Sir Samuel 1:250 000 topographic map

This map is part of the series that covers the whole of Australia at a scale of 1:250 000 (1cm on a map represents 2.5 km on the ground) and comprises 513 maps. This is the largest scale at which published topographic maps cover the entire continent. Each standard map covers an area of 1.5 degrees longitude by 1 degree latitude or about 150 kilometres from east to west and 110 kilometres from north to south. There are about 50 special maps in the series and these maps cover a non-standard area. Typically, where a map produced on standard sheet lines is largely ocean it is combined with its landward neighbour. These maps contain natural and constructed features including road and rail infrastructure, vegetation, hydrography, contours (interval 50m), localities and some administrative boundaries. The topographic map and data index shows coverage of the sheets. Product Specifications Coverage: The series covers the whole of Australia with 513 maps. Currency: Ranges from 1995 to 2009. 95% of maps have a reliability date of 1994 or later. Coordinates: Geographical and either AMG or MGA (post-1993) Datum: AGD66, GDA94, AHD. Projection: Universal Traverse Mercator (UTM) Medium: Paper, flat and folded copies.

GSWA Kurnalpi North Potassium Grid Geodetic

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 radiometric potassium grid has a cell size of 0.00021 degrees (approximately 22m) and shows potassium element concentration of the Kurnalpi North, WA, 2013 in units of percent (or %). The data used to produce this grid was acquired in 2013 by the WA Government, and consisted of 92672 line-kilometres of data at 100m line spacing and 50m terrain clearance.

Arafura and Money Shoals Basins Biozonation and Stratigraphy Chart No. 3

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.

Rapid national hydrogeology assessment framework for groundwater prospectivity and vulnerability: Timor-Leste case study

Timor-Leste’s economy and the livelihood of its people are dependent on groundwater. In Timor-Leste these groundwater resources are replenished by rainfall in the wet season providing storage for use throughout the year. Greater demand for groundwater in Timor-Leste from increases in population, industry and agriculture has caused a strain on this resource and its current prospectivity and sustainability is largely unknown. This study has developed a rapid national hydrogeology assessment framework for consistent groundwater system understanding that can inform future development of the resource.
This study has brought together national datasets as well as collected new data in three cases study sites. Case study locations are representative of the three principal aquifer types identified in the hydrogeology mapping. Fieldwork at each of the case study sites involved: 1) ground-truthing of aquifer characteristics, 2) ground-based electromagnetic geophysical (TEM) surveys to delineate aquifer architecture and groundwater conductivity, and 3) direct measurement of groundwater levels and hydrogeochemistry.
The hydrogeology framework was designed to simply and clearly demonstrate how existing and new datasets can be rapidly combined to produce consistent information and maps for groundwater prospectivity and vulnerability. The framework allows for limited groundwater information by using surrogate datasets for initial assessments through a system based (knowledge) approach. The framework also allows for incorporation of detailed site-specific groundwater measurements and information to the national scale (data approach). The method and datasets are transparent to permit the user to define data inputs and weightings. The framework has been applied to Timor-Leste to produce a national hydrogeological map that in turn informed an assessment of groundwater vulnerability.
Through the development of a rapid national hydrogeology assessment framework, Timor-Leste now has a consistent national hydrogeology map. This framework enables the incorporation of new knowledge and data, as it becomes available over time, and can be applied to multiple scales including continents such as Australia.

Summary Of Data And Results Gippsland Basin, Victoria Southwest Bairnsdale No. 1 Well Duck Bay No. 1 Well Of Woodside (Lakes Entrance) Oil Company N.L. And Arco Limited

Southwest Bairnsdale No. 1 Well was located about 15 miles west-south-west of Bairnsdale, in the Gippsland Basin of Victoria. The well was drilled by Reading and Bates (Australia) pty Ltd for Woodside (Lakes Entrance) Oil Company No Liability and Arco Limited, to total depth of 3926 feet. Drilling commenced on 8th January, 1963 and was completed on 14th February, 1963. A full programme of coring and logging was undertaken.
The objectives of the drilling operation were to obtain stratigraphic data, and to test the hydrocarbon potential of the pre-Tertiary sediments by a well favourably situated to intersect pinch-out zones in the expected Upper Devonian-Lower Carboniferous sequence occurring below a thin Tertiary cover.
The well achieved its objectives; Tertiary sediments were penetrated from surface to 1408 feet, Lower Carboniferous-Upper Davonian non-marine sediments to 3806 feet, and pre-Upper Devonian biotite granite to total depth at 3926 feet.
Middle Devonian marine sediments, which are exposed in the highlands 25 miles north of the well, were not encountered. Basal Tertiary gravels, although having good porosity and permeability, contained only freshwater. The Lower Carboniferous-Upper Devonian sandstones are well cemented and have very little porosity or permeability. No shows of hydrocarbons were found in the well.
One formation test was made over the interval 2522 to 2559 feet after a small quantity of gas was recorded by the gas detector. The test recovered only 120 feet of drilling mud anl;i the flowing pressures recorded were very low. The well was later plugged and abandoned as a dry hole.
The off-structure drilling operation at SouthwestBairnsdale No. 1 was subsidized under the Petroleum search Subsidy Act 1959-1961, from surface to total depth.

Fundamentals of airborne gamma-ray spectrometry

The interpretation of gamma-ray spectrometric data requires an understanding of the underlying physics of the method, and an insight into the data acquisition, system calibration, and data processing and presentation procedures.  The shape and intensity of a measured airborne gamma-ray spectrum is a complex function of many variables.  Source thickness, source diameter, the detector response, and the distance between the source and the detector all affect the measured spectrum.  The approach taken to calibration, therefore, is empirical.  The source and detector are viewed as a single system, and the response of this system to changes in aircraft height (to obtain attenuation coefficients) and sources of known geometry and concentration (to obtain sensitivity coefficients) is measured.  These empirically determined constants are, however, only valid for the source and source-detector geometry used in the calibration process.
