Australia's Identified Mineral Resources 2009

Australia's Economic Demonstrated Resources (EDR) for the following 18 mineral commodities increased during 2008 - black coal, copper, gold, iron ore, lead, lithium, manganese ore, molybdenum, nickel, niobium, rare earth oxides, silver, tantalum, tungsten, uranium, vanadium, zinc and zircon. In the same period, EDR of nine commodities decreased - brown coal, cobalt, diamonds (gem and industrial), mineral sands (ilmenite and rutile), platinum group elements, shale oil and tin. EDR for antimony, bauxite, cadmium, magnesite, and phosphate rock remained at levels similar to those reported in 2007.
World ranking: Australia's EDR of brown coal, mineral sands (rutile and zircon), nickel, silver, uranium, zinc and lead remain the world's largest, while antimony, bauxite, black coal, copper, gold, industrial diamond, iron ore, ilmenite, lithium, manganese ore, niobium, tantalum and vanadium all rank in the top six worldwide.
Resource life: Ratios of accessible Economic Demonstrated Resources (AEDR) to current mine production provide indicative estimates of the resource life.  AEDR of most of Australia's major commodities can sustain current rates of mine production for many decades.  Resource life based on ore reserves is lower, reflecting a shorter term commercial outlook.
Over the decade 1997 to 2008 there has been a significant trend towards lower AEDR/production ratio for coal and iron ore, which was the nett result of major increases in production and reassessment of resources.
Commodities with resource life of less than 50 years are diamonds (about 10 years at current rates of production), manganese ore (20 years), gold (30 years), zinc (35 years) and lead (40 years). 
The severe world financial crisis in late 2008 highlighted the fact that a long resource life for a particular commodity is not a guarantee that such resources will continue to be exploited in Australia. In an increasingly globalised and competitive commodity market, multinational mining companies are continually in search of mineral deposits that will offer attractive returns on their investment. Such returns are influenced by the quality of the resources (grade and tonnage) as well as environmental, social and political factors, land access and even the location and scale of the competitor projects - individual mine projects in Australia will be ranked by multinational corporations against the investment returns from other deposits worldwide. 
Australia's continuing position as a premier mineral producer is dependent on continuing investment in exploration to locate high quality resources and/or to upgrade known deposits in order to make them competitive on the world market, and investment in beneficiation processes to improve metallurgical recoveries.
Australia's Identified Mineral Resources 2009 provides information on and analysis of mineral exploration expenditures in Australia for the calendar year 2008. Trends in expenditure are presented and discussed.

GA Landsat 7 ETM+ Analysis Ready Data Collection 3

BACKGROUND

The United States Geological Survey's (USGS) Landsat satellite program has been capturing images of the Australian continent for more than 30 years. This data is highly useful for land and coastal mapping studies. 
In particular, the light reflected from the Earth’s surface (surface reflectance) is important for monitoring environmental resources – such as agricultural production and mining activities – over time. 
We need to make accurate comparisons of imagery acquired at different times, seasons and geographic locations. However, inconsistencies can arise due to variations in atmospheric conditions, sun position, sensor view angle, surface slope and surface aspect. These need to be reduced or removed to ensure the data is consistent and can be compared over time.  
&nbsp
WHAT THIS PRODUCT OFFERS

GA Landsat 7 ETM+ Analysis Ready Data Collection 3 takes Landsat 7 Enhanced Thematic Mapper (ETM+) imagery captured over the Australian continent and corrects for inconsistencies across land and coastal fringes. The result is accurate and standardised surface reflectance data, which is instrumental in identifying and quantifying environmental change. 

The ETM+ instrument is a fixed ‘whisk broom’, eight-band, multispectral scanning radiometer capable of providing high-resolution imaging information of the Earth’s surface. It is an enhanced version of the Thematic Mapper (TM) sensor. 

This product is a single, cohesive Analysis Ready Data (ARD) package, which allows you to analyse surface reflectance data as is, without the need to apply additional corrections. 

It contains three sub-products that provide corrections or attribution information:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1) GA Landsat 7 ETM+ NBAR Collection 3 
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2) GA Landsat 7 ETM+ NBART Collection 3
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3) GA Landsat 7 ETM+ OA Collection 3

The resolution is a 30 m grid based on the USGS Landsat Collection 1 archive.

Cobar P5009 EXT 3 reduced to pole grid

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 magnetic grid has a cell size of 0.00039074 degrees (approximately 40m).The data are in nanoTesla (or nT). The data used to produce this grid was acquired in 2021 by the NSW Government, and consisted of 53617 line-kilometres of data at 200m line spacing and 60m terrain clearance. The data has had a variable reduction to the pole applied to centre the magnetic anomaly over the magnetised body. The VRTP processing followed a differential reduction to pole calculation up to 5th order polynomial. Magnetic inclination and declination were derived from the IGRF-11 geomagnetic reference model using a data representative date and elevation representative of the survey.

Proterozoic mafic-ultramafic intrusions in the Arunta Region, central Australia.  Part 2: event chronology and regional correlations

The Arunta Region of central Australia exposes the southern margin of the North Australian Craton and contains a record of multiple Proterozoic craton margin processes over a 1500 million year period.  The place of mafic magmatism in this evolution is constrained by SHRIMP U-Pb dating of zircon, which is a primary igneous phase in the evolved sectors of mafic-ultramafic plutons across the region.  The earliest mafic magmatism was in the 1800-1810 Ma Stafford Event, which is the first thermal system recognised in the region.  Mafic plutons from this event may correlate with other expressions of mafic magmatism northwards within the craton.  A second episode of mafic magmatism is recognised at 1770-1790 Ma (Yambah Event) and lacks correlatives elsewhere in the craton, as do all subsequent Arunta Region mafic magmatic events.  Zircon overgrowths in Stafford- and Yambah-age plutons record conversion of these early intrusions into granulite grade metamorphic complexes during the Strangways Event, a regionally pervasive metamorphic system whose termination at ca. 1690 Ma coincided with local intrusion of dolerite dykes.  Gabbro intrusion at ca. 1640 Ma in the Liebig Event is restricted within the Warumpi Province which is recognised as a separate terrane in the south of the region.   There is no record of a mafic magmatic component to the ca. 1590 Ma Chewings event and most of the earlier intrusions do not record metamorphism at this time.  Later mafic magmatic systems include pyroxenite intruded as part of the Mordor Complex at ca 1130 Ma (Teapot Event); and both erupted and intruded basaltic magma are components of the fault-bound Irindina Province which experienced high grade metamorphism during the Ordovician (Larapinta Event).  The dating establishes that each of these craton margin event systems includes a mafic magmatic component, which suggests that repeated extensional systems are an important component of the tectonic evolution.

Capel and Faust Basins - New Information from the Offshore Frontier Between Australia, New Zealand and New Caledonia

New geophysical and geological datasets have been acquired in water depths of 1300-2500m from the Capel and Faust basins located some 800 km east of Brisbane (Figure 1). Between December 2006 and January 2007 Geoscience Australia acquired ~6000 km of industry standard 2D seismic data using an 8 km solid streamer.  The survey identified numerous depocentres, some up to 150 km in length and 40 km in width with up to 7 km of sediment fill. Initial interpretation has identified a potential pre-rift succession, three syn-rift phases (clastic/volcanic), and two post-rift carbonate packages. Episodes of post-rift igneous activity are also apparent. Possible correlations with the Capricorn, Great South and/or deepwater Taranaki basins are suggested.
In late 2007 the RV Tangaroa completed a marine reconnaissance survey of the Capel and Faust basins. Geophysical datasets acquired on this survey included gravity, magnetics, multibeam sonar, and sub-bottom profiler data. An accompanying seafloor sampling program acquired geological and biological samples from potential seepage sites and representative areas of the sea floor, to search for indications of active petroleum systems and to document marine biodiversity and habitats.  These datasets are designed to better define the region's petroleum prospectivity and inform marine and environmental planning decisions.   
The multibeam sonar revealed seafloor features that appear to reflect the underlying basin structure, such as fault-related slumps. The gravity and magnetic coverages are expected to significantly improve the delineation of depocentre boundaries. Seafloor sampling and camera footages provided information on the substrate composition and potential fluid escape sites. Current work involves the initial interpretation of these datasets and their integration to define the rift basin architecture and tectonostratigraphic history to better understand the region's petroleum prospectivity.
