Gawler Craton: New Releases

Maitland Special Explanatory Notes

 

The Maitland Special Explanatory Notes have been released and are available as digital download. This document follows the publication of the Maitland Special 1:250 000 Geological Map published in 2003. While the map is a second edition product, the accompanying notes have never been published previously and so constitute a valuable resource to explorationists and academics alike.

The map area covers the historic Moonta Wallaroo mineral field. The product will also appeal to the general public in light of the tourist appeal for the area Both products were authored by Wen-Long Zang of the Geological Survey Branch. The geological map covers the major part of South Australia’s Yorke Peninsula. The rocks in the map area comprise deformed Palaeoproterozoic and early Mesoproterozoic basement of the southeastern Gawler Craton, and undeformed Neoproterozoic to Quaternary sediments. More than 90% of the land surface of the map area is covered by Quaternary sand dunes, calcrete, aeolianite and soil.

Crustal Evolution of the Gawler Craton, South Australia

 

As part of a significant effort to improve the availability of geochronological data generated by PIRSA and its collaborative partners, PIRSA is pleased to announce the release of the Report Book - Crustal Evolution of the Gawler Craton, South Australia: Application of the TerraneChronŽ technique to detrital zircon from modern stream sediments. This product is a result of integrated research between GEMOC and PIRSA (co-authored by Anthony Reid of the Geological Survey Branch).

This report presents the results of a TerranechronŽ study of detrital zircons from modern stream sediments of the Gawler Craton. The TerranechronŽ approach involves obtaining U-Pb ages, Hf isotope composition and trace element data from single zircon grains, which provide an insight into the age, source rock evolution and source rock type on the analysed zircons.

Guide to the sedimentary cover of the central Gawler Craton, South Australia

(with special emphasis on the Harris Greenstone Belt region)

 

The Guide to the sedimentary cover of the Central Gawler Craton, South Australia (with special emphasis on the Harris Greenstone Belt region) is a report book prepared by Geological Survey Branch geologists Paul Rogers (now retired) and Wenlong Zang.

This report book will serve as a valuable resource for mineral exploration through and within the cover of the central Gawler Craton, and many of the presented concepts can be applied to the other areas of this geological province.

Yardea Explanatory Notes

 

Exploration activity is reaching record levels in the Gawler Craton stimulated most recently by the SA Government's commitment to exploration through the PACE Initiative.

One area attracting a great amount of interest is the southern margin of the Gawler Ranges. The area already hosts a number of mineral prospects including the Menninnie Dam base metal project and the Barnes, Weednanna and Baggy Green gold prospects.

The 1:250 000 YARDEA Geological Map was originally published in 1988 though at the time, no explanatory notes were released. Ex-PIRSA geologists, A. J. Parker and R. J. Flint (then of Geosurveys Australia Pty Ltd) were engaged to produce the accompanying YARDEA Explanatory Notes. Their initial version was only ever available as an internal draft and received extensive modification and revision by PIRSA geologists.

The Mineral Resources Group can announce the 1:250 000 YARDEA Explanatory Notes are now complete and available for the first time in digital format.
