Vertical magnetometer and gravity meter traverses have been run over anomalies disclosed by aeromagnetic surveys near Cowell on Eyre Peninsula. The presence of a very large quantity of magnetic rock, denser than the surrounding rocks and thus...

Excavation of three backhoe pits has confirmed the presence of calcreted bedrock at an average depth of 0.3 m beneath the site. It is considered that this will provide a suitable bearing horizon. Rotary drilling, based on results of a gravity survey,...

Aim was to locate 3 anomalies more precisely to assist in location of drill sites test for mineralization. The results in 2 of the areas indicate anomalies are caused by narrow bands of magnetic material. The source of the anomaly in the third area...

A proposed Primary School will be constructed on thinly covered limestone in an area near caves and sinkholes. To avoid siting buildings on collapsible areas, a 601 station gravity survey was conducted on a 5 m grid. No near-surface voids were...

An interpretation of the results of detailed gravity surveys and of drilling data obtained from stratigraphic drillholes Tickera DDH 1 and 2 and Wokurna DDH 1 - 3 indicates that basement consisting of metamorphic rocks subcrops shallowly west of the...

A narrow possibly fault-bounded trough in crystalline basement, splits and shallows with 1 branch ending abruptly against shallow basement. The other branch may also end 20 km further north, or may continue towards Indooroopilly Outstation. Shallow...

Geophysical and geological surveys plus test drilling have located a Tertiary palaeochannel incised within Cambrian-Precambrian bedrock. Present data indicate potentially favourable reservoir and seal conditions, although its headward extent and...

Ooldea 3 diamond drillhole is located on the western margin of the Gawler Craton where thin Tertiary (ca. 16 metres) and Palaeozoic (ca. 75 metres) sediments, of the Eucla and Officer Basins respectively, overlie Archaean to Early Proterozoic basement...

Nilpena deposits comprise no. 1 and 2 lodes and Jim Crowe lode on the western flank of the Flinders Ranges. The no. 1 and 2 lodes cross cut Brachina Formation on the western limb of the Nuccaleena Dome, whereas Jim Crowe lode has been emplaced along...

The subject exploration licence was taken up for a 1-year term to enable ETSA and SADME to jointly conduct exploration for possible Triassic coal basins that might be concealed beneath alluvial cover in sparsely drilled areas to the north and...

The geomorphology of DALHOUSIE broadly consists of stony uplands which include mound springs in the west, and dunefield lowlands in the east on the edge of the Simpson Desert. Strongly folded ?Adelaidean sediments are overlain by a more gently folded...

Surveys aimed to assist hydrogeological investigations. Large negative gravity feature is interpreted to be granite.

Gravity traverses completed over the Blinman Dome indicate the presence of a low density body, interpreted to consist of brecciated material with a large depth extent. The bulk of the dismembered sedimentary rafts and xenoliths may be confined within...

The probable extent of excavation prior to infill of various materials was delineated at an old clay pit including areas with apparently high concentrations of ferro-metallic debris along with a deeper section of relatively uncompacted material....

This is a compilation of available geophysical data and review of interpretations of the Everard Thrust. It includes regional distribution maps of the Cambrian, Ordovician, Devonian and Permian rocks. Geophysical and geological interpretations pre...

The CHOWILLA 1:250 000 map area lies in the north-western part of the Murray Basin, between latitudes 33° and 34°S and longitudes 139°30' and 141°E. Its eastern boundary is the South Australian - New South Wales state border. The area includes...
