Modeling the evolution of natural cliffs subject to weathering. 1, Limit analysis approach [PDF]

open access: yes, 2011
Retrogressive landsliding evolution of natural slopes subjected to weathering has been modeled by assuming Mohr-Coulomb material behavior and by using an analytical method.

Variation of Soil Aggregation along the Weathering Gradient: Comparison of Grain Size Distribution under Different Disruptive Forces. [PDF]

open access: yesPLoS ONE, 2016
The formation and stabilization of soil aggregates play a key role in soil functions. To date, few studies have been performed on the variation of soil aggregation with increasing soil weathering degree. Here, soil aggregation and its influencing factors

Vegetation of the gnamma of the Sierra de Guadarrama and La Serena (Spain)

open access: yesAnales del Jardín Botánico de Madrid, 2009
Weathering pits are wetlands of geomorphologic and biological interest, but this common fact is obscured by the different names used by biologists, such as the ambiguous name of rock pool.

The role of hydrological processes on enhanced weathering for carbon sequestration in soils in tropical areas [PDF]

open access: yes, 2020
To mitigate global warming, a noticeable research effort is being devoted to NCS (Natural Climate Solutions) as means to reduce greenhouse gas emissions or sequester carbon within the oceans or terrestrial environments by exploiting natural processes ...

REE fractionation during granite weathering and removal by waters and suspended loads: Sr and Nd isotopic evidence [PDF]

open access: yes, 2001
Very few studies deal with REE (rare earth element) mobility within the system soil–soil solution–streamwater. In this article, we try to characterize the fractionation and the migration of the REE in a granite-derived soil system located in a small ...

Destabilization of carbon in tropical peatlands by enhanced weathering

open access: yesCommunications Earth & Environment, 2022
Enhanced weathering in tropical peatlands may be an ineffective carbon dioxide removal strategy due to pH-induced increases in soil carbon leaching which lead to increased re-emission of carbon, according to model calculations constrained by observations

Increase in cation exchange capacity by the action of maize rhizosphere on Mg or Fe biotite-rich rocks

open access: yesPesquisa Agropecuária Tropical, 2022
The weathering of some silicate minerals in crushed rocks may occur in a few days of cropping and generate different physicochemical properties, with potential benefits to tropical soils.

Impact of nitrogenous fertilizers on carbonate dissolution in small agricultural catchments: Implications for weathering CO2 uptake at regional and global scales [PDF]

open access: yes, 2008
The goal of this study was to highlight the occurrence of an additional proton-promoted weathering pathway of carbonate rocks in agricultural areas where N-fertilizers are extensively spread, and to estimate its consequences on riverine alkalinity and ...
