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.
Quaternary paleosols, tephra deposits and landscape history in South Kamchatka, Russia

The AA. aim to clarify the landscape history of the region by assessing the intensity of soil development and therefore the relative age of paleosols formed in these glacial and associated glaciofluvial deposits. Interpretation is complicated
by the periodic deposition of volcanic tephra on top of the paleosols and the occurrence of permafrost during the Quaternary. Both may strongly influence soil formation, especially the intensity of weathering.

This paper discusses the genesis and regional variation of the paleosols of the Ténéré and southern Tchigai Highland. Catenary studies highlight local variations in the soil pattern due to relief, influence of ancient groundwater tables

Profiles with multiple paleosols developed in loess at Kapela-Batajnica and Stalać were studied by chemical, physical and mineralogical methods to determine paleoclimatic changes through the Pleistocene. The cyclic nature of sedimentary
to that of other central European loess-paleosol sites, and the other (Stalać) with a stronger Mediterranean influence.
