The Officer Basin probably formed when the Gawler Craton collided westerly with the Yilgarn Craton during 1300-1000 Ma; the collision-faulted belt of the Fraser-Musgrave Orogen might form the basement of the Munyarai Trough in the eastern part of the...

In South Australia, the intracratonic eastern Officer Basin, which may contain up to 10 km of Neoproterozoic to Paleozoic sediments, is bounded by the Precambrian Gawler Craton to the southeast, the Musgrave Block to the north, and passes into...

13 sedimentary rock samples from Proterozoic through to Mesozoic formations intersected in 5 Officer Basin wells yielded apatite fission track analysis data (track length and density) used to interpret, via statistical modelling, the broad geothermal...

Following the allocation in 1992 of Aust $2 million to MESA for petroleum exploration as part of the SA Exploration Initiative, the Department undertook to conduct reconnaisance seismic surveys over selected, poorly known sedimentary basins. As part...

Preliminary analysis of 6 core samples from 1237-1266 metres depth in Giles 1 has revealed poor to fair organic richness, low concentrations of extractable organic matter and low hydrocarbon yields. Rock-Eval pyrolysis has confirmed the presence of...

Burial history analysis of the structurally complex eastern Officer Basin region was performed using data from petroleum, trona exploration and stratigraphic wells, seismic upholes, coal drillholes and selected seismic sections, to construct isopachs...

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...

A new generation, first edition WINTINNA 1:250 000 scale geological map and explanatory notes have been published. These documents represent the conclusion of the Geological Survey of South Australia's geological mapping program undertaken in the...

The OOLDEA 1:250 000 map area, in the far west of SA, includes portions of the Maralinga Tjarutja Aboriginal Lands, Maralinga Prohibited Area, and Nullarbor Regional Reserve. It is traversed by the Trans-Australian Railway. There is no significant...

The WINTINNA 1:250 000 mapsheet area lies between latitudes 27° to 28° South and longitudes 133°30’ to 135°00’ East. This ~16 400 square km area includes the Marla and Cadney Park settlements, and is crossed by the Stuart Highway and Adelaide to...
