SAEI (MESA) - Broken Hill Exploration Initiative, Area BHEI-1, 1995 (P750), 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 SAEI (MESA) - Broken Hill Exploration Initiative, Area BHEI-1, 1995 (P750), radiometric line data, AWAGS levelled were acquired in 1995 by the SA Government, and consisted of 62674 line-kilometres of data at 100m 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.

Broken Hill (Detail), NSW, 1975 (P421), 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 Broken Hill (Detail), NSW, 1975 survey were acquired in 1975 by the NSW Government, and consisted of 14118 line-kilometres of data at 300m line spacing and 100m 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.

AUSGeoid98 v.1.0 data files:  (sk56-07)

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.

BMR Cruise 067 : Otway Basin and West Tasmanian Sampling

In early 1987, scientists aboard R.V. Rig Seismic carried out a 29 day research cruise over the Otway Basin and the Sorell Basin of the west Tasmanian margin, to provide new geological, geochemical and heatflow data, in an area with considerable petroleum potential. Altogether, 130 sampling stations were occupied using dredges, corers, grabs and a heatflow probe.
Among the rocks recovered were: Palaeozoic volcanics and metasediments; Late Cretaceous sandstones, siltstones and mudstones; early Tertiary siltstones; and late Tertiary carbonates. All samples were taken along seismic profiles, so that the results can be easily incorporated into the regional geological framework. In general, the further down the continental slope, the older the rocks. Palaeontological results indicate that there has been very considerable post-Eocene subsidence of the slope. A great variety of Quaternary sediments were recovered, and these have allowed a detailed sedimentation model to be developed.
Heatflow calculations from 20 stations suggest that the present zone of thermal maturation of hydrocarbons is 2-4 km deep. Headspace gas analyses of many cores indicate that thermogenic hydrocarbons are widespread, with particularly high readings in both the eastern and the western Otway Basin and on the west Tasmanian margin. Thus, mature hydrocarbon source rocks must also be widespread.

Summary of Phanerozoic Biostratigraphy and Palaeontology of the Canning Basin (Lennard Shelf)

Palaeontological and biostratigraphic studies for each Phanerozoic system are briefly summarised for the entire Canning Basin, with emphasis on the Palaeozoic. Biostratigraphic analysis of sixkey wells on the Lennard Shelf (May River 1, Langoora 1, Meda 1, Meda 2, Blackstone 1 and.Mimosa 1) are given in an Appendix. A synthesis of this information has led to the identificationof ten major stratigraphic breaks within the Palaeozoic succession on the Lennard Shelf:
1.The entire Cambrian Period and most of the Tremadocian.
2.Much of the Silurian and the Early Devonian (resulting from an Early Silurian age for theWorral Formation, and a Late Ordovician - earliest Silurian age for the underlying CarribuddyGroup).
3.Within the early Famennian (a break of variable duration in different parts of the study area).
4.WI&amp; the late Famennian (corresponding to the Upper postera, and Lower expansa conodontZones).
5.Within the latest Famennian (Strunian - possibly representing the global sea-level fall in theMiddle praesulcata Zone, just prior to the WC boundary).
6.Within the latest Toumaisian-early Visean (between the Laurel Formation and the AndersonFormation; the least plausible stratigraphic break).
7.Within the latest Visean-early Namurian (representing the maculosa assemblage).
8.The late Westphalian and most or all of the Stephanian (representing the birkheadensis Zone).
9.The early part of the Sterlitamaldan Stage (between the base of the Nura Nura Member of thePoole Sandstone, and the top of the Grant Group.
10.The latest Permian (Dorashamian = Changhsingian) Stage (representing the
Protohaploxypinus microcotpus Zone; between the upper part of the Hardman Formation and thelower part of the Blina Shale).
Biostratigraphic control provided by conodonts, ostracods, naicrovertebrates and spores hasunderpinned AGSO sequence analyses of seismic and well data for a new interpretation of theoutcropping and subsurface Late Devonian reef complexes. Revised ages effect theunderstanding of the petroleum resource potential in the Ordovician sequence. Some formationswithin the Carribuddy Group may behave as effective seals to source and reservoir rocks in theNita Goldwyer Formations.
