Presentation for MODSIM2013.

Presented at the Evolution and metallogenesis of the North Australian Craton Conference, 20-22 June 2006, Alice Springs. The Warumpi Province is an east-trending 1690 Ma - 1600 Ma terrane which extends for >500 km along the southwestern margin of the Arunta Region. It is interpreted to be an exotic terrane that accreted onto the southern margin of the North Australian Craton (NAC) at 1640 Ma (Scrimgeour et al 2005a). The evolution of the Warumpi Province from 1690 Ma to 350 Ma has been constrained through integrated lithological, structural and metamorphic mapping, geochemical and isotopic analysis, and geophysical interpretation (Scrimgeour et al 2005b). The Warumpi Province has been subdivided into three domains that have differing protolith ages and structural and metamorphic histories: the amphibolite facies Haasts Bluff Domain in the south and east, the granulite facies Yaya Domain in the north, and the greenschist facies Kintore Domain in the west. The Warumpi Province can be viewed as greenfields in terms of minerals exploration and has the potential to host a variety of mineralisation styles including base metals (BHT, VMS), IOCG, and diamonds. No modern mineral exploration has been undertaken within the Warumpi Province. <p>Related product:<a href="https://www.ga.gov.au/products/servlet/controller?event=GEOCAT_DETAILS&amp;catno=64764">Evolution and metallogenesis of the North Australian Craton Conference Abstracts</p>

Presented at the Evolution and metallogenesis of the North Australian Craton Conference, 20-22 June 2006, Alice Springs. The 2005 Tanami Seismic Collaborative Research Project produced four regional deep seismic reflection traverses, 05GA-T1 through 05GA-T4, totalling 724 line-km. Traverse 05GA-T1, a 354.3 km long northwest-southeast regional transect started in Western Australia and ended in the Northern Territory. It was located close to Tanami Gold's Bald Hills deposits and Newmont's Tanami and The Granites mine sites. This traverse provided cross-strike information on the geometry of the Coomarie and Frankania granite complexes as well as many of the region's fault systems. The traverse ended at the southern edge of the Willowra Gravity Ridge. The cross-traverses, 05GA-T2 (101.8 km long), 05GA-T3 (179.2 km long) and 05GA-T4 (84.4 km long) provide orthogonal three-dimensional control on the geometry of the region's main fault systems. The project objectives are to: - Image the geometry of the main faults; - Determine a deformation sequence for these faults; - Identify any through-going crustal structures; - Determine stratigraphic thicknesses of the Tanami Group and granite body geometries; - Determine relationships of the various stratigraphic packages to controlling structures; - Investigate the relationship of mineralised domains to crustal scale structures; - Identify Archaean basement and its relationship to the overlying Tanami Group stratigraphy; - Investigate the character of the Tanami-Arunta boundary. <p>Related product:<a href="https://www.ga.gov.au/products/servlet/controller?event=GEOCAT_DETAILS&amp;catno=64764">Evolution and metallogenesis of the North Australian Craton Conference Abstracts</p>

Australian Landscapes are prone to fire, from the Northern Savanna to the southern forests of Tasmania. Although fire is natural and is a vital management tool, fires are also a hazard to people and assets across Australia. Sentinel is a national fire hotspots detection and mapping system operated by Geoscience Australia. Sentinel was developed collaboratively by Geoscience Australia and CSIRO and has been operating since 2003. Hotspots are detected using satellite-based sensors monitoring all of Australia up to four times each day. The information is freely available to end-users through a web-site, as data feeds and down-loads. Sentinel has detected over 4 million hot-spots so far. In 2014 Geoscience Australia re-developed Sentinel including: - A more robust and maintainable 'backend' system, enabling quick and easy ingestion of new sources of hotspot data and fire related products - Improved user interface for the visualization of current hotspots and download of archived hotspots data - Separate access for emergency management users to ensure reliable access to hotspots data during major events - Improved interoperability, through reconsideration of the attributes used to describe a hotspot, anticipating the need for a standard approach to this problem
