Regional soil sampling has targeted the pyritic-carbonaceous Cambrian Karinya Shale and rock units immediately above and below it, along with lineament and structural features. Three prospect areas, Frankton, The Gap and Accommodation Hill, have been...

Within the northern Kanmantoo Trough at Frankton, The Gap and Accommodation Hill, newly defined aeromagnetic prospects were thought to have base and precious metal potential, and a possible igneous intrusive was the target at the Malabena prospect....

Results of earlier regional soil sampling conducted by SADME across the Karinya Shale, plus tectonic/structural considerations, had identified 3 prospect areas, Frankton, The Gap and Accommodation Hill, for follow-up mapping, soil sampling, and the...

A lamprophyre province has been identified in the Truro area comprising numerous dykes and at least one diatreme. The regional extent of the province has not been determined. The lamprophyre dykes, of the calc-alkaline suite and classed as minette,...

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...

Two structural regimes have been identified from Landsat Multi Spectral Scanner imagery covering Adelaide and the Mount Lofty Ranges: - a thrust terrain in the Adelaidean metasedimentary sequence; - the major Kanmantoo Shear Zone affecting the...

A geological study to assess the base metal potential of the Karinya Syncline led to a need for electrical geophysical surveys to assist in mapping geology and locating potential drilling targets. IP surveys were done on three sites, and TEM on one of...

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...

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...

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...

Exploration for possible economic stratiform/stratabound, volcanogenic-epigenetic lead-zinc mineralisation hosted within lower Kanmantoo Group metasediments of middle Cambrian age, over a small area located approximately 80 km north-east of Adelaide,...

An area centred ~15 km east of Eudunda, in the north-eastern Mount Lofty Ranges, has been explored initially for possible economic outcropping stratabound/replacement style phosphate mineralisation that may have formed within Adelaidean dolomitic...

Following earlier identification by PIRSA of mineralised gossans located at the stratigraphic contact between the Cambrian Karinya Shale and Backstairs Passage Formation, exploration comprising rock chip, soil and stream sediment geochemical sampling,...

Geological mapping plus regional rock chip geochemical sampling and soil C-horizon geochemical sampling conducted in the Australia Plains area, 12 km north-east of Eudunda, have identified a base metals anomalous zone at the base of the Karinya Shale.

The purpose of this interpretation is to provide an initial framework for the basement to the Murray Basin upon which to plan the Geological Survey of South Australia’s MinEx CRC National Drilling Initiative drilling project targeting the Delamerian...

This study has identified a model for syn-diagenetic base metal mineralisation in the Talisker Calc-siltstone. The sandstone - hosted stratiform mineralisation is dominantly lead-zinc in nature, and occurs within incised valley fills. The geological...

CRA's acquisition and interpretation of aeromagnetic and ground magnetic surveys, plus its gravel and stream sediment sampling, have successfully located a few kimberlites in the Truro area, 70 km north-east of Adelaide, where a large number of...
