Assessment of suitability for age determination by means of uranium lead isotope ratios in zircons. The rocks described include andesite, dacite, trachyte, rhyodacite and rhyolite.

Drillhole 83KD1A completed by CRA Exploration Pty Ltd In the eastern Polda Basin intersected 793 m of interlayered amygdaloidal basalts and evaporite-bearing reddish-brown mudstones below Carboniferous-Permian sediments. K-Ar geochronology and...

2 distinct groups of basaltic volcanoes constitute a western extension to the Newer Volcanics of western Victoria. The older Mount Burr Range group include 14 fissure controlled centres with lava flows, composite domes and cones and tuff rings or...

21 specimens of volcanics and felsic gneisses are heterogeneous in both original lithology and the extent of metamorphic and metasomatic alteration. Strong granitic metasomatism may indicate concealed granitoid plutons. Continuation of andesitic...

The Kanmantoo Trough is the sedimentary and tectonic link between the Adelaide Geosyncline, and volcano - sedimentary sequences of the Tasman Fold Belt. Cambrian Flyschoid sediments were likely deposited on a marginal shelf, reflecting tectonic...

Surficial sediments are predominantly bioclastic, cool-temperate carbonates. Benthic foraminifera Elphidium crispum', a shallow water species, and 'E. macelliforme, favouring deeper water, provide useful numerical ratio which correlates with water...

Background The establishment of a potassium-argon dating laboratory at Amdel was initiated in 1969, with the South Australian Department of Mines providing financial assistance towards the purchase of equipment and continuing operational support in...

37 000 tonnes of gold-copper ore have been produced from the Kitticoola Mine in five phases of mining during its 150 year history. 30 000 tonnes were mined as gold ore, yielding 162 560 grams of gold at an average grade of 5.4 grams/tonne. 7 000...

For a project to determine the base metal potential of known copper-mineralised igneous rocks which outcrop in an area located approximately 59 km south-west of Olary, the South Australian Government has completed detailed mapping, geochemical...

A minimum metamorphic age of greater than 2400 Ma is inferred for two banded iron formations outcropping within the TARCOOLA 1:250 000 mapsheet area. The age obtained is considerably greater than that of the mid-Proterozoic Middleback Group, with...

At the Anna Coalfield, the November 1976 appraisal drilling by SADME of 2 rotary mud, partly cored vertical boreholes with a total penetration of 159.62 m (including 28.36 m of continuous ?NQ coring over the coal-bearing section) has confirmed the...

During September-December 1976, Murnaroo 1 was drilled by the SA Department of Mines to TD 627.5 m near Observatory Hill in the central southern part of the Officer Basin, to investigate the local subsurface stratigraphy and economic potential, and...

The Quaternary stratigraphy in the trench was examined within the Strzelecki dunefield near Montecollina Bore, near Big John Creek and to the south (mainly Balcanoona). Longitudinal and transverse dune sands demonstrated a history of episodic dune...

Following the drying of the very extensive Tertiary lakes, there were 3 complex Pleistocene climatic cycles, or portions thereof, reflecting changes in the world climate related to glacial / interglacial episodes. Describes and interprets 4...

As part of studies on Stratigraphy and chronology of coastal Quaternary sediments in SA, M. vertebralis was dated using radiocarbon 3 and amino acid racemization dating. Results suggest reef connecting Wardang and Goose Islands, rather than being...

Late Archaean / Early Proterozoic foliated massive granites, adamellites and granodiorites of the Dutton Suite (Sleaford Complex) probably represent Sleafordian Orogeny intrusives. Price Island and Golden Island are composed of metasiltstone...

Description of major stratigraphic and lithologic units from Archaean Sleaford Complex to Quaternary sediments, including associated granitoid suites, and their geological evolution. The geochronology and possible stratigraphic correlations of some...

Covers publications from 1960 to 1984. Main source was Bibliography and index of geology and AESIS Vax computer. INMAGIC software was used for compilation and printing. Main entries are in alphabetical order of first named author, with author and...

SADME stratigraphic drilling, which was undertaken recently based on detailed geophysical modelling of aeromagnetic data, has identified the major linear aeromagnetic anomaly associated with the Karari Fault Zone (NW Gawler Craton) as a major (300 km...
