Gympie, QLD, 1987 (P542), 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 Gympie, QLD, 1987 (P542), radiometric line data, AWAGS levelled were acquired in 1987 by the QLD Government, and consisted of 13720 line-kilometres of data at 1500m line spacing and 150m 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.

Reference lines, fault classification, transform systems and ocean-floor spreading: discussion

Wellman (1971) has presented erroneous data relating to lineaments in Papua New Guinea. The main faults and folds in Papua New Guinea as determined by ground and remote sensing surveys by the Bureau of Mineral Resources, the Geological Survey of Papua New Guinea and by oil exploration companies are shown on the new BMR - GSPNG 1:1,000,000 Scale geological map of Papua New Guinea.
Wellman (1971) in a recent issue of this journal produced an account of fault systems in the Pacific region. However, his Figure 5and related text (p.205) cannot go unchallenged in so far as they refer to the eastern part of the island of New Guinea, i.e., Papua New Guinea.
An example of the inaccuracy of Figure 5 (Wellman, 1971), is the omission of major faults such as the Owen Stanley Fault (Fig.1) and the Frieda Fault (Fig.2), and the depiction of a non-existent major fault system (which he called the New Guinea Fault).
Exhaustive examinations of airphotos, both vertical and oblique, at scales from 1:20,000 to 1:80,000, and of side-looking airborne radarimagery, by numerous officers of the Bureau of Mineral Resources and theGeological Survey of Papua New Guinea during the last 5 - 10 years have failed to detect the lineations shown by Wellman. Furthermore, these studies, and extensive field mapping by government and oil exploration company geologists over the last 25 years, have revealed the existence
of the fault and fold systems shown here in Figures 3a and 4.
Although a strike slip type of movement is suspected for some of these faults only vertical movements have been proved. Thus the sinistral movement claimed for the imagined "New Guinea Fault" should not be regarded as typical of the fault system of Papua New Guinea.

Broken Hill Gravity (P199423), gravity point data

Gravity data measures small changes in gravity due to changes in the density of rocks beneath the Earth's surface. 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 Broken Hill Gravity (P199423) contains a total of 2238 point data values acquired at a spacing between 20 and 100 metres. The data is located in NSW and were acquired in 1987, under project No. 199423 for CRA Exploration Pty Ltd.

Pine Creek - Kombolgie VTEM AEM Survey, NT, 2009 Final Data (P1195)

During 2008 and 2009, and under the Australian Government's Onshore Energy Security Initiative, Geoscience Australia acquired airborne electromagnetic (AEM) data over the Pine Creek Orogen of the Northern Territory. The survey area was split into three areas for acquisition. VTEM data was acquired in the Kombolgie area east of Kakadu National Park (this data set) between August and November 2008. TEMPEST data was acquired west of Kakadu National Park with the area split in two to facilitate the use of two aircraft: the Woolner Granite area in the north was acquired between October and December 2008; and the Rum Jungle area adjoining to the south, was acquired between October 2008 and May 2009. The main purpose of the surveys was to provide additional geophysical / geological context for unconformity style uranium mineral systems and thereby promote related exploration. The survey data will also provide information on depth to Proterozoic/Archean basement, which is of general interest to explorers, and will be used as an input into ground water studies in the region.
The data are available in two parts:


Part A, which consists of Grids (4MB) + Multiplots (85MB) + Report (8MB) + Waveform (43 MB) is available as a free download


Part B, which consists of Part A [Grids (4MB) + Multiplots (85MB) + Report (8MB) + Waveform (43 MB)] plus Line data. Together they are too large for web downloading and therefore Part B is only available, on DVD.

L021 Broome seismic reflection survey, WA, 1955

The Bureau of Mineral Resources conducted a seismic reflection survey of a small area near Broome, W.A., during 1954 and 1955. It was part of a general investigation of the Canning Basin and was aimed at determining the distribution of sediments south of the Fenton Fault. The seismic work indicated a sedimentary thickness of at least 6000 feet, and probably as much as 10,000 feet could be expected. It
also showed that the subsurface formations are probably folded and faulted.

Summary Of Data And Results Drilling Operations In The Murray Basin New South Wales And South Australia 1961-1962 Of Australian Oil And Gas Corporation Limited Woodside (Lakes Entrance) Oil  Company N.L. And Australian Oil Corporation

A.O.G. Wentworth No. 1 Well was located in the Murray Basin, approximately 20 miles north of Wentworth, New South Wales. The well was drilled by W.L. Sides and Son Pty Limited for Australian Oil and Gas Corporation Limited to a total depth of 2081 feet. Drilling commenced on 8th September, 1961, and was completed on 14th October, 1961. A programme of coring and electric logging using a Widco unit was carried out, but no perforating, squeeze cementing, or testing operations were undertaken.
The well was drilled to determine the nature of the sediments immediately beneath the Tertiary sequence, with particular reference to a refractor at a calculated depth of 1650 feet. This was thought to be basement before drilling started, but it was not identified during logging.
The well penetrated 192 feet of Quaternary sands and grits; 1081 feet of Tertiary sands, silts, clays, marls, and limestones; 331 feet of Lower Cretaceous sediments, including Roma Formation Equivalents; 451 feet of Permian sandy mudstones; and bottomed in conglomerate of possible Permian age.
No shows of hydrocarbons were observed during the drilling operation. In the New South Wales part of the Murray Basin, Lower Cretaceous sediments had not been previously recorded, and Permian sedimentation had been recorded in only one area, between Oaklands and Coorabin, some 250 miles east of Wentworth No. 1 Well.
The off-structure drilling operation at A.O.G. Wentworth No. 1, New South Wales, was subsidized under the Petroleum Search Subsidy Act I!lS!l, from surface to total depth.

Wiso Basin trav02, NT, 2000 (P1015), 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 Wiso Basin, NT, 2000 survey were acquired in 2000 by the NT Government, and consisted of 113520 line-kilometres of data at 400m 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.
