In a search for postulated Tertiary heavy mineral sands marine placer deposits that may have been formed outside of the presently known north-eastern extent of such age sedimentary basins (i.e. along a proto Eucla Basin coastline existing within the...

Exploration for trona and base metals was centred on the Marla region. Work included regional gravity and magnetic studies, acquisition of airborne magnetic and multi-channel radiometric data, with follow-up ground magnetic and gravity surveys,...

Utah Development Co. entered into a joint venture exploration programme with Northland Minerals Ltd in the Kapunda area of South Australia that has lasted from 29 May 1974 to 14 February 1978. Utah has managed this programme, which sought stratiform...

Exploration for possible buried roll-front or sandstone type sedimentary uranium deposits was carried out over a broad area lying northeast of Lake Frome by a South African - French joint venture. A large reconnaissance open hole rotary drilling and...

A palaeochannel system exists incised into Proterozoic metamorphic and igneous rocks in a NS direction through the eastern portion of EL 121, but no anomalous radioactivity is present.

Orientation geochemical sampling, and 1:25,000 scale geological mapping that included long sectional mapping of four railway cutting bedrock exposures in the Eudunda area, revealed pervasive low grade stratiform copper mineralisation in Sturtian...

Five open rotary holes totalling 614.7 m were drilled and geophysically logged to test a possible, resistivity - interpreted southern extension of the Lower Tertiary Yarramba Palaeochannel. The existence of this additional channel was confirmed, but...

The Cenozoic Eucla Basin is located on the southern margin of the Australian continent, with a present-day basin onshore edge which extends for over 2,000 km from Western Australia into South Australia. The basin’s sediment fill comprises a thin...

TARGET: Possible Tertiary marine placer deposits of heavy mineral sands (ilmenite, rutile, zircon) on the south-eastern margin of the Eucla Basin in the Nunjikompita - Hiltaba area, 100 km east of Ceduna. EXPLORATION: A consultants' photogeological...

The great majority of lower Palaeozoic rocks in the Stansbury, Arrowie and Warburton Basins are of Cambrian age, although a few Early Ordovician fossils have been reported from drillholes in the sub-surface Warburton Basin. The Cambrian is the only...

On the NE margin of the Nullarbor Plain in western SA are preserved coastal dunes, dune ridges and possible beach ridges. The longest is the Ooldea Range, a 650 km long coastal dune that lies 25-300 km from the present coast. These coastal aeolian...

Ongoing exploration for economic buried stratiform copper mineralisation within a small area located 97 km east of Lyndhurst under renewed tenure has consisted of detailed, 1:1000 scale geological mapping and surface geochemical sampling, plus...

Concealed basement on GILES comprises ?Archaean to Palaeoproterozoic metamorphic rocks belonging to the Nawa Subdomain of the Gawler Craton. These are intruded by Mesoproterozoic Hiltaba Suite granitic bodies and Mesoproterozoic or Neoproterozoic...

Shallow Precambrian crystalline basement underlies the greater part of the BARTON 1:250 000 map area. Thicker Neoproterozoic, Cambrian and Carboniferous Permian sediments occur in the northwest, with the southern margin bounded by the Karari Fault...

The CHILDARA 1:250 000 map area is located on the western Gawler Craton, an ancient crystalline shield comprising Archaean, Palaeoproterozoic and Mesoproterozoic metasediments, volcanics and granites that has been tectonically stable since 1450 Ma...
