Constraining Surface Deformation Predictions from Coal Seam Gas Extraction

This Record describes techniques which can be used to predict surface deformation caused by natural or anthropogenic subsurface fluid changes. Using predictive (forward) models, simulations have been developed to estimate the range of surface deformation caused by the Coal Seam Gas (CSG) extraction operations in the Surat Basin. 
The objectives of this research were to:
-   Develop a predictive model that enables Geoscience Australia to estimate the magnitude and areal extent of surface deformation caused by natural or anthropogenic fluid activities.
-   Report the capability, accuracy and limitations of the predictive model.
-   Apply the predictive model to Coal Seam Gas operations in the Surat Basin, Queensland. 
-   Describe the monitoring techniques capable of measuring subsurface fluid changes
-   Discuss how geodetic data can be used to constrain the poroelastic properties of reservoirs.

GSQ Cloncurry 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 GSQ Cloncurry DoseRate grid geodetic has a cell size of 0.00018 degrees (approximately 19m) and shows the terrestrial dose rate of the Isa Region Airborne Magnetic Radiometric and DEM Survey, QLD, 2017. The data used to produce this grid was acquired in 2017 by the QLD Government, and consisted of 113387 line-kilometres of data at a line spacing between 50m and 100m, and 50m terrain clearance.

SHRIMP U-Pb isotopic results, GSWA Harvey 1, Western Australia

This Record contains nine detrital zircon U-Pb geochronological datasets (outlined in Table 1.1) obtained via Sensitive High-Resolution Ion Microprobe (SHRIMP) from nine sedimentary samples obtained from the Geological Survey of Western Australia (GSWA) Harvey 1 well. Analysis was supported by the GSWA and Royalties for Regions Exploration Incentive Scheme (EIS). GSWA Harvey 1 was drilled in the southern onshore Perth Basin, Western Australia, on the ‘Harvey Ridge’ structural feature (Millar and Reeve, 2014). The aim of the study was to provide insights into the potential provenance of sedimentary rocks of the southern Perth Basin.
This record provides detailed results for each sample individually, including a description of the target mineral for geochronology, the relevant analytical data and a brief geochronological interpretation.
The Leederville Formation sample has a 238U/206Pb maximum depositional age of 134 ± 3 Ma (2σ), which is consistent with the Early Cretaceous (Hauterivian–Aptian), biostratigraphically determined depositional age.
Three Eneabba Formation samples yield individual 238U/206Pb maximum depositional ages, from shallowest to deepest, of 514 ± 15 Ma (2σ), 515 ± 11 Ma (2σ), and 505 ± 23 Ma (2σ), respectively. These ages are considerably older than the biostratigraphically determined Early Jurassic depositional age.
Four Lesueur Sandstone samples yield individual 238U/206Pb maximum depositional ages, from shallowest to deepest, of 517 ± 14 Ma (2σ), 527 ± 9 Ma (2σ), 513 ± 24 Ma (95% confidence), and 513 ± 14 Ma (2σ), respectively. These ages are considerably older than the biostratigraphically determined Late Triassic depositional age.
The single Sabina Sandstone sample has a 238U/206Pb maximum depositional age of 537 ± 9 Ma (2σ), which is considerably older than the biostratigraphically determined Early Triassic depositional age.

2014 Mount Stromlo Geodetic Observatory Co-Location Local Tie Survey Technical Report

The integrity and strength of multi-technique terrestrial reference frames, such as realisations of the International Terrestrial Reference Frame (ITRF), depend on the precisely measured and expressed local-tie connections between space geodetic observing systems at co-located observatories. Australia has several observatories which together host the full variety of space geodetic observation techniques, including Global Navigation Satellites Systems (GNSS), Very Long Baseline Interferometry (VLBI), Satellite Laser Ranging (SLR) and Doppler Orbitography and Radiopositioning Integrated by Satellite (DORIS) beacons.

This report documents the technical aspects of the local tie survey completed at the Mount Stromlo observatory, in Canberra in 2014. The aim of the survey was to precisely measure the local terrestrial connections between the space-based geodetic observing systems co-located at the observatory, which include 3 International GNSS Service (IGS) stations, SLR and DORIS infrastructure. In particular, this report documents the indirect measurement of the SLR invariant reference point. Geoscience Australia has routinely performed classical terrestrial surveys at Mount Stromlo, including surveys in 1999, 2002 and 2003 (post-fire). A high precision survey was conducted between the survey pillars surrounding the SLR observatory. These survey pillars were monitored to ensure their stability as part of a consistent, stable terrestrial network from which local tie connections were made to the SLR and other observing systems. The relationship between points of interest included the millimetre level accurate connections and their associated variance covariance matrix.

Geology of the Cambridge Gulf

These data are a digital representation of information depicted on the printed map of the Cambridge Gulf 1:250 000 Geological Series produced by AGSO and the Geological Survey of Western Australia (GSWA) in 1971.
Data present include geological polygons (litho-stratigraphic units), linear structural features (faults, dykes, folds, trends, lineaments etc), and point features (mines, structural points etc). Polygons have a range of attributes extracted from each individual map including unit name, age and lithological description, while lines and points are feature coded according to the AGSO publication 'Symbols Used On Geological Maps' (BMR 1989). A standard look-up table of AGSO geological codes and associated descriptions is available (see ADDITIONAL METADATA).
The data has gradually evolved from elementary CAD quality data into its present topologically structured GIS format, and hence has many imperfections and inconsistencies. Data has undergone rigorous validation and testing that includes over 80 different tests. See ADDITIONAL METADATA for more information on the data standards used.

GSNSW Eromanga-Thompson magnetic 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 GSNSW Eromanga-Thompson magnetic grid geodetic has a cell size of 0.00077 degrees (approximately 80m). The units are in nanoTesla (or nT).

A Methodology for Post-Mainshock Probabilistic Assessment of Building Collapse Risk

This paper presents a methodology for post-earthquake probabilistic risk
(of damage) assessment that we propose in order to develop a computational tool for
automatic or semi-automatic assessment. The methodology utilizes the same so-called
risk integral which can be used for pre-earthquake probabilistic assessment. The risk
integral couples (i) ground motion hazard information for the location of a structure of
interest with (ii) knowledge of the fragility of the structure with respect to potential
ground motion intensities. In the proposed post-mainshock methodology, the ground
motion hazard component of the risk integral is adapted to account for aftershocks which
are deliberately excluded from typical pre-earthquake hazard assessments and which
decrease in frequency with the time elapsed since the mainshock. Correspondingly, the
structural fragility component is adapted to account for any damage caused by the
mainshock, as well as any uncertainty in the extent of this damage. The result of the
adapted risk integral is a fully-probabilistic quantification of post-mainshock seismic risk
that can inform emergency response mobilization, inspection prioritization, and reoccupancy
decisions.
