The mixed flora of the Late Cretaceous and Early tertiary which had elements that have now been separated into subtropical/tropical and temperate types, and sclerophyll and mesophyll vegetation.
The study of pollen. Because pollen is extremely resistant to damage by natural processes it can be found and identified in fossilised sediments millions of years old.
Smooth, gently-sloping plain developed in the piedmont zone and meeting the backing scarp in a sharp break of slope or piedmont angle (nick). Covered pediments carry a veneer of coarse introduced alluvial debris, mantled pediments a regolith in situ; in rock pediments or rock platforms country rock is exposed over most of the surface.
Land worn down by erosion almost to a level plain.
kinship division consisting of two or more distinct clans which are considered a single unit, but which retain separate identities within the phratry
The foot of the mountain, the zone of subdued relief at the base of a hill, mountain or massif.
Abrupt change of slope between scarp and pediment., also known as piedmont nick.
Glacier developed at the base of an upland.
Area at the base of an upland or range, the scarp-foot zone.
A dry lake bed - salt lake
Mantle of weathered rock plus any transported material covering the underlying fresh rock. See also grus, soil
Salt-(gypsum or halite) encrusted lake bed.
Movement of particles in a series of jumps driven by the wind or in running water. .
A steep rocky slope. Also termed escarpment.
