Thirty-two shallow auger holes up to 2.76 m deep were drilled into the floor of Lake Cadibarrawirracanna, situated 70 km west of William Creek, in a search for possible potash-rich brines trapped by the lake sediments. The lacustrine sediments were...

10 secns. 7 holes, TD 3516 ft.

The south-eastern Lake Frome Embayment in the vicinity of Quinyambie Station was explored for Upper and Lower Tertiary 'blanket' or 'roll front' type sedimentary uranium, via the drilling of 75 open vertical rotary mud holes with a total penetration...

153 rotary mud open holes (total 19,689 m) and 11 cored holes (total 1384 m) have been drilled during the reporting period to evaluate the Goulds Dam uranium deposit and to further explore the region to its north and south for sedimentary uranium...

Detailed base and precious metals exploration undertaken by Utah Development Company in the area of the Worumba Anticline has targeted possible stratiform Zambian Copperbelt - type deposits. Exploratory work has included 72 geochemical vertical...

The following Tertiary units were identified : Kongorong Fm, Narrawaturk Fm, Buccleuch Fm, Ettrick Fm, Mannum Fm, Kalibar Limestone, Parilla Sand and North West Bend Fm. All of these units are separated by unconformities. Erosional surfaces,...

WMC's Stuart Shelf exploration activities from 1975 to 1985 have sought mainly Olympic Dam style mineralisation (copper - uranium - precious metals in haematitic breccia host rocks), with lesser emphasis directed at: possible distal analogues of the...

Report presents results of the first regional hydrogeological survey of the Lower South-East area of South Australia, aimed at providing guidelines for optimising groundwater prospecting, use and protection during the period of strong urban,...

Good quality water with a salinity of below 500 grains per gallon is required for the washing of gypsum, a minimum supply of 1,500 gallons per hour being needed. In the Salt Lake District supplies of probably not more than 100 to 200 gallons per hour...

Carbonaceous sediments from tin leads in north-eastern Tasmania have yielded well-preserved and diverse pollen and spore assemblages from the deepest of three stratigraphic units sampled. On the basis of the microfloral assemblages, two...

The sediments are dolomitic and clay rich mudstones and siltstones with intraformational mud conglomerates and rare cherts. The effects of flood and drought are reflected in lithological changes related to fluctuations in the physical and chemical...

Geological interpretation from drilling and seismic information, on an Early Palaeozoic sedimentary basin containing Early Cambrian to possibly Devonian age rocks. Middle to latest Late Cambrian sediments (Kalladeina Formation) and probable Cambrian...

Palaeosol and organic rich horizons in exposed Bessette Sediments were investigated to determine the nature of Middle Wisconsin climate. Palaeoclimatic implications of palynomorph assemblages are that conditions at 42 000 years ago were at least 30C...

Surficial sediments are predominantly bioclastic, cool-temperate carbonates. Benthic foraminifera Elphidium crispum', a shallow water species, and 'E. macelliforme, favouring deeper water, provide useful numerical ratio which correlates with water...

The Benagerie Ridge is a basement high which has been actively shedding detritus since Adelaidean times. It includes porphyry, with thin cover of Adelaidean rocks, flanked by Cambrian and possible Adelaidean sediments. The Cainozoic blankets the...

The application of amino acid racemization reactions is explored for regional chronostratigraphic correlation of Last Interglacial marginal marine sediments. The extent of racemization evident for a range of amino acids in several molluscan species...

Modern pollen from extant vegetation was studied to aid in interpreting palaeoenvironments from fossil pollen assemblages. They record evidence of vegetation and climate during the penultimate or last interglacial.
