Modern, multifold seismic data over the far eastern Officer Basin have been reinterpreted and seven reflectors mapped in time. Parts of six major structural zones are identified in the region: Munyarai Tough, Marla Overthrust Zone, Ammaroodinna...

PEL 41 was granted to a deliberately SA-based new venture exploration company consisting of Chairman and well-known Emeritus Professor of Geology Eric Rudd, four other founding honorary and unsalaried directors, and 100 or so individual speculative...

TARGET: Possible buried base and precious metal deposits associated with aeromagnetic anomalies, and also with either coincident or unrelated gravity anomalies, lying within a relinquished sector of the large contiguous multi-licence area that Western...

Renewed base metal exploration over part of the historic Yudnamutana Mining Field has targeted base metal anomalies previously found by Australian Selection in the Blue mine area. An area of about 80 square miles was assessed by reconnaissance stream...

Ongoing exploration for economic base and precious metals in the Blue mine area at the eastern end of the Umberatana Syncline has comprised detailed, 1:5000 scale prospect mapping, preparation of a preliminary new tectonic and structural analysis...

Newmont Mining used a ground magnetic survey, an IP survey and a soil geochemical survey to select sites at the Mutooroo Ridge copper prospect for its subsequent drilling during May and October 1977 of 2 inclined, percussion precollared diamond cored...

An area surrounding the Emeroo Range, and extending from the vicinity of Port Augusta to 30 km west of Hawker, was explored by Utah for possible economic stratabound base metal deposits which it was thought could be associated with certain favourable...

Intensive shallow RAB and percussion pattern drilling of highly sheared and deformed Early Proterozoic granitoid rocks, seeking economic, low grade but large tonnage Rossing style deposits of vein-type uranium ore, particularly in association with a...

Investigation of basal Adelaidean Callanna Beds metasediments in the vicinity of the Blue mine and Wheal Turner, north of The Needles in the northern Flinders Ranges, sought to disclose possible Zambian type stratiform massive copper sulphides...

Continuing exploration of the basal Neoproterozoic sedimentary sequence in the north-eastern Flinders Ranges for possible economic stratiform/stratabound Kapunda or Blinman - type copper mineralisation has concentrated on detailed 1:1200 and 1:4800...

A geochronological study of clastic metasedimentary units buried in the Delamerian Orogen region of South Australia has been undertaken to gain a better understanding of the age and provenance of these units and to assess their similarities to...

The extremely thick succession provides one of the most complete sedimentary records for the Late Proterozoic. The term geosyncline is used in a non-genetic sense for the basin in which deposition occurred during the Adelaidean and Cambrian. Only the...

This report book presents verbatim Dr Trevor Mount’s 1975 Ph.D. thesis entitled "Diapirs and diapirism in the Adelaide Geosyncline", including his superbly detailed maps, with the addition of some supporting documents of both geological and historical...

Diapiric marbles and dolomitic siltstone breccia of presumed Willouran age intrude younger Umberatana Group rocks which have been folded into an elongate domal structure and, in part, rest unconformably on the diapiric core. Within the diapir several...

Examination of the cores recovered from three diamond drillholes put down to test IP anomalies detected over a basic igneous ?andesitic intrusion in the Willouran Inlier near Spalding, did not reveal the sources of these anomalies, or the source of...

A programme of stratigraphic section measurement is envisaged in order to facilitate rock correlation and help outline the pattern of sedimentation in the Adelaide Geosyncline. In many areas measurement may be made on air photo enlargement, as has...

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...
