Oil shows in the Observatory Hill Beds in Byilkaoora 1 occur in a non-marine, alkaline playa lake sequence. Geochemical analysis suggests that they are immature and belong to 2 primary genetic families. The less altered oils are quite unlike...

The large, extinct, benthonic foraminifera Lepidocyclina, which has "tropical" affinities, has been found at two localities in the Nullarbor Limestone that outcrops on the eastern margin of the Eucla Basin. The species is apparently the usual,...

This field excursion was designed by the SADME Regional Geology Branch to enable participants to view some of the significant outcrops that provide evidence of sedimentation, stratigraphy, structure, metamorphism, phases of intrusion by igneous rocks,...

Shallow drilling (<30 metres) at 14 sites intersected a regressive coastal sequence of Quaternary bioclastic sediments deposited in coastal aeolian, littoral, lagoonal and evaporative-lagoonal environments. Major calcrete carapaces assist the...

Around Pavy Creek, the Parara Limestone disconformably overlies the Kulpara Formation and comprises dark blue-grey argillaceous limestone, with buff dolomite and skeletal packstone. Phosphate, pyrite, glauconite, and some fluorite occur in the...

Amino acid racemization data provide the basis for a predictive model for relative dating of late Quaternary coastal sequences. The extent of racemization on Last Interglacial fossils represents a linear function of latitude in southern Australia....

The proposed marina development site covers a considerable length of cliffs and wave-cut platform over which there is almost continuous rock exposure. It is located within the type section of the Marinoan Series which has been declared a Geological...

Shelly fragments amongst poorly sorted, dark grey subrounded quartz sands below Murray Group limestones were examined. It was believed that these might equate to marginal marine or paralic facies of Late Eocene Buccleuch Group. The earliest Tertiary...

Marginal marine strata of last interglacial age occur in a range of morphostratigraphic settings around the Australian coastline. Uranium-series ages for corals and molluscs are generally in accord with the accepted age for oxygen isotope substage 5e...

Recent advances in the understanding of the target Cambrian stratigraphy and its palaeogeographic setting, in combination with a realistic mineralization model, have established that the southern Arrowie Basin platform margin could be host to a...

A drill core sample of white bryozoal limestone taken from 156.9 m depth in hole Caringa 1 drilled near Karoonda in the Murray Basin was dated palaeontologically using the sediment's foraminiferal fauna. An early Late Eocene age was determined, which...

Two acritarch assemblages from the Early Ordovician Tremadocian and Arenigian stages are recognised from the subsurface Innamincka Formation (previously Innamincka Red Beds). The Tremadocian assemblage probably ranges back to the Late Cambrian, but...

Eighty-eight limestone samples from twenty profiles approximately 50 km east of Riyadh, Saudi Arabia are examined and named according to Dunhams 1962 classification of carbonate rocks. Ten main fossil groups are identified, namely: echinoderm...

The County Musgrave Proclaimed Wells Area on Eyre Peninsula, situated mainly near Elliston and extending eastwards towards Lock, contains a number of small groundwater lenses of potable quality which are surrounded by brackish to saline groundwater....

The sample from A68 E427190/53J N7068100 is Early Cretaceous (uppermost Barremian) in age and correlative with the Cadna-owie Formation. Open marine conditions are indicated, this being typical of the upper part of the formation in the southwestern...

Two groups of samples from Eyre Peninsula have been analysed. The Elliston samples are correlative with the Polda Formation, probably in the latest Middle Jurassic. The younger Middle Eocene E04-1 sample indicates the presence of Pidinga Formation,...

The Oak Valley Community requires a more convenient water supply. If potable groundwater cannot be found then a supply suitable for purification must be found. Current requirements are a supply of 1 L/s of water of salinity not greater than 40 000...

Water well 6628-13323 completed in Tertiary aquifer T1, and located on the Salisbury property of wool merchants and hide processors G.H. Michell and Sons (Australia) Pty Ltd, has an anomalously high groundwater salinity. Due to the increasing...

MESA were approached by the Kooyonga Golf Club in November 1995 for advice concerning the groundwater supply and quality from three old wells still in production. As indicated in correspondence dated 23/11/95, two of the wells show signs of saline...

This report is on the Otway Basin, South Australian sector. It covers the structural and tectonic history and the methodology of the seismic interpretation. Contour maps enclosed are time and depth structures of the Sherbrook Group, Eumeralla...
