Below this depth, the vadose zone material is described as being coarse pumice fragment and fines down to the
Palaeosol depth at ~4.2 m (Fig.

Accordingly, polynomial models were fitted to the combined datasets of all Ignimbrite materials (materials 1-4, 7) and the
Palaeosol materials (materials 5 and 6) as documented in Table 3.
The lower lunette was capped with a well-developed
palaeosol, indicating a period of dune stability associated with higher water levels in Lake Tyrrell.
The upper Evangeline Member as seen here has a somewhat different lithological character, largely lacking the intraformational conglomerates, with generally smaller fluvial bedforms and numerous deeply rooted
palaeosols.
These sections, situated within the areas of the maximum advance of the Don, Oka, and Dnieper ice sheets as well as outside the glacial zone, contain key palaeogeographic markers, such as moraines left by these glaciations, loess horizons correlative to them, stratotypic (Likhvin, Chekalin, and others) interglacial horizons of
palaeosols, lacustrine and alluvial sediments, etc.
The
palaeosol layer (1.3-.8m) in the Waihora profile also had a high production rate (6.3E-05 [mu]mol [N.sub.2]O-N/g dry soil.h).
(2000:14) alternatively propose that a large section of the dune had formed by 3000 BP based on their interpretation of
palaeosol distributions and associated archaeological data.
(1994) suggest that the
palaeosol profiles are characteristic of persistent surface aggradation by loess deposition.
Kozur and Weems (2010) interpreted these white to purple strata as a
palaeosol without providing details (Fig.
Examples of relict features are widely discussed in the
palaeosol literature (e.g.
The floodplain deposits and
palaeosol profiles of the Late Carboniferous Cumberland Coal Basin, exposed at Joggins, Nova Scotia, Canada.
