An airborne magnetometer complete with aircraft and crew was retained under contract to conduct surveys over selected areas within the state. A description is given of the equipment layout and of the procedure of reducing the results obtained.

Almost six weeks were spent with the Far North-West party at Granite Downs Station in conducting magnetic and gravity traverses. Work was curtailed before sufficient results could be obtained for an accurate picture of subsurface structure. Gravity...

Ground magnetometer surveys were carried out by the writer over typical portions of the geomagnetic anomalies located at the North Billeroo dam area and adjacent to the Alconie dam to determine their cause. Inspection of these areas showed that the...

A survey with gravity meter and vertical force variometer has been carried out on two aeromagnetic anomalies to the west of the Katunga Hills. The area is covered with sand and alluvium and results obtained indicate the anomalies to be due to varying...

In an area of limited basement outcrop located between 2 and 5 miles north-northwest of Iron Knob township, the Department's surface traverse channel sampling (969'), percussion boring (643’) and diamond drilling (1270’) tested a low grade...

The results of gravity and magnetic surveys over Prospect No. 5 display trends which can be interpreted in more than one way. From results of previous drilling, a number of small gravity anomalies appear to be associated with iron ore, which a larger...

Four different types of geophysical surveys were carried out in the vicinity of the old Talisker Mine in an effort to detect the presence of possible sulphide ore bodies. No conclusive results were obtained due to the lack of penetration of the...

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

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...

The Airborne Magnetic Survey, Upper Eyre Peninsula (Sheet 2) - B.M.R. indicated sixteen magnetic anomalies of intensities >3000 gammas, approximately 1000 gammas above background. To give some indication of overburden depths at eight selected...

Surface lineaments on Landsat imagery within and around the margins of the Cooper Basin show variable density and variable length, but two preferred directions. These are 55 degrees and 305 degrees and correspond to dominant structural directions in...

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...

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 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...

Ooldea 2, located 19 km south of Ooldea Railway Siding, was spudded on 25/9/85. It was sited next to Amoco drillhole ORP1, which had intersected 90 metres of basement gneiss with a composition including hypersthene + sillimanite + quartz, with...

The diamond and base metal potential is appraised based on recent company exploration for gold and diamond bearing kimberlites, with special reference to regional stratigraphy, tectonic structures based on the Echunga detailed low level aeromagnetic...

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...

Based on compilation of basement depth interpretations from previous aerial magnetic surveys.
