The Frome airborne electromagnetic survey, South Australia: implications for energy, minerals and regional geology

The Frome Airborne Electromagnetic (AEM) Survey was designed to deliver reliable precompetitive AEM data and scientific analysis to aid research into the potential of energy and mineral resources in the Lake Frome region of South Australia. The Survey was the third regional AEM survey conducted within the Onshore Energy Security Program (OESP) at Geoscience Australia (GA), following the Paterson and Pine Creek AEM surveys. The Survey was flown by Fugro Airborne Surveys (FAS) for Geoscience Australia between 22 May and 2 November 2010, using the TEMPESTTM time-domain electromagnetic (TEM) system. Survey lines were flown east-west at a nominal 100m above ground level, and spaced 2.5km or 5km apart. A total of 32 317 line km of new data were collected over an area of 95 450km2, approximately one tenth of the area of South Australia.
The survey area extends from the South Australia-New South Wales border at Cameron Corner across to the Marree and Leigh Creek areas, skirts the highland of the northern Flinders Ranges, and includes the entire Lake Frome area, the Olary Spur between the towns of Yunta and Cockburn and the northwestern Murray-Darling Basin.
The Lake Frome region contains a large number of sandstone-hosted uranium deposits with known resources of ~60 000 tonnes of U3O8, constituting ~45% of uranium resources of this type in Australia. The Survey was conducted with the aims of reducing exploration risk, stimulating exploration investment and enhancing prospectivity within the region primarily for uranium, but also for other commodities including copper, gold, silver, lead, zinc, iron ore, coal and groundwater. The Frome AEM Survey was designed to be a regional mapping program for imaging surface and subsurface geological features that may be associated with sandstone-hosted uranium systems.
Interpretations of the Frome AEM Survey data provide a regional overview of the under-cover geology of the entire survey area, as well as providing detailed along-line information to give users a greater understanding of previous detailed investigations within small areas. The data have mapped features of fertile sandstone-uranium systems and have highlighted many new areas of prospectivity for uranium and other commodities.

Seximembrate apparatus structure of the Late Cambrian coniform conodont Teridontus nakamurai from the Chatsworth Limestone, Georgina Basin, Queensland

The multielement structure of the Late Cambrian euconodont Teridontus nakamurai (Nogami, 1967) is shown to be a seximembrate apparatus consisting of Sa, Sc, Sb, Sd, Pb and Pa elements.  No M element has been identified and none is expected in this type of conodont. All elements are coniform with a hyaline base and albid tissue in the cusp extending from the apex of the basal cavity to near the cusp tip. The cusp tip is usually hyaline. The albid tissue is dense and the juncture of hyaline and albid tissues at the basal cavity apex is usually abrupt and planar, rather than tapered as found in most coniform element species. Albid tissue fills the entire diameter of the cusp, and there is no outer layer of hyaline tissue. The S elements have a relatively long base and are differentiated by their cross-sectional shape. The P elements have a short base and different cross-sectional shapes.  The surface of all elements is covered with a very fine striate ornament, but the elements lack other surface structures, such as keels, carinae, costae and grooves.

Georgina Basin South, NT/QLD, 1964 (P284), magnetic line data, AWAGS levelled

Total magnetic intensity (TMI) data measures variations in the intensity of the Earth's magnetic field caused by the contrasting content of rock-forming minerals in the Earth crust. Magnetic anomalies can be either positive (field stronger than normal) or negative (field weaker) depending on the susceptibility of the rock. The data are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.
 These line dataset from the Georgina Basin, NT/QLD, 1964 survey were acquired in 1964 by the NT, QLD Government, and consisted of 105340 line-kilometres of data at 3200m line spacing and 230m terrain clearance. To constrain long wavelengths in the data, an independent data set, the Australia-wide Airborne Geophysical Survey (AWAGS) airborne magnetic data, was used to control the base levels of the survey data. This survey data is essentially levelled to AWAGS.

The West Tasman Sea (Flinders Island) earthquake of 14 September 1946

The largest southeastern Australian earthquake this century occurred in the West Tasman Sea, 100 km east of Flinders Island, at 1948 UTC on 14 September 1946.  Its epicentre was at 39.97Â°S, 149.35Â°E and its Richter magnitude ML 6.0. It was felt strongly throughout Tasmania and Gippsland, Victoria, and caused minor damage in Launceston. The isoseismal map of the earthquake is consistent with lower strong ground motion attenuation in Tasmania than in mainland southeastern Australia, and the macroseismic effects suggest amplification of seismic shaking by Tertiary lake sediments in Hobart and Launceston.

Geological Cross-section of the Arafura Basin

The Arafura Basin contains a sequence of Palaeozoic rocks
lying north-east of Darwin, and which extends from onshore
Australia, to perhaps as far as the Irian Jaya mainland. There are
over 9 km of Palaeozoic rocks preserved along the southern bounding
fault of a major graben (the Arafura Graben) located in the
southern part of the basin. In the uplifted centre of the graben,
there is less than 3 km of the Palaeozoic section preserved. The
basin is underlain by a Middle to Late Proterozoic sequence which
thickens to the east, and is probably equivalent to the onshore
McArthur Basin. Overlying the Arafura Basin is the Mesozoic Money
Shoal Basin, which is approximately 1 km thick over the central
parts of the graben, thickening rapidly to the west and thinning
to the east and north.
The structural cross-section that has been drawn is
located entirely offshore. It has been compiled using modern
seismic and well control. It runs from south-east of Tasman 1 in
a general north and north-east direction tying with Torres 1 and
Arafura 1. It passes through the central and north-eastern parts
of the graben, and the north-eastern part of the basin. Two-way
time to depth conversions were based on the velocity surveys from
the wells within the graben, but were modified locally outside the
graben. The structural analysis presented is largely based on the
evidence found along the line of the section. A more complete
structural analysis would require a regional examination of the
entire seismic network. Information from the recently published
Petroleum Basin Study on the Arafura Basin (Northern Territory
Geological Survey) has been incorporated into this report, although
there are major differences between some of their findings and the
interpretations presented here.
To date the major risk in hydrocarbon exploration has
been finding adequate reservoir conditions and seal. Contradictory
interpretations are present between the maturation and structural
modelling of the graben. Untested plays include possible Permian
and Triassic sediments (up to 5 km thick) which exist along the
flanks of the graben and which will probably contain good source
potential and improved reservoir conditions. To the north outside
the graben, there are poorly explored areas where it is speculated
that there are thick Palaeozoic and Proterozoic sequences.
