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

, 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

Rare earth elements in clay-sized fractions: Implications for weathering fingerprint from parent materials to soils

Geoderma
Rare earth elements (REEs) have gained attention as tracers of pedogenic processes over the last few decades. Clay-sized fractions (CSFs, < 2 μm) may play a crucial role in hosting REEs. To better understand the pedochemical signals of REEs in clay-sized
