A regional gravity low occurring south of Round Hill on the ORROROO 1:250,000 sheet was mapped in detail by closely spaced gravity stations, to investigate its possible connection with diapiric breccia located nearby. The suggested model for the...

Survey between Nectar Brook reservoir and Redcliff Point over the proposed Redcliff petrochemical plant indicates that a narrow valley, filled with up to 200 metres of low density sediments, occurs beneath the western portion of the site. Subsidence...

Results of a seismic refraction and gravity survey conducted in the southern portion of the Walloway Basin suggest that its western margin is influenced by faulting. The survey has also indicated the position of a fault which controls groundwater...

Gravity data from a new major helicopter gravity survey and aeromagnetic and seismic data from TALLARINGA and adjoining map sheets is interpreted. The view that the positive gravity anomaly in the Tallaringa Trough is due to dense dolomitic rocks is...

Production was 125 tonnes in 1987 from 2 open cuts. Barite formed in steep fracture zones which cut the bedding of the enclosed siltstone and carbonate rocks of the Wonoka Formation. The white coarsely crystalline barite is iron rich, siliceous and...

Problems associated with the mining and combustion of coal from the Bowmans deposit have led to the search for a viable alternative. 1 potential area lies to the north of the Bowmans and Whitwarta deposits. A gravity survey designed to outline pre...

2 small vertical lodes which cross cut dolomite, contain inferred reserves of 1100 tonnes of oil drilling grade barite. Selective mining should also yield industrial grade, if deeper barite is less iron stained. Neither lode has been worked.

Readings along 5 traverses confirmed the presence of the Burnside Fault which was an interpreted throw of some 300 metres in this area.

Production 1978 - 1985 has averaged $25 000 000 per year. Mining is now mainly by mechanized methods in underground workings, most of the older shallower fields having been worked out. All areas of deeply weathered Bulldog Shale, or Russo Beds...

Geophysical surveys at the City Council Depot site, delineated the extent of large depression, used as rubbish dump. Abrupt lateral terminations of volcanic ash and tuff sequence were correlated with the boundary of the depression. No solution...

Depot Creek is one of few localities with sedimentary contact between the Burra and Callanna Groups. The Depot Creek 1 drillhole [TD 874.35 m] provided subsurface control for making an interpretation of the structure of the eastern margin of the...

Survey was located on 7 seismic lines. Gravity interpretation indicates deep basement structure associated with Precambrian sediments. Features within the Tertiary - Cainozoic units are delineated. Further work is recommended to investigate possible...

598 new stations were established in 1987 gravity survey. It revealed 5 gravity anomalies with potential for underground storage targets. Seismic reflection is recommended over 4 of these areas to establish correlation between the gravity method and...

The Barabba Gravity Low in the Northern Adelaide Plains has been interpreted as a southerly dipping trough-like depression in Precambrian bedrock, infilled with Tertiary and covered by a blanket of Quaternary sediments. All margins of this feature are...

A gravity survey was conducted adjacent to a dump for industrial waste near Callington, to determine basement topography and its effect on the flow of contaminated water from the dump. The results indicate that the most probable flow direction near...

Geophysical and geological surveys and drilling in the Northern Adelaide Plains of South Australia have located a Tertiary palaeochannel incised within Proterozoic bedrock. Present data indicate favourable reservoir and seal conditions for the...

At Howard Lode, adjacent to the extreme SE corner of the Oraparinna Diapir, barite infills steeply dipping fractures within Sturtian Yudnamutana Subgroup. Sediments have been folded around the diapir, and barite veins are parallel to the axial plane...
