Worldwide distribution of continental rock lithology: Implications for the atmospheric/soil CO2 uptake by continental weathering and alkalinity river transport to the oceans [PDF]

open access: yes, 2003
The silicate rock weathering followed by the formation of carbonate rocks in the ocean, transfers CO2 from the atmosphere to the lithosphere. This CO2 uptake plays a major role in the regulation of atmospheric CO2 concentrations at the geologic ...

Rock organic carbon oxidation CO2 release offsets silicate weathering sink

open access: yesNature, 2023
Mountain uplift and erosion have regulated the balance of carbon between Earth’s interior and atmosphere, where prior focus has been placed on the role of silicate mineral weathering in CO_2 drawdown and its contribution to the stability of Earth’s ...

Soil Depth Prediction Model Using Terrain Attributes in Gangwon-do, South Korea

open access: yesApplied Sciences, 2023
Soil depth is a crucial parameter in slope stability analysis in mountainous areas. The drilling survey is the most reliable method for determining soil depth, but it requires a high cost for the vast geographical area.

Effect of sedimentary heterogeneities in the sealing formation on predictive analysis of geological CO2 storage [PDF]

open access: yes, 2019
Numerical models of geologic carbon sequestration (GCS) in saline aquifers use multiphase fluid flow-characteristic curves (relative permeability and capillary pressure) to represent the interactions of the non-wetting CO2 and the wetting brine. Relative

Integrated geophysical and geological investigations applied to sedimentary rock mass characterization

open access: yesAnnals of Geophysics, 2008
The Salento Peninsula (south-eastern Italy) is characterized by sedimentary rocks. The carbonatic nature of the rocks means they are affected by karst phenomena, forming such features as sinkholes, collapsed dolines and caverns, as a result of chemical ...
