We show that it is feasible to eliminate the energy-demanding requirement for milling rocks to fine particle sizes. Co-benefits of enhanced rock weathering include substantial mitigation of nitrous oxide, the third most important greenhouse gas, widespread reversal of soil acidification and considerable...
Intensification of the Asian monsoon and a chemical weathering event in the late Miocene–early Pliocene: Implications for late Neogene climate change Several sedimentary, geochemical, and isotopic records indicate that the hypothesized intensification of the Asian monsoon at about 8 Ma triggered a ...
The safety valve that prevents excessive atmospheric pCO2 levels is the triggering of silicate weathering of continental areas and basaltic provinces in the temperate humid belt. Increase in Mg/Ca ratio of seawater over the Cenozoic may be due to weathering input from continental ...
the weathering process of the Bukit Timah granite is extensive and rapid. The large amount of rainfall combined with relative high temperature facilitates the weathering of the bedrock to a vertically varying degree, and the regional nature of bedrock and climatic and topographic conditions result in...
2016). In general, hydraulic conductivity decreases with depth below surface since weathering effects declines on deeper levels together with reduced fracture apertures since rock stress increases at greater depths (Gustafson 2012). As a result, the bedrock is assumed to be more conductive at its ...
Modulation of Late Cretaceous and Cenozoic climate by var- iable drawdown of atmospheric pCO2 from weathering of basaltic provinces on con- tinents drifting through the equatorial humid belt. Clim. Past 9, 525-546. http://dx. doi.org/10.5194/cp-9-525-2013....
Geohazards in the three Gorges Reservoir Area, China – Lessons learned from decades of research 2019, Engineering Geology Citation Excerpt : Fluvial erosion, excavation and differential weathering represent important factors in the formation of rock avalanches in the TGRA. Under the effect of these ...
Modulation of Late Cretaceous and Cenozoic climate by variable drawdown of atmospheric pCO2 from weathering of basaltic provinces on continents ... The small reservoir of carbon dioxide in the atmosphere (pCO2) that modulates climate through the greenhouse effect reflects a delicate balance between lar...
The assumption of an initial period of open system weathering requires substantial organic carbon oxidation in only 4 of the 21 analyzed ice bodies. If the subglacial environment is assumed to be closed from any input of atmospheric gas, large organic carbon inputs are required in nearly all ...
