Basaltic Rocks Offshore Iceland
TL;DR: In this article, it is estimated that up to 7000 Gt CO2 could be stored offshore Iceland within the Exclusive Economic Zone, where the most feasible formations are the youngest formations located within the active rift zone.

Does organic carbon sequestration in volcanic soils offset volcanic CO2 emissions
TL;DR: In this article, the authors combine data from available studies conducted on Holocene volcanic deposits in different parts of the world to assess soil organic C accumulation and find exponentially decreasing accumulation rates with increasing soil age, dropping below 10g Cm −2 ǫyr −1 after approximately 1000 years of soil development.

The behavior of metals/metalloids during natural weathering: A systematic study of the mono-lithological watersheds in the upper Pearl River Basin, China.
TL;DR: The results show that the content of transition elements in carbonate rocks are much lower than for shales and basalts, but these metals produce higher enrichment levels in sediments and soils through rapid weathering.

7.6 – Chemical Weathering Rates, CO2 Consumption, and Control Parameters Deduced from the Chemical Composition of Rivers
TL;DR: In this article, the importance of parameters controlling chemical weathering rates should be evaluated and included in climate models, based on the chemical composition of rivers draining both small and large watersheds.

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.
