This 'basement' geology interpretation drew extensively on published 1:100 000, 1:250 000 and smaller scale regional geological
maps and analysis of grids of regional aeromagnetic data with line spacings between 100m and 1.5km from Geoscience Australia's
aeromagnetic database. Bouguer Gravity and bore hole data were also used to complement the interpretation. Flat lying Cenozoic
and Mesozoic cover materials have been removed across the map area; and Paleozoic sediments have also been removed in the
Mount Isa area in the west (north of the Diamantina Fault or northwest of the Thomson Fold Belt). The digital data that accompanied
this map contains lithostratigraphic units compiled at 1:1 000 000 scale. The approximate 900 mapped units are described in
the Australian Stratigraphic Units Database housed in Geosciences Australia in Canberra. The hard copy map presented here
is simplified from the digital data to show the distribution of major lithology groups of different ages. The user is encouraged
to use the digital data for more information. Geological interpretation and compilation by S.F. Liu (Geoscience Australia),
2007-2008, with contributions from I.W. Withnall, L.J.Hutton (Geological Survey of Queensland), D. Champion, G.Gibson, and
D.Huston (Geoscience Australia). Related Products <a href="https://www.ga.gov.au/products/servlet/controller?event=GEOCAT_DETAILS&catno=65992">Basement
