The distribution and relationships of Lower Cambrian units in the Flinders Ranges are illustrated by a panel diagram and sketch maps. A new rock name, Hawker Group, is introduced for six formations of Lower Cambrian age which represent a phase of...

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...

A paleomagnetic study of the mid- to Late Cambrian sedimentary rocks in the northern Delamerian fold belt reveals an overprint acquired after regional folding during the Cambro-Ordovician. The paleopole position, based on data from eight sites, is...

14 lines of grid-based IP and resistivity profiling were carried out at the abandoned Ooloo silver-lead mine by contractor McPhar Geophysics, to try to detect any possible subsurface extensions of the mineralised lodes under alluvial cover. Several...

Anzoil NL carried out geological and geophysical studies on previous exploration data, but was unsuccessful in attracting farmin partners either locally or overseas. The licence area was reduced to ease the work commitment, by partial relinquishment...

This section of the study was based on source rock analyses performed on 75 outcrop and shallow drill core samples from 25 localities, plus other new data derived from Cambrian sediments intersected in the deep petroleum exploration wells Moorowie 1,...

Wertaloona Seismic Survey - AIM:The 1981 Wertaloona Seismic Survey programme was designed by the PELs 5 and 6 Arrowie Block partners to provide the first high quality, multifold seismic reflection data in the area of likely preserved thick Cambrian...

Contains results of conventional drill core analysis, of base metal assays of cuttings and cores by AAS, and of source rock analysis of drill cores for extractable organic matter, total organic carbon, description of dispersed organic matter, vitrinit...

Reconnaissance geochemical sampling of the eastern PARACHILNA mapsheet area for sediment-hosted base metal deposits has succeeded in locating several well-defined areas of interest, although approximately two-thirds of the SML area appears to be...

After acquiring an option over Rieck's and other parties' current mineral claims on the Ooloo workings, the surrounding SML 610 operator Petromin searched for possible along-strike extensions to the known lead-zinc-silver mineralisation occurring in...

This gravity survey portion laid out 2870 stations on the Lake Frome Plains, east and north-east of Reaphook Hill, to confirm and determine the extent of a postulated deep structural trough lying adjacent to the eastern flank of the northern Flinders...

During the period January 1946-December 1985 under review, the following petroleum exploration work was carried out over the Arrowie Block: 6 gravity, 2 aeromagnetic and 10 seismic surveys (total seismic coverage 2781 line km), plus 4 wells, all dry....

Frequent ‘shows’ of hydrocarbons in Cambrian strata in South and Central Australia have considerably strengthened the belief in the petroleum potential of these Cambrian sediments. In South Australia, prospects for Cambrian hydrocarbon accumulations...

A review made of the literature covering post-Precambrian volcanism in South Australia has indicated that less well-known, minor, mainly acid to intermediate volcanic rocks of the lower Palaeozoic are separated by a wide time gap from the better known...

The Parachilna 1:250 000 map area is about 250 road miles north of Adelaide, South Australia, and includes the eastern shore of Lake Torrens, the central Flinders Ranges and part of the Lake Frome Plains. The ranges are composed of folded Adelaidean...

The COPLEY 1:250 000 map area includes the northern Flinders Ranges and the southern part of the Willouran Ranges. It is bounded to the west by the Lake Torrens Sunkland and, to the east, by the Lake Frome Plains. A thick sequence of older Precambrian...

Shallow seismic refraction traverses have been carried out at six proposed sites for silt traps upstream of Aroona Dam, near Leigh Creek. The aims of the survey were to determine seismic velocities in the soil and weathered rock overburden, and in the...

Early Cambrian marine sediments in the Arrowie Basin, South Australia, were deposited on a continental margin platform, and have been divided into five unconformity bounded depositional sequences and subsequences, ranging in age from basal Cambrian to...

Cambrian sediments in the Arrowie Basin were deposited on a rifted continental margin. Four distinct depositional regimes, ranging from a western, tectonically stable shelf, through platform-ramp to eastern slope and trough-synclines, can be...
