The Long Ridge granite (informal names Sienna Granite, Sienna Brown and Sedan Granite) is fine to medium grained, probably crystallized under shallow cover. 15 samples are described to illustrate false variation, weathering alteration, fracturing,...

In the search for groundwater over 90 km, 11 potential sites were selected on geological grounds. The Transient EM (TEM) surveys assessed ground resistivity, initially over 2 pre-drilled test areas. Of the other 9 areas, 6 showed favourable...

Geological interpretation from drilling and seismic information, on an Early Palaeozoic sedimentary basin containing Early Cambrian to possibly Devonian age rocks. Middle to latest Late Cambrian sediments (Kalladeina Formation) and probable Cambrian...

Special attention was given to the influence of petrographic features on the quality of the rock as a dimension stone. The specimens included granodiorite, adamellite and granite. Foliation varied from moderate to absent. 5 categories of fractures...

Middle Proterozoic red granite is quarried near Calca, 35 km SE of Streaky Bay on western Eyre Peninsula. It is ideally suited as dimension and monumental stone, being fresh, uniform in texture and colour, and comparatively free of defects. It is...

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 quarry plan, designed to yield 100,000 cubic m of in-situ material, has been outlined in a microgranite outcrop on Eyre Peninsula which is located 15 km east of Cummins and 10 km south-east of the Uranno railway siding. Diamond drilling (3 inclined...

The southern portion of the Mount Painter Inlier contains large volumes of granitic breccia of uncertain origin. 3 vertical exploratory diamond drillholes were sited near Mount Gee and Mount Painter to determine the depth of this breccia, and to...

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...

Origin of the colour variation could not be determined by optical petrography.

Zircons from altered granite in basement below the Cooper Basin, between 9353 and 9377 feet, are suitable for uranium - lead isotope dating.

2 varieties of granitoid and 1 altered dolerite in basement inlier have been sheared at low temperature but no evidence of regional metamorphism. Several episodes of shearing have taken place. Zircons from granite are probably suitable for age dating.

129 samples indicate that 4 deformation phases are present within this dominantly gneissic terrain: D1, D2, D3, and D5.

Petrology of 174 rocks indicate that 5 deformation phases (D1 - D5) are present within this dominantly schistose domain. Describes many samples which contain gneissosity, schistosity or crenulation.

Major units present are 2 suites of Middle Proterozoic granite and Middle Pleistocene calcarenite. The older granite suite has an age of about 1585 Ma, while the other suite had intrusive age of 1457 +- 25 Ma. The granites are enriched in K2O and SiO2.

Describes rocks from 3 areas formerly mapped as Flinders Group. Granites in each area are distinctively different, but metasediments are similar.
