文摘

Deccan palaeosols were analyzed using XRD, near- and mid-infrared spectroscopy. The evolution is the transformation of celadonite into vermiculite then smectites. The Deccan bole beds stratigraphy is similar to that of Mawrth Vallis, Mars. Mineral paragenesis in Mawrth Vallis may result from shifts in formation processes. Processes include deuteric to low-temperature weathering with limited ion loss.
