Mount Toondina lies near to the centre of the Arckaringa Basin, herein redefined somewhat provisionally, on seismic evidence, as a significantly thicker development of Upper Palaeozoic sediments. The Mount Toondina Beds are herein formally described....

Stuart Range No.3 bore, which was deepened by rotary drilling during January-March 1965 in a search for additional underground water supplies for the Coober Pedy Opalfield, and which was completed as a stratigraphic bore (with some bottomhole rotary...

An electromagnetic (EM) survey was carried out in the vicinity of the inactive Uley graphite mine in an effort to detect possible extensions of the known graphitic lodes with a view to developing additional open cut areas. Several zones of anomalous...

This report deals with the method that has been adopted in the Mineralogy and Petrology laboratories for the concentration and purification of accessory minerals from granitic rocks. Analytical procedures for the determination of lead and uranium in...

Late in 1957 work was in progress at the Departmental Laboratories on age determination of granites by the zircon method. A letter dated 31 December 1957 from Chief Geologist, Bureau of Mineral Resources, Canberra to the Director stated that the...

Logging of sludge samples taken from 18 water bores drilled in an area of previously unknown stratigraphy located between Watson and Maralinga has established a sequence of about 1000 feet of Marinoan shales and sandstones resting on diorite. These...

Contains a description of the biostratigraphic determinations made on drill cuttings samples recovered from below 1047 feet depth in the subject drillhole. Metamorphic basement rocks were encountered at 1191 feet depth, and drilling ceased at 1260...

Bumbarlow 1 (TD 720.33 m) aimed to test the lithology and petroleum potential of the Cambrian section in the central part of the eastern Arrowie Basin. It continuously cored a sequence over 300 m thick of flat-lying Proterozoic sediments interbedded...

Attempts to date granites and metamorphics within the Outalpa (Willyaman) Inlier of South Australia were made in order to determine isotopic ages of events within the Proterozoic Olarian Orogeny. Two conformable adamellitic to granodioritic gneisses...

Two major Late Proterozoic glaciations, separated by a thick interglacial interval of the order of 3000 m, are recorded in the Adelaide Geosyncline of South Australia. The earlier, Sturtian, succession includes two major glacial phases according to...

Based on regional mapping, preliminary maps are presented. The area contains some of the best exposures of Archaean to Early Proterozoic and critical information on missing link (Middle Proterozoic) between Early and Late Proterozoic evolution of the...

A bottomhole drill cuttings sample obtained from a newly drilled water bore at Seacliff has been examined for the purpose of biostratigraphic correlation of the limestone aquifer sediments. It was determined from foraminiferal species assemblage...

Flow banded, porphyritic acid volcanics (similar in age to the Gawler Range Volcanics) occur on Hart Island. Xenolithic within the volcanics is pink leucogranite, about 1550 Ma. Synchronous with the volcanics are grey, leucocratic alkali granites....

An Eocene age is determined for one sample from Tarcoola TPS-13R bore, a Pliocene age for a sample from Tarcoola TPS-15 bore, and a Plio-Pleistocene age for a sample from Tarcoola TPS-17 bore. A sample examined from Tarcoola TPS-14 bore contained no...

Geology of Lake Superior region outlined. Many similarities in tectonic evolution and depositional style of the 2 provinces. Recommends further research on Gawler Craton.

The intrusives are dominated by granite, N - S oriented diorite dykes up to 50 metres wide, and late stage aplitic and pegmatitic veins with variable orientation. A Middle Proterozoic age is indicated for some of the granitoids, which were probably...

Relative and absolute age of the regolith is emphasized from evidence from the gorge section of the Murray River in the Ngaiwang Folk Province.
