A potential dolostone reservoir in the Georgina Basin: the Lower Ordovician Kelly Creek Formation

The extensive, dolostone unit of the Lower Ordovician Kelly Creek Formation in the Toko Syncline, Georgina Basin, has significant potential as a hydrocarbon reservoir with variable porosity and permeability characteristics. The porous dolostone is 107 metres thick. Measured porosities of 19 core plugs from this section average 11 per cent, average horizontal permeability (gas) was 234 md, and vertical permeability (gas) 28 md. Permeability is more variable vertically, being generally low but with random higher values. Porosity is dominantly intercrystalline in mottled and stratified distribution, with associated vug, channel, fracture and breccia types; the porosity developed late in diagenesis, during and after pervasive dolomitisation of the sequence. The dolostone interdigitates with overlying thin calcareous dolomitic sandstone beds which have higher porosity (19%) and permeability (KaH 270 md, KaV 54 md). Traces of liquid hydrocarbons in the dolostone and previously reported gas flows from the overlying sandstone in AOD Ethabuka No. 1 indicate significant potential for these porous units as a reservoir in suitable structural traps.

Cretaceous stratigraphy and palaeontology of the Northern Territory

Most of three field seasons (1960-1962) were spent examining the Cretaceous sediments and fossils of the northern portion of the Northern Territory. These sediments were traced into north-western Queensland. In addition I spent the 1963 winter season in the field as a member of a field party which, under the leadership of A. T. Wells, mapped a large area between Alice Springs and the South Australian border. My task on that occasion was the mapping of the post Devonian sediments on the Kulgera and Finke 1: 250,000 Sheet areas; these sediments include the Cretaceous Rumbalara Shale. The bulk of the first part of this Bulletin is devoted to the presentation of geological data on the Cretaceous sediments of the northern portion of,the Northern Territory, which will be presented under the title of Mullaman Beds. The Cretaceous fossils are described in Part 2 (p. 53 onwards). Many conclusions reached and presented in this Bulletin would not have been possible without datings obtained from fossils collected during the survey. The Cretaceous sediments of the Northern Region are contained in about fifty 1: 250,000 Sheet areas. Outcrops are scarce or hard of access over much of, this region, and more time could profitably be spent collecting additional information. Approximations made for lack of time in the field will become apparent with more detailed work in future years. The Cretaceous sediments of the Southern Region are much less complex; they are briefly described under the titles of Rumbalara Shale and sediments of the Hay River area. The ages of the subdivisions are given in general terms, because the faunas do not permit precise determination in terms of standard zones (see Fig. 24).

AUSGeoid98 v.1.0 data files:  (sh49-11)

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.

Lake Mason, WA, 1995 (P770), radiometric line data, AWAGS levelled

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 Lake Mason, WA, 1995 (P770), radiometric line data, AWAGS levelled were acquired in 1995 by the WA Government, and consisted of 12767 line-kilometres of data at 200m 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.

NETGOLD - Fingal, TAS, 1993 (P783), 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 NETGOLD - Fingal, Pipers River, Mt.Horror, TAS, 1993 survey were acquired in 1993 by the TAS Government, and consisted of 16797 line-kilometres of data at 200m line spacing and 80m 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.

Archean alkaline and related igneous rocks of Australia

Alkaline and related rocks are a relatively rare class of igneous rocks worldwide. Alkaline rocks encompass a wide range of rock types and are mineralogically and geochemically diverse. They are typically though to have been derived by generally small to very small degrees of partial melting of a wide range of mantle compositions. As such these rocks have the potential to convey considerable information on the evolution of the Earth’s mantle (asthenosphere and lithosphere), particularly the role of metasomatism which may have been important in their generation or to which such rocks may themselves have contributed. Such rocks, by their unique compositions and or enriched source protoliths, also have considerable metallogenic potential, e.g., diamonds, Th, U, Zr, Hf, Nb, Ta, REEs. It is evident that the geographic occurrences of many of these rock types are also important, and may relate to presence of old cratons, craton margins or major lithospheric breaks. Finally, many alkaline rocks also carry with them mantle xenoliths providing a snapshot of the lithospheric mantle composition at the time of their emplacement.
Accordingly, although Alkaline and related rocks comprise only a volumetrically minor component of the geology of Australia, they are of considerable importance to studies of lithospheric composition, evolution and architecture and to helping constrain the temporal evolution of the lithosphere, as well as more directly to metallogenesis and mineralisation.
This contribution presents the first part of an ongoing compilation of the distribution and geology of alkaline and related rocks throughout Australia. The report and accompanying GIS document alkaline and related rocks of Archean age. All are from the Pilbara and Yilgarn Cratons of Western Australia. The report also reviews the nomenclature of alkaline rocks and classification procedures. GIS metadata is documented in the appendices.

Results from the application of TanDEM-X Intermediate DEM for terrain illumination correction of Landsat data

Effective correction of remotely sensed data for terrain illumination effects over mountainous areas, requires Digital Elevation Model (DEM) data at an appropriate resolution and quality. Conversely, the performance of terrain illumination correction and scale-based analysis could be used to evaluate the quality of DEM data used for the correction. In this study, TanDEM-X Intermediate DEM (IDEM) data at 12 m resolution and the 1-arc second Shuttle Radar Topography Mission (SRTM) data were used independently to evaluate the relative effectiveness of the terrain illumination correction for Landsat 8 optical data over Tasmania, Australia.  Results from the terrain illumination correction and filter bank analysis show that IDEM 12 m data can resolve finer details of terrain shading than the SRTM based DEM and deliver better results in areas with detail-rich terrain.  However, in the data available for this study, spikes and other noise artefacts were prevalent, especially over areas covered by water; removal of such noise artefacts would increase the utility of the IDEM for operational correction of terrain illumination effects in optical satellite data.
