Report on White's deposit, Rum Jungle, Northern Territory

White's Deposit, which is the original discovery at Rum Jungle, and on which exploration has been mainly concentrated, has so far proved to be the most important deposit in the area. It is situated 2.23 miles on a true bearing of 28 degrees from Rum Jungle Railway Siding and lies on the northern bank of the Finniss River (East Branch) halfway between Brown's Deposit and Dyson's Find. Following upon the favourable results obtained from diamond drilling and shaft sinking in 1950 work was continued at the deposit during 1951 and 1952. The development work and exploration activities are not yet completed, but available evidence has suggested a control of mineralization, which it is hoped will be substantiated by future field work. Geological and assay plans and sections of the mine workings have been prepared on a scale of 20 feet to an inch from theodolite and tape surveys and surface geological plans on a scale of 40 feet to an inch have been produced by plane table and telescopic aledade surveys. A description of the deposit based on results obtained to the end of 1952 is given in the following pages.

Radiometric Grid of Australia (Radmap) v4 2019 ratio thorium over potassium

The thorium over potassium grid is a derivative of the 2019 radiometric or gamma-ray grid of Australia. 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 are collected on airborne geophysical surveys conducted by Commonwealth, State and Northern Territory Governments and the private sector.
The 2019 thorium over potassium was derived by seamlessly merging over 600 airborne gamma-ray spectrometric surveys. The final grid has a cell size of about 100m (0.001 degrees) and is derived from the filtered thorium and potassium grids.

GSWA Hickman Crater Doserate 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. The terrestrial dose rate grid is derived as a linear combination of the filtered K, U and Th grids. A low pass filter is applied to this grid to generate the filtered terrestrial dose rate grid.
This GSWA Hickman Crater Doserate Grid Geodetic has a cell size of 5e-05 degrees (approximately 5m) and shows the terrestrial dose rate of the South Pilbara, Hickman Crater, WA, 2011.

Cobar P5009 EXT 6 reduced to pole fft 1st vertical derivative grid

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 Cobar P5009 EXT 6 reduced to pole fft 1st vertical derivative grid is the first vertical derivative of the TMI RTP grid of the Cobar Magnetic and Radiometric Survey, 2021 survey.
This grid has a cell size of 0.00039074 degrees (approximately 40m) , and given in units of nT per metre (nT/m).  The data used to produce the TMI grid was acquired in 2021 by the NSW Government, and consisted of 53617 line-kilometres of data at 200m line spacing and 60m terrain clearance. The data has had a variable reduction to the pole applied to centre the magnetic anomaly over the magnetised body. The VRTP processing followed a differential reduction to pole calculation up to 5th order polynomial. Magnetic inclination and declination were derived from the IGRF-11 geomagnetic reference model using a data representative date and elevation representative of the survey. A first vertical derivative was calculated by applying a fast Fourier transform (FFT) process to the TMI RTP grid of the Cobar Magnetic and Radiometric Survey, 2021 survey to produce this grid. This grid was calculated using an algorithm from the INTREPID Geophysics software package. This grid shows the magnetic response of subsurface features with contrasting magnetic susceptibilities. The grid can also be used to locate structural features such as dykes.

Groundwater resource management and community consultation - Blue Lake, South Australia

The Blue Lake is a high value groundwater resource in a high risk environment. The lake has several beneficial uses.  It is a water supply for the City of Mount Gambier.  It is the premier tourist attraction for the City, because of its picturesque setting within a volcanic crater and its habit of changing colour from a steel grey-green in winter to an intense blue in summer.  The lake also supports a considerable diversity of aquatic life, although individual numbers of any species are not abundant.  The City of Mount Gambier is located on the northern flank of the volcanic complex . The complex occurs within an unconfined karstic limestone aquifer, and the lake is a window into the groundwater.  Historical waste disposal practices have caused a number of point-source pollution plumes within the unconfined aquifer.  Sewage and septic tank effluent routinely reached the aquifer before a sewerage system was installed in the mid 1960s.  The effluent has polluted the groundwater beneath the city with nitrate.  Regional hydraulic gradients show that the city is located immediately upgradient of the lake.  Nitrogen levels in the lake have climbed to around 3.6 mg/L. There appears to be a relationship between extraction rate from the lake and nitrogen levels in the lake. Other pollutants are not evident in the lake.  The Engineering and Water Supply Department are developing a Management Plan for the Blue Lake and the surrounding groundwaters.  This Plan is being developed with the assistance of a small group from the community and with a broader community consultation program, with several benefits. These include community education about the issues and community ownership of the solutions.

Perth International Map of the World (IMW) 1:1 000 000 topographic map

The International Map of the World (IMW) series is no longer maintained, and printed copies of this map are no longer available. The Australian portion of the series consists of 49 maps. They were produced to an international specification using the R502 series at 1:250,000 scale as source material. Production commenced in 1926 and was completed in 1978. The maps were revised from time to time and the last reprint was undertaken in 2003. Each standard map sheet covers 4 degrees of latitude by 6 degrees of longitude and was produced using a Lambert Conformal Conic projection with 2 standard parallels. The series has recently been superseded by the 1:1 000 000 topographic map general reference.

Connecting diverse landslide inventories for improved landslide information in Australia

The evolution of the Australian Landslide Database (ALD) was driven by the need for a nationally consistent system of data collection in order to develop a sound knowledge base on landslide hazard and inform landslide mitigation strategies. The use of 'networked service-oriented interoperability' to connect disparate landslide inventories into a single 'virtual' national database, promotes a culture of working together and sharing data to ensure landslide information is easily accessible and discoverable to those who need it.
