This report presents the results of SHRIMP U-Pb zircon geochronology from the southern Gawler Craton that has been acquired with the view to improving our understanding of some key stratigraphic units of this region. Eight samples taken from outcrops...

New electron microprobe monazite geochronological constraints on the timing of Proterozoic granulite facies metamorphism from the western Gawler Craton are presented. Monazite grain geochronological data obtained from samples of basement rocks...

During the period June 2008 to October 2011, the Geological Survey of South Australia was one of the sponsors for a Mineral and Energy Research Institute of Western Australia research project conducted using the zircon U-Th-Pb-He double dating...

As part of the current mapping programme aiming to produce a second edition of the PORT AUGUSTA 1:250k geological map sheet, 8 rock samples from outcrops located on this map sheet area and on the adjoining WHYALLA 1:250k map sheet area were...

Includes abstracts with the following titles: 1) Deep crustal architecture and Moho depth offset beneath the Musgrave Province defined by a high resolution gravity survey (Alan Aitken - presenter, Peter Betts and Daniel Gray) 2) Palaeoproterozoic...

Re-sampling of fine-grained sedimentary drillcore from near the depth interval 266.1 to 281.9 metres KB in Murnaroo 1, for Rb/Sr age dating, has resulted in an better isochron of 745 +/- 87 Ma, i.e. Proterozoic, with a significantly reduced uncertainty.

The object of this study was to produce a single, robust groundwater dataset for South Australia that could be combined with other datasets sourced from elsewhere across Australia. Utilising historical data qualified by minimal metadata is not ideal...

This report presents SHRIMP U-Pb zircon geochronology results for 21 samples from the Musgrave Province, South Australia, acquired over the period 2007-2012 as part of the Tieyon 1:100 000 mapsheet (5645) mapping program. Some of the work (done on all...

INTRODUCTION TO THE GUIDE Northern Yorke Peninsula (NYP) is within the southern portion of the Olympic Domain of the eastern Gawler Craton, which is arguably the world’s most fertile IOCG belt. That such a belt existed was only realised when Western...

This paper provides a formal definition of the Cultana Subsuite, outlining the igneous petrology of the intrusion, its geochemical characteristics, and the nature of hydrothermal alteration and brecciation affecting the rocks. The Cultana Subsuite is...

The Honeymoon and East Kalkaroo sedimentary uranium deposits, located approximately 400 km north-east of Adelaide and 75 km north-west of Broken Hill, are natural concentrations of uranium minerals occurring in the Tertiary age Yarramba Palaeochannel,...

Groundwater flows mainly through two major aquifer systems: a regionally unconfined aquifer, and an underlying confined aquifer. The two aquifers are separated by a low permeability confining bed (or aquitard). Determining the degree of hydraulic...

Two samples of folded Adelaidean equivalent age sediments which form the basement to the (?) Cambro-Ordovician Officer Basin, obtained from rock outcrops in the Chambers Bluff region of the north-eastern Officer Basin, were analysed geochronologically...

6 out of 10 selected samples of drill core taken from the depth interval 157.13 to 177.88 metres KB in drillhole Byilkaoora 1 underwent rubidium - strontium geochronology to determine their age of deposition. The analytical results proved ambiguous,...

An airborne magnetic/radiometric survey to infill recent SAEI regional survey coverage was carried out within the G2 structural corridor, south-east of Port Pirie. Six bullseye magnetic highs, consistent with kimberlite emplacement, and one having...

Groundwater sampling, aeromagnetic interpretation, shallow auger sampling and isotope studies were carried out over an area 30 km northeast of Elliston. Heavy mineral concentrates from composite auger samples contained zircon, galena and sphalerite,...

10 samples of fine-grained sediment taken from between 379.1 and 385.0 metres depth KB in Wilkinson 1 were examined to determine their suitability for Rb-Sr geochronology.

Possible Century or Neves-Corvo style stratabound and barite - associated, thinly bedded lead-zinc-copper sulphide/sulphate mineralisation existing in Late Precambrian to Lower Palaeozoic marine sediments of the Adelaide Geosyncline, was the target of...

An aeromagnetic / radiometric survey was carried out within the G2 structural corridor, south-east of Port Pirie, as part of a search for possible Moonta, Olympic Dam or Ernest Henry type gold - copper mineralisation, and for any diamond-bearing...
