An assessment of the mineral prospectivity of the Yellabinna Region in the far west of South Australia has been prepared to assist in discussing with the Department for Environment and Heritage the development of conservation strategies. The...

Possible diamondiferous kimberlite intrusions, and also economic base metals in the Cambrian bedrock strata, were the targets of exploration carried out in the Observatory Hill area, located approximately 250 km west of Coober Pedy. Initially, a 6200...

Stratigraphic drilling has been undertaken by PIRSA in the South Australian portion of the northern Murray Basin to investigate the stratigraphy and sedimentology of the Cainozoic sedimentary sequences, as well as the heavy mineral sand potential of...

18 drill cuttings samples obtained from three shallow PIRSA stratigraphic holes drilled in the Port Lincoln and Mount Hope regions of the southern Eyre Peninsula (LINC 10, LINC 13, LINC 47) have been palynologically analysed and dated. Palynomorphs...

Palynological analyses of eight drill cuttings samples from Burrungule 1 well, in the onshore part of the Gambier and Otway Basins, show distinctive microfloristic assemblages. The oldest samples are dated as Late Cretaceous (Maastrichtian), and...

Palynological analyses of 12 drill cuttings samples from the petroleum exploration well Morum 1, which was drilled in 1975 in the offshore part of the Gambier and Otway Basins, show distinctive palynofloral assemblages. The oldest samples are dated...

Palynological analysis and dating of samples from MPB 125 drillhole, St Vincent Basin, indicates the presence of late Middle Eocene sediments in the Lower Nothofagidites asperus Zone. Taxa from MPB 125 are correlated with palynofloras from One Tree...

Three drill cutting samples of carbonaceous sands were submitted for palynological analysis. The spore-pollen assemblages of drillholes NR 3 (from the depth interval 16-18 m) and NR 4 (16-18 m) are possibly of the latest Eocene Upper Nothofagidites...

Palynological analysis of one drill cuttings sample taken from the rotary precollar portion of BHP Minerals' Spencer Gulf diamond drillhole KGD01001 indicates the presence of Late Eocene - Early Oligocene sediments that are attributed to the upper...

The Proterozoic Curnamona Province extends across central eastern South Australia and into western New South Wales. Whilst most of the Province is obscured by younger sedimentary cover, regions of exposure are present in the northwest as the Mount...

A palynological analysis made of 25 cutting samples from three TEISA program stratigraphic drillholes (PIVA 1, PIVA 5 and PIVA 10) revealed distinctive microfloristic assemblages. Dinoflagellate cysts offer a reliable method for distinguishing the...

Palynological analyses of eight core samples taken from the Caroline 1 drillhole, onshore Gambier Basin, over the depth interval 748-827 m KB, indicate the presence of the Early Eocene, Lower Malvacipollis diversus Spore-Pollen Zone. A reconstruction...

Palynological analyses of eight cuttings and three sidewall core samples from the petroleum exploration drillhole Troas 1, in the SA offshore Otway Basin, show two distinctive microfloristic assemblages. The youngest samples are dated as Late Eocene,...

The middle Palaeoproterozoic rocks (2000-1800 Ma) on southern Yorke Peninsula are part of the Cleve Subdomain in the eastern Gawler Craton, which is separated from the younger Moonta Subdomain by the Warooka Fault Zone. The rocks contain a group of...

The 16th Australian Geological Convention (AGC) Musgrave Block Field Excursion, held during 6-16 July, came close to achieving unqualified success from the combined perspectives of technical geology, liaison between the traditional owners and the AGC...

A regional geological interpretation of newly-acquired magnetic data for the majority of the Musgrave Block (central Australia) has been compiled at 1:250 000 scale. This report outlines the methodology and results of interpretation. Highlights of...

The great majority of lower Palaeozoic rocks in the Stansbury, Arrowie and Warburton Basins are of Cambrian age, although a few Early Ordovician fossils have been reported from drillholes in the sub-surface Warburton Basin. The Cambrian is the only...

The Mingary 1:100 000 map area in the north-east of the state covers part of the Curnamona Province. Five suites of basic intrusives have been identified in the area. The most widespread is a series of amphibole-bearing sills which, having an...
