This EPP 26 surrender report has been furnished to the SA offshore Designated Authority as a result of the application made on 21/8/96 by BHP Petroleum for permission for the joint venture to surrender the permit, before committing to unwanted...

Analysis of Pliocene sedimentation along the Padthaway Ridge has identified a major shoreline feature in the Marmon Jabuk Range, with associated, but younger, shorelines developed in the Padthaway area. Traversing and sampling has established the...

This report is intended to be a convenient single reference to the Cattlegrid ore deposit geology. It represents an updated summary of a large amount of data, gleaned largely from internal company reports. The subject matter relates mainly to the...

AIM: The 1993 Troubridge Shoals Seismic Survey programme, of shallow water/shelf transition zone coverage on the southwestern and western sides of Gulf St Vincent, was designed to tie the extensive offshore seismic data of recent vintage to the...

TARGET: Now buried heavy mineral sands accumulations that may have formed within the Tertiary Parilla Sand as palaeo-beach placer deposits. EXPLORATION: Appraisal of SADME-held water bore data, photogeological studies, geomorphic mapping,...

TARGET: Possible economic heavy mineral sand accumulations in Pliocene raised beach strandlines developed along the south-western margin of the Murray Basin. EXPLORATION: Acquisition of an airborne magnetic and radiometric survey during November...

TARGET: Possible economic heavy mineral sands accumulations that may have formed in the Pliocene palaeocoastal dune and beach ridge sand sequence of the Marmon Jabuk Range, within an area extending south-eastwards from Tailem Bend for ~80 km.....

The heavy mineral potential of Tertiary sediments in the Chundie Swamps was investigated with 2 drill traverses (43 RC open vertical holes totalling 863 m) and reconnaissance soil mineralogical sampling. Heavy mineral contents were very low.

TARGET: In an untested area immediately west of Leigh Creek, extending as far as the eastern side of Lake Torrens, ETSA was aiming to find buried deposits of Late Palaeozoic or Mesozoic coal of a rank at least equal to that of Leigh Creek coal (and...

2 main types of copper deposit are recognized. 1 of these is of low grade, near the base of the laminite sequences in the Woocalla Dolomite, probably of syngenetic origin, and is believed to be the oldest and primary kind of deposit. (Gully, MG 14...

TARGET: Sulphides at Whyalla Sandstone - Pandurra Formation contact (Cattlegrid type), in Woocalla Dolomite (Sweet Nell type) and in black shale. EXPLORATION: Geological mapping at 1:30 000 scale, reconnaissance rock chip sampling, subsurface soil...

14 cored holes have intersected copper mineralization in shaley facies of the Woocalla Dolomite, and extending up into dark claystone at the base of the Whyalla Sandstone. The mineralised rocks occupy a shallow depression in the post-Pandurra erosion...

Opening up of the Cattlegrid pit has greatly elucidated the geology of the Whyalla Sandstone and the ore bearing zone of the Pandurra Formation and with the discovery of the MG 14 basic dyke and overlying mineralization, a much more direct association...

The Purni, Peera Peera and Poolowanna Formations were evaluated in terms of depositional and structural basin analysis using the model of Genetic Increments of strata (GIS). Eight reservoir intervals have been identified and the pertinent reservoir...

Initial study of the regional geology concluded that the structural deformation (large anticlinal synclinal) observed at the surface could be associated with the deformation of the Palaeozoic underneath the Mesozoic cover. 1:250000 structure contour...

The area is 1 of prolonged, active and deep sedimentation, and has probably been dominantly marine. Dark coloured shales, marls and limestones offer promising source rock conditions, and there are adequate reservoir sands and older dolomitised...

Structural interpretation of the pre-Adelaidean basement from aeromagnetic and gravity data defines uplifted basement blocks and basement fractures which were active as normal faults during deposition of Adelaidean sediments, controlling the...

Ongoing appraisal work conducted by CSR at the company's newly discovered Cattlegrid copper deposit that lies at the top of the Pandurra Formation has included infill rotary percussion and diamond drilling (13 holes for 554 m, including 166 m cored),...

There is no abstract created for this record

Summary is given of available data and appraisal of leads. The primary interest was in the basal portion of the Jurassic-Cretaceous Eromanga Basin. Secondary interest was in the Permian Pedirka Basin sequence.
