Web17 aug. 2024 · Summary. Lithium isotopes are a relatively novel tracer of present and past silicate weathering processes. Given that silicate weathering is the primary long-term method by which CO2 is removed from the atmosphere, Li isotope research is going through an exciting phase. We show the weathering processes that fractionate dissolved … Web9 jul. 2024 · Initially, smectite domains dominate and contain subparallel layers of variable thickness. As the transition proceeds, abundant dislocations provide avenues for diffusion of both necessary reactants (K and Al) and products (Na, Si, Fe, Mg); illite packets grow within a shrinking matrix of smectite. Web10 dec. 2024 · Relatively large specific surface area and the occurrence of interlayer space of smectite likely results in Li adsorption capacity higher than kaolinite. Under conditions with excess Na + (0.5 M NaCl), smectite Li coverages drop dramatically, while the surface Li loads of smectite and kaolinite are comparable under the same condition (Table 4). simons cat stl
