A project to compare Gawler Craton iron formations of unknown age with those of known Archaean age (from geochronology) and with the Proterozoic, Lake Superior - type Middleback Range iron deposits has concentrated on characterising each formation by...

Veins of barytes, and massive lenses up to 40 feet wide, were deposited within a fault zone trending east-west across a periclinal structure in beds of the Umberatana and Wilpena Groups. The barytes is associated with up to about 3.5% strontium...

3 sets of fault trends are distinguished, representing the Arrowie fault zone and components of the Mount John, Mount Roebuck and Narina fault zones. Small mineral deposits consist of phosphate, barite and copper.

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...

A north-northwest trending basement high or horst-like structure mapped in the subsurface at Yadlamalka, located about 50 km north of Port Augusta, which was indicated by magnetic and gravity data to lie at a depth of about 200 m to 600 m close to the...
