The arcuate Worumba Anticline (Spry, 1952) is a major regional structure centred some 20 km east of Hawker (Fig. 1).- Its eastern flank is gently dipping, and comprises the Sturtian to early Marinoan Umberatana Group, (while the Torr.ensian>to...

Uneconomic stratiform copper mineralization over area of 2.5 by 1 km was discovered by Utah west of Eurelia in 1969 - 1977. It occurs near core of SW plunging anticline in the Burra Group. Host rocks are carbonaceous and pyritic siltstone, dolomite,...

Report gives a detailed justification for the author's recently made proposal to erect three members of a new "supergroup" classification level within the published stratigraphy for the Adelaide Geosyncline, an idea which is based purely on observed...

Summarises information gathered during mapping since 1981, particularly work by Utah Development Company. Covers fault - bounded structural complexes in the Callanna Group and sections measured through upper Burra Group, overlying glacial beds and...

Depot Creek is one of few localities with sedimentary contact between the Burra and Callanna Groups. The Depot Creek 1 drillhole [TD 874.35 m] provided subsurface control for making an interpretation of the structure of the eastern margin of the...

The diapir forms the core of large domal structure and contains large rafts of Sturtian sediments and Willouran dolerite in brecciated matrix. Surrounding country rock, with steep overall dip away from the diapir, comprises Sturtian shale, siltstone,...

Stratigraphic sections were measured through the Callanna Beds and lower Burra Group, by tape and air photo enlargement, at the following localities: (1) north-east of Kingston Dam, (2) south-east of Dome Hill and (3) west of Callanna Homestead. At...

The Arkaroola and Curdimurka Subgroups of the Callanna Group (late Precambrian) are defined respectively in the Arkaroola and Willouran areas. The Curdimurka Subgroup is the uppermost of these subdivisions; it comprises 4700 m of sediments that were...

In southern South Australia, the meridional Torrens Hinge Zone, at approximately longitude 138º, separates the cratonic Stuart Shelf with its undeformed, relatively thin sedimentary cover in the west, from the folded Adelaide Geosyncline to the east....

The core complex contains carbonate breccia and raft like inclusions of rocks including dolerites. These have distinct magnetic signature and associated gravity effects. Gravity surveys have revealed steep regional gradient characteristic of basement...

The Flinders and Mount Lofty Ranges of South Australia contain well exposed late Proterozoic and early to middle Cambrian dominantly sedimentary rocks, deposited in the Adelaide Geosyncline and deformed during the Cambro-Ordovician Delamerian Orogeny;...

Investigation of the Upalinna Diapir, located 20 km east of Wilpena Pound in the Adelaide Geosyncline, has identified a number of structural and sedimentary features normally associated with evaporite diapirs. The Upalinna Diapir is a small,...

Contains summarised geological logs of 93 diamond drillholes and 4 percussion drillholes that were drilled by SADM/SADME and by exploration companies, including the logs of 2 early water bores drilled near Port Pirie. The holes penetrated Cambrian,...

Pre-Mesozoic rocks are best exposed in the Willouran Ranges SW of Marree, but inliers occur as far west as Stuart Creek. These approximate the junction of the Stuart Shelf (to the west) with the Torrens Hinge Zone, which extends east to the Norwest...

Thirty-five thin sections prepared from stored North Broken Hill drill cores indicate that conglomeratic sandstones classified as Emeroo Subgroup, and red siltstones classified as Callanna Group, could alternatively be lateral equivalents of 1 major...

The Adelaide Geosyncline contains an extremely thick folded Late Proterozoic to Middle Cambrian sequence deposited initially in rifted troughs and later in broad zones of regional subsidence. Age constraints on deposition are based on dating of rare...

The OLARY map area includes the SW part of the Willyama Inliers and surrounding Adelaidean (Late Proterozoic) sequences. The Early Proterozoic Willyama Supergroup is separated by NW-trending faults into blocks of metasedimentary rock of upper...

In on-ground exploration of an area on the Stuart Shelf located 18-46 km north-east of Olympic Dam, possible economic sedex - style, Mount Isa / Nifty type stratabound copper was targeted within Neoproterozoic carbonate rocks as part of multiple...
