A new simple approach to evaluate pedogenic clay transformation in a Vertic Calcisol

Environmental significance of mineral weathering and pedogenesis of loess on the southernmost Loess Plateau, China

“…3) exhibited the presence of illite (peaks around 1.0 nm), poorly crystallized smectite and illite-smectite mixed layers (weak and broad peak between 1.7 and 1.8 nm) (Territo et al, 2006) and traces of quartz (tiny peak at 0.425 nm). The peak at 1.4 nm was attributed to vermiculite (or hydroxyl-interlayered mineral (HIM) and vermiculite) and chlorite because the 1.4 nm peak decreased and shifted to lower d-spacing resulting in the increasing intensity of the 1.0 nm peak after K-25°C and a peak at approximately 1.4 nm stayed after K-550°C (Fig.…”

Characterization of Clay Minerals in Brown Forest Soil Profiles (Luvisols) of the Cserhát Mountains (North Hungary)

“…Pedogenic clay minerals form dynamic systems. Based on their alteration from one to another species, the direction of the weathering process is predictable (TERRITO et al, 2005).…”
