TEM model studies of the Elura deposit, Cobar, New South Wales

A series of transient electromagnetic (TEM) scale-model studies of the Elura zinc-lead-silver deposit near Cobar, NSW, has been carried out. The results are generalised inasmuch as they are not restricted to the Elura deposit, but may be applied to other pipe-like bodies. A model of Elura was cast out of typemetal into a graphite mould, which simulated a conductive host rock. For both one-loop and two-loop geometries the response of the body at early times is masked by the host rock, and the response of the body at late times is two to three times background. By studying the fall-off of response with depth of burial, it was found that there is an optimum time range in which a conductive body can be detected. This time range depends on the conductivity and size of the body and the conductivity of the host rock. The optimum loop size for detecting a body in a resistive environment is slightly larger than the size of the body in plan. If the body is contained in a conductive host rock, then a smaller loop will minimise coupling with the host rock and will enable detection of the body over a wider time range. However the smaller loop also emphasises lateral inhomogeneities in the overburden. The response obtained with a two-loop system is more complex than for a coincident-loop geometry, and can be positive or negative in sign, depending on the sample time, loop separation, depth of burial of body, and host-rock conductivity. For loop separations less than the depth of the body, the two-loop response closely resembles the one-loop response.

Cooper Basin North, Qld, 2008 (P1176), 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 Cooper Basin North, Qld, 2008 survey were acquired in 2008 by the QLD Government, and consisted of 168416 line-kilometres of data at 400m line spacing and 60m 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.

These data are a digital representation of information depicted on printed maps from the Australia 1:250 000 Geological Series produced by AGSO and the Northern Territory Geological Survey (NTGS) between 1963 and 1998.  The data are in a tiled format 
and are not seamless, although basic edgematching has been done where possible.  Tiles are arranged according to the standard Australian 1:250 000 sheet breakup.  The complete dataset is comprised of the 90 tiles covering the Northern Territory.

Cooper Basin North Gravity Elevation geodetic

Digital Elevation data record the terrain height variations from the processed point- or line-located data recorded during a geophysical survey. This Cooper Basin North Gravity Elevation geodetic is elevation data for the Cooper Basin North Gravity Survey, Queensland 2007 (P200701). This survey was acquired under the project No. 200701 for the geological survey of QLD. The grid has a cell size of 0.0075 degrees (approximately 796m).  This grid contains the ground elevation relative to the geoid for the Cooper Basin North Gravity Survey, Queensland 2007 (P200701). It represents the vertical distance from a location on the Earth's surface to the geoid. The data are given in units of meters. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.

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.

1998 Yampi Shelf, Browse Basin Airborne Laser Fluorosensor Survey Interpretation Report : (WGC Yampi Survey)

The Yampi airborne laser fluorosensor (ALF) survey is located on the Yampi Shlef, Browse Basin. The survey was flown in several flights and sorties in November 1998. Sixty nine lines were acquired at 700 m spacing in a NW-SE direction. Line lengths ranged from 14.7 km to 74.6 km, with a total of 3,148.4 km acquired. A total of 2,149,037 spectra were collected at an average spacing of 1.38 m to 2.13 m. Of these 37 were selected as confident fluorescence spectra in the initial interpretation. 132 fluorescence spectra were picked on the second more detailed interpretation. A main cluster of fluors occur in the Londonderry-1 and Cornea Field region. This region also contains most of the fluors with the highest fluorescence / Raman area ratios, together with a high density of lower amplitude fluors.
