Report presents the basic data and geochronological age interpretations for 89 K-Ar and 64 Rb-Sr isotopic analyses, made on metamorphic, granitic and volcanic rock samples derived from parts of the Musgrave Block visited by SADME geologists between...

The Mann and Tomkinson Ras. are situated in the extreme north west of the state and approximately 400 miles WNW of Oodnadatta. The area includes portion of the native reserve. A rapid geological survey was carried out in late August 1953 when the...

The Alberga 4-mile military sheet, situated in the far northeast of the State is bounded by 132° to 133°. E longitude and 26° to 27° S latitude. It embodies the following 1 mile sheets: Giles, Eranbella, Indulkana, Kenmore, Alourra, Moorilyanna,...

Evidence is advanced for the existence of a major orogeny in Late Archaean time, in which an east to west geanticlinal belt was upthrust and the Giles Complex of basic rocks emplaced beneath a volcanic cover on the southern flank of the geanticline.

Almost six weeks were spent with the Far North-West party at Granite Downs Station in conducting magnetic and gravity traverses. Work was curtailed before sufficient results could be obtained for an accurate picture of subsurface structure. Gravity...

ABMINGA lies on the eastern edge of the Musgrave Block, which consists of Early to Middle Proterozoic gneisses and granites, intruded by dolerite dykes. A small area of folded and faulted Adelaidean and Cambrian sediments lies in the SW corner....

In the search for groundwater over 90 km, 11 potential sites were selected on geological grounds. The Transient EM (TEM) surveys assessed ground resistivity, initially over 2 pre-drilled test areas. Of the other 9 areas, 6 showed favourable...

Compilation of available data shows that of 45 outstations, only 12 have water supplies for which both nitrates and fluorides meet WHO standards, 27 have unacceptable fluoride and or nitrate levels, and 8 have not been tested for both nitrate and...

This is a compilation of available geophysical data and review of interpretations of the Everard Thrust. It includes regional distribution maps of the Cambrian, Ordovician, Devonian and Permian rocks. Geophysical and geological interpretations pre...

Report criticises the methods, presentation and conclusions of a non-professional chrysoprase mining feasibility study prepared for the Commonwealth Government Opposition by parliamentary advisor J.P. West.

38 wells have been drilled testing 3 geological environments. Results indicate : (1) Crystalline Precambrian rocks yield small supplies with salinity 15 000 to 20 000 mg/L. (2) Adelaidean slates and quartzites are capable of moderate yields, but...

Fregon, south of the Musgrave Ranges, is supplied with water of 1100 to 1 500 mg/L from a weathered crystalline rock aquifer. This report aims to document all water investigations and determine if water chemistry has changed with time. About 100...

11 of 13 wells, in fractured rock aquifers were tested. Most showed drawdowns linear with the square root of time, and consequently long term yields are generally much smaller than airlift yields. 6 were found to have long term yields greater than 0.5...

Drilling has located small but adequate supplies of groundwater in fractured crystalline basement. Nitrate contents are unacceptably high, about 100 mg/L. Previous drilling has shown that nitrates are ubiquitous in this area, and that further drilling...
