  • The aim of this project is to equip ANUGA with a storm surge capability in partnership with the Department of Planning Western Australia (DoP), take steps to validate the methodology and provide a case study to DoP in the form of a storm surge scenario for Bunbury. The developed capability will provide a mechanism whereby DoP can investigate mitigation options for a range of hydrodynamic hazards.

  • This report summarises the result of a study into seawater intrusion into coastal aquifers in the Northern territory coastal plain using AEM data, down hole geophysics, and bore hole geology carried out by Geoscience Australia on behalf of the National Water Commission and in partnership with NRETAS. The study showed that ground-validated AEM is able to map areas of saline aquifers in the area and differentiate them from bedrock conductors.

  • This report documents the findings of the Ord Valley Airborne Electromagnetics (AEM) Interpretation Project. The project was co-funded by the Australian and Western Australian Governments to provide information in relation to salinity and groundwater management in the Ord Valley, Western Australia. The project involved the acquisition of airborne electromagnetic (AEM) and Light Ranging and Detection (LiDAR) surveys, and complementary drilling, borehole geophysics, laboratory analysis and interpretation services. The project was undertaken under the auspices of the National Action Plan for Salinity and Water Quality, and managed by Ord Irrigation Cooperative (OIC) for the WA Rangelands NRM Group.

  • This work was prepared on a request to provide field infonnation on the Williams and Naraku Batholiths, which I visited in a series of short field trips in 1978, 1984, 1985, 1986 and 1988. I have only included data on the post D2 phases. I have included very little information on the Naraku Batholith, primarily because I have not done all that much work on it since my initial sampling trip in 1978. Five traverses are documented which focus in particular on the altered phases of the Williams Batholith and some albitite intrusions in the Naraku Batholith. My last trip to this area was in 1988, and since then, as there has been a considerable amount of exploration work done in the area, the access information may not be all that reliable. As far as is possible, I have recorded access as it was in my last visit, and I take no responsibility for accuracy, as I have not had the luxury of checking its current status. The five traverses documented are as follows: Traverse 1-Wimberu Granite Traverse 2 - Northern Squirrel Hills and southern Mount Angelay Granite Traverse 3 - Hampden Mines to northern Mount Angelay Granite and Cloncurry Traverse 4 - Tank Hole Bore and Glen Eva Homestead area Traverse 5 - The southwestern plutons of the Williams Batholith In the accompanying documentation I have provided a preprint of an article on the Williams Batholith from the next issue of the BMR Research Newsletter. It provides an overview of the Williams granite system and in particular refers to the concept of convective fractionation. I suggest that this article, as well as the article on "Granites: their tectonic and met allogenic applications" are mandatory reading before setting foot on any of the localities described in this report. I have also included a copy of the BMR regional radiometrics, as it is invaluable in determining the location of the fractionated phases. It is a hand coloured copy of the original diagram which appeared in the Bulletin on the Duchess-Urandangi Region. Finally, for anyone attempting to follow though on the traverses described in this area, remember that the Williams and Naraku Batholiths are the most interesting and spectacular batholiths that I have ever worked on. The diversity in primary magmatic phases and the overprinting alteration types is almost unique, and their association with Cu and Au mineralisation in the area is without question.

  • I was asked to examine 61 thin sections from the Horne of Bullion mine area east of Barrow Creek, Northern Territory. The thin sections were of rocks from an area believed to be prospective for Au ± Cu mineralisation of early Proterozoic age and possibly analogous to mineralisation styles similar to that found in other Proterozoic belts such as Cloncurry, Tennant Creek and the Granites/Tanami. This report is divided into 3 sections. Section 1 comprises a synthesis of the thin sections examined, Section 2 contains a discussion of the regional factors, whilst Section 3 discusses some implications for mineralisation. Appendix 1 contains brief petrographic descriptions of the thin sections supplied. In preparing this report, I have consulted with Dr Gladys Warren (because of her experience with granitic and metamorphic rocks of the Amnta Region, and her experience in the Barrow Creek area) and Dr Dean Hoatson (because of his experience with Precambrian layered intrusions including the Munni Munni Complex of the Pilbara Block and various Palaeoproterozoic mafic intrusions of the Halls Creek Inlier). However, all interpretations presented in this report are my own.

  • At the invitation of Newercrest Mines Limited I visited the Telfer Gold Mine from Tuesday July 12, returning on Thursday morning July 13th. Whilst at the site, I visited the open pit accompanied by Don Thompson, and with Don, Nick Langsford and Campbell Mackey visited sites of the Mount Crofton Granite at Mount Crofton, Minyari Granite at Minyari Hills, and the Wilkie Granite some 15 kms east of the Telfer mine. I also examined granite core in holes ORC 1-6. These notes describe my thoughts on the sites that I visited, and also give some recommendations for some potential future work. I have prepared these notes at the request of Nick Langsford and they contain information that is essentially off the top of my head. Please note that they are not meant to be comprehensive and that I have not had time to validate anything that is within them. I prepared these at the Newcrest Office in Perth on Thursday afternoon of July l3th and that I did some minor refinements to them back at AGSO on July 17th.

  • This report records the findings of a consultancy undertaken by the Minerals and Land Use Division of the Australian Geological Survey Organisation on behalf of North Flinders Mines. The two general objectives of this consultancy were (1) to form an opinion of the prospectivity of the Tanami region (particularly NFM tenements) for unconformity-associated Au-Pt-Pd±U mineralisation (2) to advise on exploration indicators of such mineralisation to be expected in the Tanami Region.
