weathering and kinetics Flashcards
microbial weathering
chemical
minerals formed under different P-T conditions that they are weathering
water, O and reactants present =weathering
microbial weathering
how fast will it weather
how far away it is from equilibrium
further away fast weathering
faster at higher temp
mineral composition and structure
microbial weathering
ligand promoted dissolution
complexation of mineral surface cations by ligands
complexing a cation that is part of a mineral it destabilised the bond and breaks mineral apart
ligands have teeth
more teeth
stronger complexation
help dissolution
microbial weathering
what can promote mineral dissolution
ligands or acids
complex atoms on mineral surface and break bonds
microbial weathering
complexation of cations can
lower SI of solution
dissolution indirectly
Microbial kinetics
