These deposits acquire the characteristics of
colluvium on the slopes and give rise to a dune relief in the paleoplain.
Regions underlain by unconsolidated Quaternary deposits of glacial, alluvial and lacustrine origin were transferred to nut base map from geologic maps (Huntting et al., 1961; Tabor, 1975) to represent provinces in which rock outcrops and rocky
colluvium are rare.
As the result of this observation is seems to be possible to accurately determine fresh slides together with transport direction of
colluvium sediment.
The Valley 384 m Parry Formation; Carboniferous sediments and Tertiary Basalt
colluvium Property Soil type Fertiliser application l.
Because the failure plane of a slump lies beneath the surface, in either bedrock or
colluvium (weathered material that has moved downslope), determination of the size or even the full extent of a slump can be difficult.
Headwall weathering and thickness of
colluvium suggest a pre-LIA age.
Watersheds are affected by sediment mass budgets in which the important parameters are the inputs (erosion), intrabasinal storage (alluvium and
colluvium), and the outputs (sediment yield).
High conductivity values in 1993 and during the same time period in 1994 suggest that the contribution of dissolved solids in the early season is derived from ion enrichment of snow meltwater that flows through
colluvium and alluvium in the lower basin tributaries.
For poorly defined Cainozoic unconsolidated material, such as unqualified 'alluvium' or '
colluvium' for which their broad composition is unknown, lithological classes were allocated following reference to existing soil type maps.
Loess is followed by a
colluvium of marl and finally by loess.
At Rockvale, soils were developed from New England metasediments of the Sandon Beds, while at Newby Park, soils were developed from a mixture of New England Metasediments (Sandon Beds) and Tertiary Basalt
colluvium from the unclassified Armidale volcanics.
