Description :
The AA. suggest a property-based classification system linked to genetic processes. They use enduring micromorphological properties, and also proxy criteria (total chemical analyses) to help classify paleosols that have changed markedly or have been lithified during or after burial. Their system clearly separates paleosol taxon names from those of all ground soils. They use the prescript paleo- at the order level, and kryptic to designate the buried, enduric to designate the relict, lithic to designate the lithified, and emergent to designate the exhumed paleosol suborders. They use prescript modifiers to describe the physical characteristics of the paleosols and postcripts for parent material origin and the extensiveness of the paleosol landscape.
