Analysis of a single wood sample from a silicified low energy, poorly sorted, sandy, fluvial horizon within an apparent palaeovalley on the Gawler Craton is identified as a member of the botanical family Podocarpaceae, with a possible affinity to the...

The Adelaide Geosyncline is a deeply subsident Neoproterozoic to Middle Cambrian basin complex in South Australia with a record of at least five major successive rift cycles. Each rift system has its own locus and orientation. Although the rift...

Metropolitan Adelaide is founded on a wide variety of soils that overlie sediments and rocks. Some of the soils and sediments react to seasonal and human-induced changes in water content with marked changes in volume. The black earths and...

The Curnamona Province is exposed in the Willyama, Mt Painter and Mt Babbage Inliers, but much is obscured by younger sedimentary cover. It comprises a late Palaeoproterozoic metasedimentary and metavolcanic succession (Willyama Supergroup) with some...

The groundwater model described in this report was used to quantify the changes in salt loads to the River Murray and induced discharge to the degraded river flats of proposed future management options for the Loxton Irrigation Area. The options...

The palynofloras from eight drill cuttings samples taken from the depth interval 107-181 m KB in SADME Wilkinson 1 are described and dated. The youngest palynofloras are correlated with the Upper Nothofagidites asperus Zone, and are dated as latest...

Palynological analyses of nine grab samples from the Lochiel coal test pit show two distinct floristic types, i.e. Haloragacidites spp. dominated and Nothofagidites spp. dominated palynofloras. This distinction is interpreted as indicating a change...

The United States Geological Survey software package MODFLOW was used to construct a three-layer predictive simulation model of the groundwater flow underlying Emu Springs, an area in the southern Mallee region of South Australia near Tintinara. The...

A combined groundwater and solute transport model (MODFLOW and MT3D) was constructed of the Loxton Irrigation Area to determine the future impacts on groundwater levels and salt loads to the river and floodplain for a range of local irrigation...

This 4-day field trip demonstrates :- Willyama Complex (basement) stratigraphy,- deformation and metamorphic style of the Olarian, Orogeny (including possible recumbent folds), - large blocks of granite and migmatite, up to 800 metres, long, within...

Areas of high mineral potential within Adelaidean basement lying beneath deep Recent and Tertiary Murray Basin cover, have been interpreted in the poorly known Sandleton 1:50 000 map area. The interpretation has outlined the magnetic fabric, variously...

The offshore extension of the Eden-Burnside Fault has been mapped from shallow-penetration seismic reflection profiles. Between Hallett Cove and Port Noarlunga, it parallels the coastline 2 km offshore. The fault separates a coastal platform of thin,...

Some of the first dates from the Simpson / Tirari Desert are presented. It is argued that Late Pleistocene episodes of dune development are widespread, and may be at least as important as the Holocene episodes in depositing dune sediments and shaping...

8 drill cuttings samples of cover sediments from the Millers Creek Homestead area were dated palynologically as an aid to regional diamond exploration for buried kimberlite intrusions. Despite poor preservation of most palynomorphs, it was possible to...

2 grab samples of carbonaceous sediments from an outcrop located 6 km south-southwest of Reg Dam were examined to determine whether they belong to the Jurassic Algebuckina Sandstone or the Permian Boorthanna Formation. An Early Permian (Late...

A lamprophyre province has been identified in the Truro area comprising numerous dykes and at least one diatreme. The regional extent of the province has not been determined. The lamprophyre dykes, of the calc-alkaline suite and classed as minette,...

Significant anthropogenic land subsidence within the Port Adelaide estuary of up to 0.7 metres is inferred from the Holocene stratigraphy and associated radiocarbon dates on materials that act as palaeo-sea level indicators. Principal contributing...

The aim was to derive a new method for the evaluation of porosity and water saturation for Pretty Hill Sandstone reservoirs, Otway Basin. Over 350 core plugs were measured for ambient and overburden porosity and permeability, and absolute grain...

Stable isotopes (deuterium, carbon-13 and oxygen-18) and radiocarbon (carbon-14) have been used in conjunction with chemical data to evaluate recharge mechanisms, groundwater residence time and palaeohydrology within the confined Dilwyn Formation sand...
