Report on visits to USA and Canada, 1961 (with particular reference to methods of aeromagnetic interpretation)

Between January and March 1961 an official visit was made by the author to certain government organisations, oil companies, and airborne survey contracting companies in U.S.A. and Canada. The purpose of the visit was to study techniques of interpretation of aeromagnetic data, particularly in relation to oil exploration, and to attend a course in aeromagnetic interpretation at the United States Geological Survey in Washington. This Record contains the notes on discussions with specialists of the various organisations. Notes on other matters such as analysis of magnetic properties of rocks, properties of sedimentary rocks, age determinations of rocks, analysis of oil samples, and problems in interpretation of gravity data are also included.

Iron ore occurrences under investigation by Nevsam Mining Co Pty Ltd October, 1961

Seven areas of iron ore occurrences under investigation by Nevsam Mining Company Pty. Ltd. were examined by the writer. One area contains hematite rubble; three areas are thought to be gossanous lodes; one area contains iron as surface enrichments, banded iron formation, and magnetite schist; and two areas are thought to be surface enrichments, although one of these last two may be a sedimentary hematite deposit. Little exploratory work has been done except for part of the rubble occurrence, and it is not possible to give any estimates of tonnage or grade except for part of the rubble area, where there may be between 30,000 and 40,000 tons of ferruginous material per vertical foot. The depth is not known, but it is probably not much greater than ten feet. The rest of the rubble area, the three gossanous areas, and the possible sedimentary hematite deposit all warrant some exploratory work.

Huon River/Black Fish Creek dam site geophysical surveys, Tasmania 1959-60

This Record describes seismic refraction and resistivity traversing surveys carried out at the request of the Hydro Electric Commission of Tasmania at a proposed dam site on the Huon River, up stream from its junction with Blackfish Creek. The purpose of the surveys was to determine the nature and thickness of the overburden and the nature of the bedrock. The overburden consists of scree material, sand, soil, clay, and weathered and recemented dolerite. In many places the seismic velocity in the weathered and especially the recemented dolerite indicates that these rocks are of sufficient strength for foundation purposes. Seismic results indicate that the overburden thickness ranges from 20 to 316 ft. Over most of the area, the estimated average overburden thickness is about 70 to 80 ft, although over about one sixth of the area the estimated overburden thickness ranges from 130 to 316 ft. The greatest thickness is indicated on the western bank. The bedrock consists mainly of unweathered dolerite, although the seismic velocities and drilling data indicate that the bedrock corresponds, in some instances, to partly weathered or recemented dolerite. It is estimated that the depth to bedrock has been calculated within 30 per cent.

Great Lake power development geophysical surveys, Tasmania 1957/59

Results are given of two geophysical surveys carried out by the Bureau of Mineral Resources for the proposed Great Lake Power Development on behalf of the Hydro-Electric Commission of Tasmania. In the 1957-58 survey seismic reflection, seismic refraction, resistivity, gravity, and magnetic methods were used. Although no reflections were recorded from the bottom of the dolerite sill, the magnetic and seismic surveys provide supporting evidence for features indicated by the interpretation of a gravity survey in 1951. In the 1959 survey a new tunnel line was investigated with seismic refraction, gravity, magnetic, and resistivity methods. Estimates are made of the thickness of scree material, glacial deposits or weathered layers. Some shear zones were located and information was obtained on the nearly vertical subsurface boundary between sediments and dolerite.

Wild River/Millstream Dam site, geophysical survey, Queensland 1960

This Record describes a geophysical survey at a dam site which was undertaken in response to an application from the Irrigation and Water Supply Commission of Queensland. The dam will be used for water conservation. The seismic method was used to measure the seismic velocities in different rock types and to determine the depth to rock discontinuities; some magnetic and resistivity work was done to determine the boundaries of a basalt flow, and to disclose the presence of shear zones.

Geological reconnaissance of the Rawlinson-Macdonald area, Western Australia

Geological reconnaisance on the Macdonald and Rawlinson sheet areas has shown an aggregate thickness of 27,000 feet of Precambrian sedimentary rocks. These rocks have been divided into Lower and Upper Proterozoic but only on the north-east corner of the Macdonald sheet is the unconformity between the two sequences visible. Possible Archaean gneiss and quartzite have also been differentiated in the north-east Macdonald area, These rocks are similar to those in the Arunta Complex of the Alice Springs area. No relationship is visible between these rocks and those mapped as Lower Proterozoic.

Mesozoic strata of the Calvert Hills 1:250 000 sheet

Lower Cretaceous strata of the Calvert Hills 1:250,000Sheet area were examined during the 1961 field season. Field observations of lithologies and their sequences together with the collection of fossils and their identification provided material for this Record. Fossil content and field observations suggest that Mesozoic sediments on the Calvert Hills 1:250,000 Sheet area were deposited in distinct environments at three different times in the Lower Cretaceous

Micropalaeontology of samples from bore No 9285, 'Herwart Downs' via Tibooburra, New South Wales

Nineteen samples were submitted by the Water Conservation and Irrigation Commission of New South Wales, from Bore No.92859on Mr.W.J. Davis property Hewart Downs via Tibooburra in north-western New South Wales. This bore is located at 29 36'S,141 17'E. Samples were taken at 50 feet intervals between the depths of 250 feet and 1100 feet. Operations have ceased at the moment, because of mechanical troubles. However, the Water Conservation and Irrigation Commission are hopeful that the bore will be continued Any palaeontological information that can be derived from bores in this part of New South Wales is important.. at the present time, because it helps in the elucidation of the subsurface stratigraphy of the Lower Cretaceous in that part of the Great Artesian Basin. An excellent suite of Lower Cretaceous foraminifera, especially calcareous species, is present from 450 feet down to 1100 feet. Further support for a Lower Albian age for these beds is given by the occurrence of the megaspore pyrobolospora, reticulata Cookson and Dettman, 1958 (determined by P.R. Evans)which is characteristic of subsurface Lower Albian beds in bores in South Australia, Victoria, New South Wales and Queensland.

Red Tank bore gravity survey, Plenty River, Northern Territory 1960

This Record describes a geophysical survey in the Plenty River area to test the efficacy of the gravimetric method in locating buried river channels. The results appear to indicate such a buried feature but the evidence is inconclusive. If subsequent bore-hole evidence confirms the presence of this buried channel the gravimetric method may be more widely used for this type of work.

Revisions to the stratigraphy of Hay River, Huckitta and Tobermory 4-mile Sheets, Northern Territory

This report outlines corrections and additions to previous mapping on the Huckitta, Hay River and Tobermory Four-mile Sheets, Northern Territory, and presents all available data on water bores drilled in those areas. On the May River Sheet, Upper Cambrian and Lower Ordovician sediments on the western limb of the Toko Syncline are faulted against Upper Proterozoic sediments along a complex north-west trending fault zone named the Toomba Structure. The maximum throw of the main fault exceeds 2,000 feet, and there are smaller, parallel strike faults which affect Middle Ordovician sediments. A section of 460 feet was measured in a ? Ordovician sandstone sequence which overlies the Middle Ordovician Mithaka Beds. Samples obtained from several water bores along the Field River show the presence of a locally non-outcropping sequence, probably the Tarlton Formation, overlying the Upper Proterozoic Field River Beds. On the Tobermory Four-mile Sheet, the effects of lateritisation on the mixed lithologies of the Upper Cambrian and Lower Ordovician units were unravelled, and it was shown that the change from the Tomahawk Beds of the Huckitta area to the Ninmaroo and Kelly Creek Formations of the Toko Range is a facies variation. A. small disconformity was established between the Nora Formation and the Carlo Sandstone in the Tarlton Range. Numerous measurements in the Tarlton Range show that during the deposition of the Carlo Sandstone currents came from the south-east. Further plant fossils were collected from the Tarlton Formation; they indicate a probable Triassic or early Jurassic age. On the Huckitta Four-mile Sheet, two sections of about 750 feet were measured in the predominantly dolomitic Arthur Creek Beds, in the area west and South west of Huckitta homestead; in one section, trilobites and brachiopods were discovered 85 feet, stratigraphically, above archaeocyathids in the top of the Lower Cambrian Mount Baldwin Formation. Three new fossiliferous horizons were found in the Upper Cambrian Arrinthrunga Formation; one is near the base and contains trilobites of lower Upper Cambrian age; the other two horizons are near the top of the formation and contain trilobites and brachiopods. Revised structural mapping and measurement of new sections show that the Arrinthrunga Formation is about 3,200 feet thick. The Middle Ordovician Nora Formation which occurs only in the southern foothills of the Dulcie Range, has been mapped as a separate unit from the Tomahawk Beds which formerly included it .Additional samples of Devonian fish were collected from a new locality in the Point Spring area.

Gippsland Basin airborne magnetic surveys, Victoria 1951-52 and 1956

The Bureau of Mineral Resources, Geology and Geophysics made an aeromagnetic survey of the on-shore area of the Gippsland Basin, Victoria, in 1951-52 and of the off-shore area in 1956. The anomaly trends of the aeromagnetic map can be correlated with several known geological structures in the Basin, some of which can be traced by their magnetic characteristics into the deeper parts of the Basin. A contour map of estimated depths to magnetic basement rock shows a trough east of Lake Wellington containing probably 15,000 feet of sediments. Depth estimates in parts of the south-western corner of the Basin are uncertain because of the presence of magnetic basalt flows in the sedimentary sequence

Land Systems of Tasmania

Tasmania was separated into seven regions for the purposes of land system mapping for the period 1978-1989.  Non-unique land systems were developed based on six descriptor classes (geological period, geological rock type, rainfall, vegetation, elevation, and differences in dominant soils.  Within each land system, land components are described which present examples of soil and vegetation variation across topographic sequences (proportion estimates, but unmapped boundaries).  Land Systems are considered to have a nominal scale of 1:100 000.

Regions were mapped separately (as below), and amalgamated to form a digital statewide coverage:

Land Systems of Tasmania Region 1: King Island.
Land Systems of Tasmania Region 2: Flinders Island.
Land Systems of Tasmania Region 3: North.
Land Systems of Tasmania Region 4: North East
Land Systems Survey of Tasmania Region 5: Central Plateau.
Land Systems Surveys of Tasmania Region 6: South, East and Midlands
Land Systems of Tasmania Region 7: South West.

Growing Degree Day Daily Accumulation Maps

A statewide grid surface (80m spatial resolution) delineating Degree Day accumulation across the state of Tasmania is produced daily for the Tasmanian growing season (i.e. between months October through to April). The outputs are dynamic with the map products updated daily. Three map products are produced:

1) Growing Degree Day Heat Accumulation Tracker - Current Season: GDD accumulation to date (refer to link below) for the current growing season (updated daily)

2) Growing Degree Day Heat Accumulation Tracker - 10 year average: GDD accumulation to date (refer to link below) based on the 10 year average (i.e. averaged GDD units garnered from data 10 years prior to the current growing season; updated daily)

3) Growing Degree Day Anomaly - Current season vs 10 year average: The difference between 1) and 2) where negative values indicate that the current growing season is cooler relative to the 10 year average, positive values indicate a warmer season.

Map outputs are based on daily records produced from 43 Bureau of Meteorology (BoM) Automatic Weather Station sites with further bias correction provided by 267 independent air temperature logger recording sites (courtesy of the Tasmanian Government Department of Primary Industries, Parks, Water and Environment (DPIPWE)). For operational real-time application, the mapping was fully automated in the R programming language and hosted on a cloud-based computing platform courtesy of Sense-T and hosted on the high performance computing cluster provided by the Tasmanian Partnership of Advanced Computing (TPAC) of the University of Tasmania.
