  • This map shows copper locations by Event, Type and Status. It also shows copper regions and copper occurrences that fall within these regions. The map includes a Time-Space-Event chart, and pie charts.

  • Australia crustal elements map based on the distribution of geophysical domains

  • The first edition ACE - Australian Continental Elements dataset is a GIS representation of the lithosphere fabrics of the Australian plate, interpreted from linear features and associated discontinuities in the gravity anomaly map of continental Australia (Bacchin et al., 2008; Nakamura et al., 2011) and the global marine gravity dataset compiled from satellite altimetry (Sandwell & Smith, 2009). It should be used in context with these input data sources, at scales no more detailed than the nominal scale of 1:5 000 000.

  • SUMMARY Geoscience Australia operates and maintains a state-of-the-art network of stations and sophisticated instrumentation that monitors natural and anthropogenic (human-made) hazards in Australia and around the globe through its Geophysical Network Section. The key responsibilities for the Geophysical Network Section are to: operate and maintain the Australian National Seismic Network (ANSN) and Urban Monitoring (UM) networks; operate and maintain Australian Comprehensive Nuclear-Test-Ban Treaty (CTBT) seismic, hydro-acoustic and infrasound technologies, as part of Australia's commitment to support monitoring of worldwide nuclear testing; operate and maintain a national network of geomagnetic observatories which forms a part of a global observatory network; provide technical expertise and advice to Geoscience Australia projects, such as the National Geospatial Reference Systems Risk Research Group and the JATWS (Joint Australian Tsunami Warning System); and, provide technical and operational support to the Risk Research Group for significant Australian earthquake events and aftershock deployment studies. Geophysical data archives are stored on-site and can be freely downloaded from GA or international data centres. Seismic data can be accessed at GA and Incorporated Research Institutions for Seismology (IRIS) and geomagnetic data at INTERMAGNET. Seismic data from Geoscience Australia's Geophysical Networks feeds into important hazard maps including the probabilistic national earthquake hazard map and the probabilistic Tsunami hazard map. Geomagnetic data feeds into the International Geomagnetic Reference Field and has been used to develop the first 3-D conductivity map of Australia. Key words: Geophysical Networks, geomagnetism, earthquake, tsunami, nuclear monitoring
