A small suite of Cambrian rock samples was selected to evaluate the use of the methylphenanthrene index (MPI) and other aromatic hydrocarbon ratios as measures of thermal maturity in Early Palaeozoic sequences. Such very old rocks do not contain woody...

This section of the study was based on source rock analyses performed on 75 outcrop and shallow drill core samples from 25 localities, plus other new data derived from Cambrian sediments intersected in the deep petroleum exploration wells Moorowie 1,...

The Stansbury Basin is a relatively unexplored Cambrian sedimentary basin in South Australia. Good quality seismic data has defined a large untested prospect, the Investigator prospect, which has the potential to contain 200 to 300 mmbbl of oil, or...

Wertaloona Seismic Survey - AIM:The 1981 Wertaloona Seismic Survey programme was designed by the PELs 5 and 6 Arrowie Block partners to provide the first high quality, multifold seismic reflection data in the area of likely preserved thick Cambrian...

This study has shown that significant dolomite formation has occurred during early diagenetic stages in the Early Cambrian carbonate sequence of Yorke Peninsula. Relict depositional textures indicate that the sequence consists of tidal flat...

This report critically reassesses the biomarker geochemistry of the crude oil show encountered in the Wilkatana 1 well, using new analytical data, then compares its molecular composition with that of other Australian Cambrian oils, and discusses the...

AFTA palaeotemperature analyses of 7 selected Early Cambrian outcrop samples taken from potential hydrocarbon source beds occurring within PELs 53 and 59, were conducted by a Melbourne University consultant for Canyon Australia. The data and...

A programme of reconnaissance and infill geochemical stream sediment sampling, conducted over an area extending to the north-east and south-east of Hawker, examined the base metal potential of the Lower Cambrian limestone sequence overlying the Pound...

One diamond and seven rotary/percussion drillholes tested Cambrian rocks for base metals. Six water bores were logged geophysically. IP/resistivity and gravity surveys were undertaken.

Reconnaissance geochemical sampling of the eastern PARACHILNA mapsheet area for sediment-hosted base metal deposits has succeeded in locating several well-defined areas of interest, although approximately two-thirds of the SML area appears to be...

Following the previous conduct of separate reconnaissance and detailed stream sediment sampling programmes, two zinc-anomalous areas were defined. One of these, located in the nose of the Sliding Rock Syncline, was interpreted as arising from iron...

Exploration for possible Beltana - type diapir related hydrothermal base metal mineralisation undertaken in the Angepena area has consisted of regional stream sediment geochemical sampling (1498 samples of minus 20 to plus 80 microns mesh size) and...

This gravity survey portion laid out 2870 stations on the Lake Frome Plains, east and north-east of Reaphook Hill, to confirm and determine the extent of a postulated deep structural trough lying adjacent to the eastern flank of the northern Flinders...

In a search for possible economic Mississippi Valley - type base metal mineralisation within an area located 30 km north-east of Maitland, 941 auger holes for 6839.2 m total penetration were drilled at 100 to 200 m spacings along roadsides to test the...

During the period January 1946-December 1985 under review, the following petroleum exploration work was carried out over the Arrowie Block: 6 gravity, 2 aeromagnetic and 10 seismic surveys (total seismic coverage 2781 line km), plus 4 wells, all dry....

Yorke Peninsula lies between Spencer Gulf and Gulf St. Vincent. As its discoverer Matthew Flinders-wrote: "it is singular in its form, bearing some resemblance to a very ill-shaped leg and foot". This Bulletin deals with an area having an arbitrary...
