Menzies, WA, 1964 (P288), 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 Leonora-Menzies, WA, 1964 survey were acquired in 1964 by the WA Government, and consisted of 24132 line-kilometres of data at 1600m 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.

Northern Bonaparte Basin Biozonation and Stratigraphy Chart No.15

Biostratigraphy is the branch of stratigraphy that uses fossils to establish relative ages of rock and correlate successions of sedimentary rocks within and between depositional basins. A biozone is an interval of geologic strata characterised by certain fossil taxa. Such intervals are often defined by the first appearances (range bases), apparent extinctions (range tops/last appearances), or abundances of fossil index species. These key index species should be relatively abundant, short-lived taxa that are easy to recognise and as geographically widespread as possible. Widely used fossil groups include brachiopods, conodonts, dinoflagellate cysts, foraminifera, graptolites, nannofossil, spores and pollen and trilobites. Zonal schemes based on several different fossil groups can be used in parallel, and the zones can be calibrated to the absolute geological timescale using tie points to rocks which have been radio-isotopically dated.

Flood Damage Estimation Beyond Stage-Damage Functions - An Australian Example

There are a number of factors which influence the direct consequence of flooding. The most important are depth of inundation, velocity, duration of inundation and water quality. Though computer modelling techniques exist that can provide an estimate of these variables, this information is seldom used to estimate the impact of flooding on a community. This work describes the first step to improve this situation using data collected for the Swan River system in Perth, Western Australia. Here, it is shown that residential losses are underestimated when stage-damage functions or the velocity-stage-damage functions are used in isolation. This is because the functions are either limited to assessing partial damage or structural failure resulting from the movement of a house from its foundations. This demonstrates the need to use a combination of techniques to assess the direct economic impact of flooding.

L061 St George-Eulo seismic reflection and refraction survey, Great Artesian Basin, QLD, 1962

A seismic aluvey was made between St George and the Queensland/South Australia border in the latter half of 1962. The results of the part of the survey over the Surat Basin, the Nebina Ridge, and the Eulo Shelf are presented in this Record. The survey aimed at providing information on the nature and structure,of the rocks underlying the Mesozoic sediments of the Great Artesian Basin, in particular across the Nebine Ridge and Eulo Shelf. The results of the survey between St George and Bollon indicated a sedimentary section of the order of 5000 ft overlying a basement rock of either metamorphic or igneous origin. The-deepest section recorded was of about 5700 ft, about 12 miles west of St George and probably corresponds to the Boolba Trough suggested by Jenkins (1958). The sedimentary section becomes gradually thinner westward as the Nebine Ridge is approached and about 3000 ft of sediments were recorded about ten miles west of Bollon. A reflection traverse northwards along the axis of the Boolba Trough indicated a thinning of sedimentary  section of about 40 ft per mile. No structural explanation for a magnetic lineament interpreted from aeromagnetic work was found. Velocities of over 19,000 ft/s were recorded from granitic rocks at shallow depths over the Nebine Ridge. A velocity of 19,500 ft's was measured close to a granite outcrop at Eulo. A thickening of the sedimentary section between the Eulo Shelf and Nebine Ridge was confirmed by refraction shooting and depths indicated that the total section (3300 ft) was not significantly greater than the depth of the water bores. No apparent development of the trough to the north or west was indicated.

Notes of the occurrence of piezo-electric quartz in Australia with special reference to the Kingsgate field

For a time during the war it appeared that there would be an acute shortage of piezo-electric quartz in Australia. Accordingly it was necessary to investigate all known deposits and reported occurrences of quartz, with a view to seeing whether further or new development was possible. This work was the responsibility of the Controller of Minerals Production, Mr. J. Malcolm Newman, who placed the investigation in the hands of North Broken Hill Limited. A considerable part of the bulletin deals with the Kingsgate area, New South Wales, from which noteworthy quantities of quartz crystals have been obtained and which is still considered to be the most promising area for crystal in Australia. Mr. Garretty's conclusions about this field should prove of general interest and the presentation of his results will provide a basis for future prospecting.
