Abstract:
Efficient utilisation of Landsat imagery in petroleum exploration depends upon methodical gathering of structural and geomorphic data, integration of these data with existing geophysical and geological information,and ultimately the construction of subsurface stratigraphic-structural models. The ubiquitous blankets of Cainozoic aeolian, evaporite and residual deposits which obscure bedrock outcrops over much of central arid Australia may often be turned to advantage through the medium of Landsat interpretation. The shapes and
regional distribution patterns of individual geomorphic units frequently provide indications of structure in the
underlying strata. Detection of minor tectonic disturbances in the regolith is particularly significant since
these are frequently indicative of reactivated bedrock structures. Examples cited to illustrate the general
method are derived from Landsat studies of the Canning, Arckaringa, Ngalia and Officer Basins.
