Geological map of Western Australia 1:2 500 000, 2015
by Martin, DMcB, Hocking, RM, Riganti, A, and Tyler, IM
This map is the culmination of 15 years of work that has profoundly reshaped how GSWA delivers geoscience data and products. The map is the first to be compiled entirely by digital means, with spatial accuracy inherited from and reflecting larger scale spatially accurate geological mapping.
The map will be officially launched by the Minister and hard copy maps will be available free of charge.
Geological interpretation of the West Musgrave Province
by Howard, H, Smithies, RH, Quentin De Gromard, R, Evins, P, and Werner, M
This 1:250 000-scale map is a geological interpretation of the GSWA project area in the west Musgrave Province. The eastern part of the region features the Mesoproterozoic granites, formed and deformed during two major events — the 1345–1293 Ma Mount West Orogeny and the 1220–1150 Ma Musgrave Orogeny. The failed intracontinental Ngaanyatjarra Rift produced voluminous mafic and felsic rocks during the 1085–1040 Ma Giles Event. The intrusive rocks of the Warakurna Supersuite are present throughout this region and in the west; the outcrop is dominated by extensive volcanic, volcaniclastic and sedimentary sequences that were deposited into the Bentley Basin.
Report 156 Integrated spectral mapping of precious and base metal related mineral footprints, Nanjilgardy Fault, Western Australia
by Wells, M, Laukamp, C, and Hancock, EA
The Nanjilgardy Fault juxtaposes an inlier of the Proterozoic Shingle Creek Group and older metasedimentary units against the Wyloo Group at the Mt Olympus gold deposit, Ashburton Province. This fault and related structures are possibly deep-rooted suture zones that may have provided conduits for mineralizing fluids and, hence, define a potentially highly prospective, northwest-southeast trending corridor for gold mineralization.
Mineralogical variations associated with large and small-scale structures can be defined by combining proximally derived hyperspectral HyLogging-3 and regolith geochemistry data with remotely sensed AEM and ASTER data, and, therefore, could be used to develop 3D mineral maps from the deposit scale through to surface expression at the regional scale. Hence, this would help to recognize the mineral footprints signature of concealed metalliferous mineralization.
Record 2015/14 Geological map of Western Australia 14th edition: Explanatory Notes
by Martin, DMcB, Hocking, RM, Riganti, A, and Tyler, IM
The State geological map is a flagship product of GSWA, produced on average about once per decade. The 2015 edition is the fourteenth in the series, and the first to be compiled entirely digitally and released simultaneously as a printed map and complementary digital data layers. These explanatory notes provide details on the compilation and style of presentation of both the printed map and digital data, as well as a high-level summary of the geology of the State as depicted on the map.
Record 2016/3 Integrated Exploration Platform (IEP v2.5): An innovative visual analytics platform
by Wong, JC, Holden, E-J, Kovesi, P, Gessner, K, and Murdie, RE
Mineral Exploration relies heavily on the interpretation of increasingly varied and complex geoscience datasets. In an Australian Research Council-funded project the Centre for Exploration Targeting at UWA and GSWA have developed add-in tools for the ESRI ArcGIS platform. The Integrated Exploration Platform (IEP) uses innovative interactive visualization and image-analysis methods in two sets of visualization tools that are aimed at assisting the interpretation of different datasets, and at improving interpretation confidence. The IEP will be launched at the GSWA Open Day 2016 and will be freely available to Western Australia explorers on the web.
Mapping Western Australia — State geological maps 1894–2015
by Riganti, A, Johnston, J, Hocking, RM, and Martin, DMcB
The 2015 Geological Map of Western Australia (otherwise known as the 2015 State map) at a scale of 1:2 500 000 is the latest in a series that stretches back to 1894. These maps come in all forms, sizes and colours as geological knowledge, accuracy and detail is continually enhanced. Improvements in cartographic techniques run in parallel with the geological changes. The 2015 State map was compiled as a ‘roll-up’ from Statewide digital datasets assembled at larger scale — the first time that a Western Australian State map has been compiled in this way, and one of the first such smart maps in the world, with searchable data layers that underlay the digital version of the map itself. This collection of Western Australia’s State geological maps is a tribute to the passion of the geologists who, since the 19th century, have journeyed to and mapped almost every inch of this vast and richly endowed region.
Everythere Rottnest Island — an app showcasing geotourism locations
Everythere is an amazing app which allows users to find attractions, tours and walks in their location. The app finds users based upon their GPS coordinates or proximity to its iBeacons. Did you know that as well as sun, sand, and surf, the little rocky island of Rottnest has some geological features of international significance? GSWA has published a pamphlet on some of the world-class geology found on Rottnest. Using the pamphlet, you can visit nine geological sites round the island from West End (in the far west) to The Basin (just round the corner from Thomson Bay). GSWA has partnered with the Everythere app using its Rottnest Island brochure to allow geotourists to find out geological information when they are riding around the island.
GSWA Open Day 2016 will see the release of processed images for the Eucla–Gawler deep crustal seismic reflection line, which is part of a collaboration between Geoscience Australia (GA), the Geological Survey of Western Australia (GSWA), the Geological Survey of South Australia and AuScope Earth Imaging (part of the National Collaborative Research Infrastructure Strategy). This 870-kilometre survey along the Trans-Australian Railway was conducted across Western Australia’s Nullarbor region during 2013 and 2014. The Eucla–Gawler region is a major geological frontier, buried by extensive sedimentary cover associated with the Eucla Basin (Nullarbor Plain). The region lies between two of the most prospective geological regions in the world, Western Australia’s Yilgarn Craton to the west and the Gawler Craton in South Australia to the east.
