Survey was conducted over traverse which overlays SADME seismic line ED.

2 major circular aeromagnetic anomalies flanked by residual gravity anomalies were tested, but the gravity anomalies are not analogous to Olympic Dam. The magnetic anomalies occur within an inferred fault zone suggesting similar mode of origin.

Magnetic and gravity data were assessed to determine the potential for Roxby Downs type mineralisation. The Welbourn Hill magnetic anomaly is most likely due to an intrusion lying at a depth of about 1800 m. A residual gravity anomaly of about 6 mGal...

This report reviews the evolution of depositional environments for the Australian Permian sequence, particularly in regard to the formation of coal, and describes the interpreted nature of sedimentation in the Arckaringa Basin. The depositional...

To obtain a broad overview of the regional structural setting, Landsat image interpretation was undertaken covering 200 000 square km. 2 lineament sets dominate the regional structural trends. Set A is aligned NE - SW and NW - SE, and appears to...

TRONA EXPLORATION: Of the 9 rotary/diamond holes drilled, only the first, Meramangye 1, intersected a unit equivalent to the Observatory Hill Beds, which was the target horizon for trona. Drillholes Manya nos 2-6 and Marla 7 intersected Cambrian red...

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,...
