ABSTRACT
Explanatory notes for the 1: 500 000 Cobar regolith landform
map (includes one map)
Gibson, D.L.
These notes are designed to accompany the Cobar 1:500 000 Regolith
Landforms map, first published as a hardcopy form by CRC LEME in
1996, and subsequently revised (new polygon symbols and reference)
and published in digital and hardcopy form in 1999. The Cobar region
is well endowed with mineral resources, but geochemical exploration
is hampered by poor bedrock outcrop in low relief, regolith dominated
terrains. The map is designed to show broad regolith-landform units,
giving a valuable regional overview of the main regolith types and
their associated landforms. This is of use to mineral explorers
in the region wishing to place their tenements within the broad
regional regolith-landform context, and also giving a general outline
of the major areas of bedrock or regolith dominated terrain. It
also highlights areas where further regolith investigations might
be carried out.
These notes include ideas on the origin of features of the regolith
and landscape in the area, an expanded description of the regolith
landform units shown on the map, and a bibliography of relevant
published material. Appendices include a table of new and old map
symbols, and an extensive compilation of synopses of published descriptions
of regolith materials in the region, arranged by map areas.
