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...

Experimental seismic work was carried out to delineate an infilled glacial valley development as a safe harbour. Both conventional in-line shallow refraction and broadside shooting were used to obtain a complete profile of the valley. Test excavation...

The experiments indicate conglomerate can be delineated by seismic methods in both natural surface and removed overburden situations. However, confirmation by test drilling is needed. Some modifications to the original method are recommended along...

A seismic refraction survey at Roger Corner, near Yorketown on Lower Yorke Peninsula, has profiled pre-Permian bedrock and several other shallower refractors. The survey was carried out at the request of Aberfoyle Exploration Pty Ltd, licensees of EL...

Aim was to delineate the top of the granite which had been detected in auger drilling. Results show that the granite was probably in the form of boulders as the seismic velocity of the layer containing the granite was extremely low. Some test trenches...

The drill hole on SADME seismic line PB83-001 at shot point 338, within EL1054, aimed to provide correlation between 1983 seismic reflection profile, and the lithological and geophysical logs. Drilling to 1398 metres encountered Miocene, Eocene,...

4 stage exploration programme is proposed to include completion of gravity station network in Saint Kilda, Dry Creek and Torrens Island area, reconnaissance and detailed seismic surveys and detailed stratigraphic drilling to evaluate the South Maslin...

2 seismic refraction profiles aimed to test the method in searching for alluvial channels incised into Adelaidean bedrock in EL1413. Interpreted depths to bedrock of 6-10 metres were confirmed by follow-up drilling and an indication of the bedrock...

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.

Rippability of the near surface material below the low water mark was determined for proposed excavations below a boat ramp. Excavation by backhoe should be possible, but 2 areas may be difficult. Basement depth contours were calculated to indicate...

Geological conditions are suitable for the proposed alignments of tunnel and racechannel.

4 shallow spreads have provided additional basement depth information over possible basement high, as indicated from shallow borehole date over the area. Results indicate a small ridge below spread 3 which extends into the overlying sediments. This...

Drilling within preferred mining area of the deposit was undertaken to obtain coal quality and tonneage data.18,100 mm diameter cored holes (554 metres) and 18 open holes (3138 metres) were drilled to delineate optimum mining area (6529 : 4 MW558 -...

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...

Simple field guide for operators with little experience of the technique, describing some of the pitfalls, errors and misinterpretations with suggested solutions.

Shallow surveys to investigate the subsurface material below 2 potential dam sites indicates that problem areas exist where possible shear zones and basement infills occur. Backhoe pits indicate that in landslide areas, the depth to bedrock may exceed...
