TARGET: Uranium in Tertiary sediments in the vicinity of Lakeside Bore. EXPLORATION: 2 vertical rotary mud holes for a total of 1044 feet were drilled and geophysically logged during September 1972. RESULTS: The radiometric logs did not show...

Following a review of existing regional geophysical and geological data for the north-western Stuart Shelf, grid-based gravity and ground magnetic surveys were run to further outline two broad gravity highs associated with discrete magnetic anomalies,...

Four boreholes completed in Lake Eyre North and one in Lake Eyre South have provided further information on lake sediments and the stratigraphy of the Lake Eyre Basin. Modern lake sediments constitute a thickness of less than 15 feet in the deflated...

The MARREE mapsheet area lies in arid country about 400 miles north of Adelaide, South Australia. It includes the town of Marree, on the Alice Springs railway line, and part of the Birdsville and Strzelecki tracks. The area is covered mainly by flat...

Two sandstone sequences, one un-named and one equivalent to the Watchie Sandstone, have been recognized on CURDIMURKA. These sandstone sequences occur beneath the Etadunna Formation. Both are believed to be equivalent to the Eyre Formation. The...

10 fully cored shallow holes (total 543.2 m) were rotary mud drilled at four localities by the Australian Commonwealth Bureau of Mineral Resources (BMR) to elucidate the cover stratigraphy, particularly the upper age limit of the Etadunna Formation,...

The foraminifer, unlike any previously recorded from Etadunna Formation, is identified as Buliminoides sp. cf.B. chattonensis' (Finlay), and is compared with 3 widely separated Late Oligocene forms (New Zealand, Northern Adelaide Plains, Rhine...

Includes surface and subsurface stratigraphic data, and a geological map at 1:500 000 scale. 18 bores were re-logged.

18 drill cuttings samples taken from 4 mineral exploration holes were examined for making palynological age determinations. 11 samples were variously identified as being sediments of Middle Miocene freshwater or Early Cretaceous marine facies.

A system of parallel arcuate ridges dominates the topography of the Billa Kalina area; facies relationships indicate that they are silicified strandlines of a Miocene lake which have been etched out by later erosion. Clays and dolomites of the Miocene...

Brief summary progress report.

Two major palaeodrainage systems of Tertiary age, with watersheds of up to 35 000 square km and channel lengths of 200-250 km, have been recognised and delineated using LANDSAT imagery, during 1:250 000 scale geological mapping in western South...

The widespread extent of silcretes in SA is demonstrated through stratigraphic relationships with palynologically dated sequences, and erosion of silcretes. The late Tertiary silcrete dominates the duricrusted landscape. Silica type varies according...

Land snails - Bothriembryon praecursor andMeracomelon lloydi' from the type section of Etadunna Formation at Lake Palankarinna and freshwater species of Syrioplanorbis,Physastra' and `Rivisessor' from dolomitic limestones near Billa Kalina and...

Plant macrofossils from silicified Cainozoic fluvial sediments on CURDIMURKA occur in 2 discrete suites. One suite has been found only in outcrops of silicified Eyre Formation in the Poole Creek Palaeochannel. This suite and the macroflora of the...

Specimens illustrate deposition by intermittent drainage in a possibly migratory channel. Well-sorted quartz grains from a mature sediment were deposited with a carbonate mud as matrix in the channel and silty mud precipitated in backwaters....

In a search for possible economic roll-front, blanket style uranium deposits within Tertiary sediments in part of the eastern Frome Embayment, the licensee undertook 1:75,000 scale geological mapping and exploratory auger drilling of the Quaternary...
