Cobar 1:250 000 topographic map

This map is part of the series that covers the whole of Australia at a scale of 1:250 000 (1cm on a map represents 2.5 km on the ground) and comprises 513 maps. This is the largest scale at which published topographic maps cover the entire continent. Each standard map covers an area of 1.5 degrees longitude by 1 degree latitude or about 150 kilometres from east to west and 110 kilometres from north to south. There are about 50 special maps in the series and these maps cover a non-standard area. Typically, where a map produced on standard sheet lines is largely ocean it is combined with its landward neighbour. These maps contain natural and constructed features including road and rail infrastructure, vegetation, hydrography, contours (interval 50m), localities and some administrative boundaries. The topographic map and data index shows coverage of the sheets. Product Specifications Coverage: The series covers the whole of Australia with 513 maps. Currency: Ranges from 1995 to 2009. 95% of maps have a reliability date of 1994 or later. Coordinates: Geographical and either AMG or MGA (post-1993) Datum: AGD66, GDA94, AHD. Projection: Universal Traverse Mercator (UTM) Medium: Paper, flat and folded copies.

Papua New Guinea Field Notebooks

This is the collection level record for the N.H. (Doc) Fisher Geoscience Library's 219 Papua New Guinea geological field notebooks.  Digitised copies of the notebooks are being transcribed and validated by a dedicated team of volunteers from around Australia via the Australian Museum's DigiVol Citizen Science transcription platform. This project is being managed by Information Systems and Services Librarian Robert Blyth.
The PNG field notebooks contain the geological observations recorded by Bureau of Mineral Resources and AGSO geologists during their field trips to pre- and post-Independence Papua New Guinea from the 1950s to the 1990s.  Individual records for these notebooks are not yet available in eCat, but are in the Library's online catalogue (go to https://geoscienceaustralia.intersearch.com.au, click on Lists at top left and select PNG Field Notebooks).  Processing of the image and transcription files is continuing, with the aim of making these available in eCat when this work is complete.  The original field notebooks are held at the N.H. (Doc) Fisher Geoscience Library at Geoscience Australia, Canberra.

Stromatolites of Hamelin Pool

Hamelin Pool and Lharidon Bight are separated from the open waters of Shark Bay by the Faure Sill - a wall of sand built by sea-grass banks. High evaporation rates increase the salinity of water in Hamelin Pool. Channels across the sill allow tidal exchange of surface waters, but water cannot be completely flushed from the shallow embayment. 
Microbes flourish because their competitors and predators are controlled by the low nutrient levels and high salinities (about twice that of normal sea water). Stromatelites grow around the margins of Hamelin Pool - in waters less than four metres deep - where sufficient concentrations of ions exist to promote calcification. As no rivers flow into Hamelin Pool, these slow growing structures are not swamped by sediment

The Nunyerrie chrysotile deposits, West Pilbara goldfield, Western Australia

The Nunyerrie Asbestos Deposits are associated with a remnant of metamorphosed ultrabasic rocks in granite country, which is part of a group of Pre-Cambrian rocks of Archaean age. The ultrabasics form an east northeast  trending ridge about 1 mile long and 250 feet average width, which rises to a maximum elevation of 300 feet above the general level of the surrounding country. The belt of ultrabasics is highly sheared and jointed and consists chiefly of serpentines, but talcose rocks, chlorite schists, authophyllite rock and what appear to be hydro-biotite schists also occur. The ultrabasics have an intrusive junction with the surrounding granite rocks, and they are intruded by quartz veins and granitic dykes. The deposits were investigated by the author. This report gives an overview of the deposits. Workings, production figures, reserves, grades, and prices are described.

GSQ Mary Kathleen ReducedToPole 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 magnetic grid has a cell size of 9e-05 degrees (approximately 10m).The data are in nanoTesla (or nT). The data used to produce this grid was acquired in 2017 by the QLD Government, and consisted of 113387 line-kilometres of data at line spacing between 50m and 100m, and 50m 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.

The hydrothermal environment

Hydrothermal mineral deposits are the products of crustal geochemical processes that extract metals from source regions and concentrate them at depositional sites. These processes and the regions in which they occur constitute mineral systems.  Processes that occur within source regions define the characteristics (e.g. temperature, pressure, pH, salinity, redox, sulphur content) of hydrothermal fluids, which, in turn, determine the metal carrying capacity of the fluid. Mineral deposits that contain Cu, Zn, Pb, Ag and/or Au can be classified into three general groupings based on metal assemblages: (1) Zn-Pb-AgÂ±Au , (2) CuÂ±Au , and (3) AuÂ±Ag. These groupings are predicted from fluid characteristics and the solubility of metals in the fluids. The hydrothermal geochemistry of Sn, W, U and Mo is not considered in this discussion.  Mineral deposit diversity results from the complex interplay of processes in source regions and depositional sites. First-order processes that occur in source regions include devolatilisation and degassing, circulation of surficial fluids, and expulsion of connate fluids. These and second-order processes such as SO2 disproportionation result in hydrothermal fluids with diverse temperatures, acidities, salinities, redox conditions, and, hence, metal-carrying capacities. Many of the processes in the source region are directly or indirectly linked to geological characteristics of the source region, such as granitoid type and basinal lithology.  Three first-order depositional processes cause metal deposition: phase separation, reaction with host rocks , and mixing with ambient fluids. The efficiency of metal deposition depends critically on the steepness of chemical gradients in the depositional environment. The interplay of source and depositional processes produces the observed diversity of mineral deposits, and placing these processes in a mineral system framework provides a powerful tool for understanding and, potentially, for discovering mineral deposits.
