Helen Springs - Evadowns, NT, 1993 (P611), 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 Helen Springs - Evadowns, NT, 1993 (P611), radiometric line data, AWAGS levelled were acquired in 1993 by the NT Government, and consisted of 117753 line-kilometres of data at a line spacing between 300m and 500m, 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.

Bonaparte Gulf Gravity Survey Western Australia, 1959 By Gulf Oil Syndicate

This report describes a gravity survey conducted in the Bonaparte Gulf Basin, Western Australia, by Mines Administration Pty Limited, for Gulf Oil Syndicate, during September, 1959. The survey took place over part of Permit to Explore 127H. Simultaneously, a field geological reconnaissance along the western margin of the Basin was made by E.P. Utting, consulting geologist, to help evaluate the area.
The gravity survey was intended to extend a regional gravity survey of the southern and north-eastern portions of the Basin previously undertaken by the Bureau of Mineral Resources, Associated Australian Oilfields N.L., and Westralian Oil Limited.
Gravity values were observed and plotted over an area of approximately 1400 square miles, bordered on the north by Joseph Bonaparte Gulf and on the east by the Western Australia/Northern Territory border.
The gravity results have, to some extent, indicated the shape of the basement surface of that part of the Bonaparte Gulf Basin covered by Gulf Oil Syndicate's Permit to Explore 127H. Gravity stations are too widely separated to support the computation of a residual maximum. Bouguer "highs" are interpreted as features on the basin floor which may have encouraged Devonian reef development.

Cambrian and Ordovician rostroconch molluscs from northern Australia

Rostroconch molluscs are widespread and abundant in the Cambrian and Ordovician rocks of the Amadeus and Georgina Basins of northern Australia. Because the mollusc faunas of this area are largely unknown, this study concentrates on their systematics and biostratigraphic distribution. The work complements that of Pojeta, Runnegar (1976), who considered the known Cambrian and Ordovician rostroconchs from the rest of the world. We deal with 32 species, which are placed in 15 genera; 24 of the species are named and 8 are treated with open nomenclature. The 21 named species and 6 genera newly named here are: Ribeiria csiro sp. nov., R. hllckitta sp. nov., R. jonesi sp. nov., R. runnegari sp. nov., Apoptopegma dickinsi gen. novo et sp. nov., Cymatopegma semiplicatum gen. novo et sp. nov., Pinnocaris wellsi sp. nov., P. robllsta sp. nov., Ptychopegma burgeri gen. novo et sp. nov., Wanwania drllcei sp. nov., Technophorlls kempae sp. nov., T. nicolli sp. nov., T. planei sp. nov., T. walteri sp. nov., Kimopegma pinnatum gen. novo et sp. nov., Pallropegma gen. nov., Pleul'Opegma plicatum gen. novo et sp. nov., Tolmachovia beljordi sp. nov., Eopteria struszisp. nov., Euchasma caseyi sp. nov., E. skwarkoi sp. nov., and Bransonia chapronierei sp. Novo Twenty of the species are presently known only from the Georgina Basin, seven are known only from the Amadeus Basin, and five are common to both basins. The specimens were collected from 95 localities. The Australian occurrences are unusual in that 11 of the species are known from Upper Cambrian rocks; elsewhere in the world there are only four known species of rostroconchs in the whole Cambrian System. In the Cambrian rocks of Australia, four species of rostroconchs are known to occur in the Mindyallan Stage, one in the Idamean Stage, and seven in the Payntonian Stage. In the Australian Ordovician, ten species are known to occur in Datsonian rocks, four in Warendian rocks, and five in Arenigian rocks. Elsewhere in the world, most pre-Silurian rostroconchs occur in carbonate rocks; in Australia 14 of the known species occur in clastic rocks, and the remainder in carbonate rocks.

Cainozoic geology and geomorphology of the Wahgi Valley, central highlands of Papua New Guinea

The Wahgi Valley is a structural depression, between the Bismarck Fault Zone to the north and the Kubor Anticline to the south, which has been enlarged by erosional removal of northward-dipping sedimentary rocks on the northern flank of the Kubor Anticline. The geomorphic history of the area began when it became land about 35 Ma ago. The Wahgi Valley contains volcanic debris avalanche and lahar deposits in the west and fluviatile/ lacustrine deposits elsewhere.  The latter are dominated by undissected swamp and lake deposits in the west, and dissected fan and terrace deposits in the east. There is clear evidence of knick point retreat up the Wahgi River from the east, causing the fans to trench progressively from the east. Earlier interpretations of the evolution of the Wahgi Valley stressed drainage reorganisation, with reversal of a westerly flowing Wahgi River caused by damming by volcanics in the west, and capture in the east.  Evidence from sediments, tephra, and landforms now suggests that reversal was probably restricted to the westernmost drainage, and any reversal of drainage occurred earlier than previously thought, perhaps 400 000 years ago.

L038 Quilpie-Eromanga seismic reflection survey, QLD, 1959

A reconnaissance seismic survey was made in the area of Quilpie and Et.omanga in south-western Queensland. Traverses crossed the Harkaway, Pinkilla, and Tallyabra Domes. Reflection horizons were correlated with horizons within the Mesozoic sediments, and one persistent reflection was correlated
with a horizon near the top of the Palaeozoic sediments. A thickness of sediments of up to 15,000 ft, including up to 11,000 ft of Palaeozoic rocks, was indicated on the flanks of the Harkaway and Pinkilla Domes. Results were compared with existing gravity data. Suggestions of faulting are based on seismic and gravity evidence taken together and also on gravity evidence alone in locations not covered by the seismic work.

Gawler Craton Airborne Survey Tranche 3 Magnetics / Radiometrics / Elevation

The Geological Survey of South Australia commissioned the Gawler Craton Airborne Survey (GCAS) as part of the PACE Copper initiative. The airborne geophysical survey was flown over parts of the Gawler Craton in South Australia. The program was designed to capture new baseline geoscientific data to provide further information on the geological context and setting of the area for mineral systems (http://energymining.sa.gov.au/minerals/geoscience/pace_copper/gawler_craton_airborne_survey). 

The survey design of 200 m spaced lines at a ground clearance of 60 m can be compared with the design of previous regional surveys which generally employed 400 m line spacing and a ground clearance of 80 m. The new survey design results in ~2 x the data coverage and ~25% closer to the ground when compared to previous standards for regional surveys in South Australia.

MRTAS NE Tasmania tmi grid geodetic

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.
This MRTAS NE Tasmania tmi grid geodetic has a cell size of 0.001 degrees (approximately 97m). The units are in nanoTesla (or nT). The data used to produce this grid was acquired in 1989 by the TAS Government, and consisted of 2755 line-kilometres of data at 500m line spacing and 243m terrain clearance.
