- •
Phyllosilicate mineralogy differ significantly between particle-size fractions.
- •
No clear relation between phyllosilicate mineralogy and organic C was observed.
- •
Stable clay-size aggregates likely contribute significantly to SOC protection.
- •
Adsorption and entrapment both contribute to C stabilization in clay-size fractions.
- •
This prevents to find a simple relation between clay mineralogy and C stabilization.
