Continuing geological, geochemical, petrographic and ground magnetic work was done by AAP along 26 sampling profiles to try to unravel possible stratigraphic and tectonic controls on known base metal mineralisation at the Royal Keyneton and Hope mine...

Reconnaissance sampling of the Cambrian Heatherdale Shale and its equivalents further south showed only minor concentrations of phosphate.

21 specimens of volcanics and felsic gneisses are heterogeneous in both original lithology and the extent of metamorphic and metasomatic alteration. Strong granitic metasomatism may indicate concealed granitoid plutons. Continuation of andesitic...

The Red Creek section is proposed as a reference section for the Heatherdale Shale, Truro Volcanics, Carrickalinga Head Formation and Backstairs Passage Formation for the Karinya Syncline area of the Kanmantoo Trough. To date, 934 metres have been...

An integrated scientific research program addressing structural, sedimentological and metallogenic aspects of basin evolution has been conducted in the Kanmantoo Trough for the past three years. Joint collaboration in this program involved MESA, the...

A trachyandesite from the Gawler Range Volcanics at Buckleboo and an alkali basalt from the main quarry at Mount Schank are suitable for Departmental geochemical standards. A sample from an outcrop of Heatherdale Shale at Carrickalinga Head is a...

The Cambro-Ordovician basement underlying Murray Basin sediments in the Cooke Plains and Coomandook areas was sampled by a reverse circulation drilling programme as part of the South Australian Exploration Initiative. Greenschist to low amphibolite...

During September 1999, a single diamond drillhole, fully cored to 599 m total depth, was put down within the Karinya Syncline 12 km south-east of Eudunda, targeting possible economic buried syngenetic - epigenetic Pb-Zn-Ag mineralisation hosted in...

Possible epithermal/hydrothermal and shear-related vein style gold, and Proterozoic and Cambrian metasedimentary-hosted industrial minerals, were the targets of reconnaissance exploration over a licence taken up in the Barossa region. 1:2000 scale...

Geothermal modelling has been carried out at 9 locations in or around the Stansbury Basin, at the request of Canyon Australia, with the aim of examining the basin's thermal history and deducing a likely time of petroleum generation. A total of 20...

The Heatherdale Shale and the stratigraphically younger Karinya Shale are transgressive units within the Lower Cambrian of the Karinya Syncline. Black muds of the Heatherdale Shale were deposited in an outer ramp setting of the Stansbury Basin under...

Field examination of common asphaltite occurrences on Kangaroo Island beaches has concluded that they are relatively recent strandings of unknown origin and age. Their presumed sea floor mode of transport indicates a likely nearby source within the...

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...

Report summarises the stratigraphic, sedimentological and organic geochemical data so far assembled for the Heatherdale Shale where it outcrops on the Gulf St Vincent coastline south of Adelaide, with the aim of: - establishing the location and...

A detailed study of the stratigraphy, sedimentology and thermal history of the Heatherdale Shale, the youngest unit of the Early-Mid Cambrian Normanville Group (Fleurieu Peninsula, South Australia), was undertaken to elucidate its petroleum source...

As part of a regional search for possible economic stratabound Kanmantoo / Mount Torrens type base metal mineralisation, CRA undertook follow-up geochemical sampling traverses in areas surrounding Eudunda, where the SA Department of Mines and Energy...

Large sedimentary phosphorate deposits are unlikely to be found in the Cambrian on Fleurieu Peninsula or the southern part of Yorke Peninsula. Further exploration of the phosphatic Brighton Limestone and Saddleworth Formation type of facies should be...

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...

A gossanous bedrock outcrop present within Early Cambrian sediments of the central Fleurieu Peninsula, and situated 16 km north-east of Mount Compass township, was investigated as a possible Mississippi Valley - type (MVT) base metals target....
