GSNSW Exploration NSW Area O NW Eromanga thorium grid geodetic

The radiometric, or gamma-ray spectrometric method, measures the natural variations in the gamma-rays detected near the Earth's surface as the result of the natural radioactive decay of potassium (K), uranium (U) and thorium (Th). The data collected 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.
This radiometric thorium grid has a cell size of 0.00077 degrees (approximately 80m) and shows thorium element concentration of the NSW DMR, Discovery 2000, AREA O, NW EROMANGA, NSW 2000 in units of parts per million (or ppm). The data used to produce this grid was acquired in 2000 by the NSW Government, and consisted of 54898 line-kilometres of data at a line spacing between 200m and 400m, and 60m terrain clearance.

Devonian and Carboniferous conodonts from the Bonaparte Gulf Basin, northern Australia, and their use in international correlation

The Bonaparte Gulf Basin is situated in northwestern Australia, partly in the Northern Territory and partly in Western Australia. It contains Palaeozoic rocks covering about 8,000 square miles of land around the Joseph Bonaparte Gulf (Fig. 1); the larger part of the Basin lies beneath the Timor Sea. A preliminary investigation of the geology of the Bonaparte Gulf Basin was published by Traves (1955). Previous published accounts of the geology include Matheson, Teichert (1948), Noakes et a1. (1952), McWhae et a1. (1958), and Thomas (1962). Noakes et a1. concisely reviewed previous geological investigations and Thomas summarized the previous work on the Carboniferous sediments of the basin. Conodonts are represented in the Upper Devonian and Lower Carboniferous faunas of the Bonaparte Gulf Basin by 159 species referable to 35 genera, of which 1 genus, Rhodalepis, 17 species, and 5 subspecies are new.

GSNSW Exploration NSW Area C Bourke magnetic rtp grid geodetic

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.
This magnetic grid has a cell size of 0.00063 degrees (approximately 65m).The data are in nanoTesla (or nT). The data used to produce this grid was acquired in 1995 by the NSW Government, and consisted of 93000 line-kilometres of data at 250m line spacing and 60m terrain clearance. The data has had a variable reduction to the pole applied to centre the magnetic anomaly over the magnetised body. The VRTP processing followed a differential reduction to pole calculation up to 5th order polynomial. Magnetic inclination and declination were derived from the IGRF-11 geomagnetic reference model using a data representative date and elevation representative of the survey.

AUSGeoid98 v.1.0 data files: Mount Young (sd53-15)

AUSGeoid98 data files contain a 2 minute grid of AUSGeoid98 data covering the Australian region, which you can use to interpolate geoid-ellipsoid separations for the positions required.You can use your own interpolation software, or you can use Geoscience Australia's Windows Interpolation software (Winter). The data files are text files in a standard format that cover the same area as standard topographic map areas. Files covering both 1:250,000 (approximately 100 x 150 km) and 1:1,000,000 (approximately 400 x 600 km) map areas are available. There is a 4 minute overlap on all sides of each area. Data format: AUSGeoid98 data files have a header record at the start of each file, to distinguish them from the superseded AUSGeoid93 data files. AUSGeoid98 data files show the geoid-ellipsoid separation to 3 decimal places, while the superseded AUSGeoid93 data files showed only 2 decimal places. AUSGeoid98 deflections of the vertical were computed from the geoid-ellipsoid separation surface, while the AUSGeoid93 deflections of the vertical were computed from OSU91A.

Some empirical relations for attenuation of ground-motion spectral amplitudes in Southwestern Western Australia

A dataset comprising some 260 seismograph and accelerograph records from 67 events of the Burakin 2001-02 earthquake sequence was compiled to develop regional ground-motion models for southwestern Western Australia. Events range in size from moment magnitude 2.3 - M - 4.6. The decay of spectral amplitudes can be approximated by a geometrical spreading coefficient of R-1.05 within 80 km of the source. The associated model for the regional seismic quality factor can be expressed as Q(f) = 290f1.09.
These attenuation parameters are subsequently used to evaluate average source parameters for the 67 earthquakes. For the observed magnitude range, data demonstrates a seismic moment (M0) - local magnitude (ML) relation following: log M0 = 1.14 ML + 10.45, where M0 is in N-m. Average corner frequencies for these events do not vary significantly with M0 particularly for events M &gt; 3.0, chiefly ranging between 2-3 Hz. This gives rise to anomalously low stress drops for lower magnitudes (M &lt; 4.0) that increase at larger magnitudes.

Siderophile and lithophile trace-element evolution of the Archaean mantle

Progressive depletion of several Archaean volcanic sequences in siderophile (Fe, Ti, Mn, V), lithophile (Zr, Sr, P, Y), and chalcophile (Zn, Cu) elements with higher stratigraphic level are reported for the Barberton Mountain Land (Tjakastad Subgroup) in South Africa, and are also observed in the eastern Pilbara Block (Western Australia), a number of sequences in the Yilgarn Block (Western Australia) and the Superior Province of Canada. These trends are shown by both high-Mg basalts and tholeiitic basalts, and are not dependent on the Mg number of the rocks. Because these variations are contrasted to the Skaergaard-type iron enrichment trend, and as they are unlikely to have been produced by secondary alteration, it is suggested they reflect secular depletion of source mantle regions following repeated extraction of basic partial-melt fractions. High-Mg basalts and peridotitic komatiites of the Tjakastad Subgroup are separated by compositional gaps for MgO, AI2O3, CaO, Ni and Co, as well as on the Ol-Op-Cp-Qz diagram, which militate against their relation by continuous crystal fractionation. Archaean high-Mg basalts are typically Qz normative, as distinct from picrites. Using the FeO-MgO (mol%) diagram, liquidus temperatures are estimated for the high-Mg basalts and komatiitic peridotites. The degree of partial melting (F) is deduced by mass balance calculation of FeO + MgO. Assuming olivine-dominated residues of partial melting, and using temperature-dependent Kd^MgO and Kd^FeO coefficients after Roeder and Emslie (1970), the mantle Mg number can be estimated. For the Archaean data, source Mg numbers fall mainly in the range 80-90, suggesting a relatively ferroan mantle. Computations of mantle trace-element levels are attempted, assuming equilibrium batch melting, normative residual mineral assemblages, and apply cited mineral/melt partion coefficients (D). The possibility of an Archaean mantle rich in iron, and possibly other siderophile elements, is supported by comparisons between Archaean and modern oceanic tholeiites. The distribution of mantle-melting events in space and time must have resulted in significant major- and trace-element heterogeneities. Subsidence of dense refractory mantle residues into undepleted regions may have triggered mantle diapirism, probably constituting a major factor underlying Archaean tectonic activity.
