  • This map is part of a series which comprises 50 maps which covers the whole of Australia at a scale of 1:1 000 000 (1cm on a map represents 10km on the ground). Each standard map covers an area of 6 degrees longitude by 4 degrees latitude or about 590 kilometres east to west and about 440 kilometres from north to south. These maps depict natural and constructed features including transport infrastructure (roads, railway airports), hydrography, contours, hypsometric and bathymetric layers, localities and some administrative boundaries, making this a useful general reference map.

  • 5 maps showing the offshore petroleum blocks in the Shared Area of the Perth Treaty. Also supplied were 4 Excel spreadsheets containing the listing of the blocks within the Perth Treaty. Requested by NOPTA 5th December 2012. Supplied as DRAFT in December, resubmitted without draft & new title on 12th February 2013 to RET & DFAT. LOSAMBA register 674.

  • Homogeneity Tests for a Rotary Sample Divider Two rock types, a coarse-grained granite and a finer-grained volcanic rock, were used to test a Rotary Sample Divider attached to a Rocklabs Boyd Crusher for homogeneity. Approximately 3kg of each rock type were broken down by a jaw crusher, and then processed through a Boyd Crusher with splits taken using the attached rotary sample divider. The formula 10/(100-(10*n))-where n=the number of the split-was used to process the entire sample, i.e., 10% of the first split was taken and remainder returned to the Boyd crusher; 11% of the second split taken and remainder returned to the crusher; 12.5% of the 3rd one taken and remainder returned to the Boyd crusher etc., until all the sample was used and there were 10 roughly equal splits. Each split was halved and each half pulverised for 3 minutes in a Tungsten Carbide ring mill for 3 minutes. Pressed powder pellets and Lithium Borate glasses were made and analysed using a PW2404 XRF spectrometer. Results of major and trace element analysis shows that there is no apparent bias between either individual splits or from the first split to the last split, indicating homogeneity was achieved using the rotary sample divider.

  • The Queen Charlotte Fault (QCF) off western Canada is the northern equivalent to the San Andreas Pacific - America boundary. Geomorphology and surface processes associated with the QCF system have been revealed in unprecedented detail by recent seabed mapping surveys carried out by the Canadian Hydrographic Service and the Geological Survey of Canada.

  • These datasets cover approximately 5030 sq km over all of the Scenic Rim Regional Council and were captured as part of the 2011 Scenic Rim LiDAR project. This project, undertaken by Terranean Mapping Technologies on behalf of the Queensland Government captured highly accurate elevation data using LiDAR technology. Available dataset formats (in 1 kilometre tiles) are: - Classified las (LiDAR Data Exchange Format where strikes are classified as ground, vegetation or building) - 1 metre Digital Elevation Model (DEM) in ASCII xyz - 1 metre Digital Elevation Model (DEM) in ESRI ASCII grid - 1 metre Digital Elevation Model (DEM) in ESRI GRID grid - 0.25 metre contours in ESRI Shape

  • This report presents new Sensitive High Resolution Ion Microprobe (SHRIMP) U-Pb zircon results (Table i) for 32 igneous and 2 metamorphic rocks, mainly from the Bowen region of north Queensland. Three samples are of granites from the northern New England Batholith in southern Queensland, and one granite sample is from the Eulo Ridge (Thomson Orogen) in southwestern Queensland. The work was carried out under the auspices of the National Geoscience Agreement (NGA) between Geoscience Australia and the Geological Survey of Queensland.

  • An application dated 20 November 2012 for verification of a reference standard of measurement under Regulation 12 of the National Measurement Regulations 1999 was received from the Caval Ridge Mine of RPS Australia East Pty Ltd in Queensland for verification of GDA94 position on their owned or managed station monument. This report documents the processing and analysis of GPS data observed by the Caval Ridge Mine during a 7-day period from 11 November to 17 November 2012 (day of year 316 to 322) for the station CAVL to satisfy the position verification requirements.

  • For well over a decade GPS time series have been used as an effective way of densifying a reference frame. During this period numerous advances have been made in the analysis and modelling techniques applied to GPS observations. This has seen GPS time series improve by almost an order of magnitude in accuracy, and has allowed even more challenging applications of GPS time series analysis to be investigated such as glacial isostasy, elastic deformation of the earth's crust due to atmospheric loading and atmospheric tomography. Despite numerous improvements in the GPS analysis technique to handle different error sources there still remains significant long term site-specific biases. The biases are often caused by local multi-path effects and/or near-field antenna phenomena and have an adverse impact on the signal being analysed. Typically the largest effect is seen in the height component or the scale of the reference frame determined by the GPS network. Correction of these site-specific systematic errors can not only remove biases, but will also reduce the phase residual noise level, thus providing a better resolution to distinguish the signal of interest. We will present a technique to detect, and model for long term systematic errors by using one-way phase residuals obtained from a post-processed GPS network. We will then assess the impact of applying these derived individual site models into a re-processed solution for the purposes of reference frame determination at the Regional and Global level. We will also asses the performance of these derived site-specific models for real-time solutions.

  • This report is a summary of findings by Geoscience Australia in relation to the project aim and is accompanied by additional outputs on: 1) the hydrogeology of Timor-Leste; 2) groundwater monitoring and sampling guidelines; 3) geophysical survey of three case study areas; 4) GIS methodology training guide to reproduce the outputs of this project; and 5) catalogue of datasets and data records. Training and workshops were carried out in Timor-Leste on the use of monitoring tools and the analysis of groundwater information. This project has developed key resources and tools to underpin the effective assessment, monitoring and management of groundwater resources in a changing climate.
