Great Artesian Basin - Cadna-owie Hooray Aquifer - Alkalinity

Data used to produce the predicted Alkalinity map for the Cadna-owie - Hooray Aquifer in the Hydrogeological Atlas of the Great Artesian Basin (Ransley et.al., 2015).
There are four layers in the Cadna-owie - Hooray Aquifer Alkalinity map data
A. Location of hydrochemistry samples (Point data, Shapefile)
B. Predicted Concentration (Filled contours , Shapefile)
C. Predicted Concentration Contours (Contours, Shapefile)
D. Prediction Standard Error (Filled contours , Shapefile)
The predicted values provide a regional based estimate and may be associated with considerable error. It is recommended that the predicted values are read together with the predicted error map, which provides an estimate of the absolute standard error associated with the predicted values at any point within the map.
The predicted standard error map provides an absolute standard error associated with the predicted values at any point within the map. Please note this is not a relative error map and the concentration of a parameter needs to be considered when interpreting the map. Predicted standard error values are low where the concentration is low and there is a high density of samples. Predicted standard errors values can be high where the concentration is high and there is moderate variability between nearby samples or where there is a paucity of data.
Concentrations are Alkalinity as CaCO3  mg/L.
Coordinate system is Lambert conformal conic GDA 1994, with central meridian 134 degrees longitude, standard parallels at -18 and -36 degrees latitude.
The Cadna-owie - Hooray Aquifer Alkalinity map is one of 14 hydrochemistry maps for the Cadna-owie - Hooray Aquifer and 24 hydrochemistry maps in the Hydrogeological Atlas of the Great Artesian Basin (Ransley et.al., 2014).

1 second SRTM Level 2 Derived Digital Surface Model v1.0

The 1 second SRTM derived DSM Version 1.0 is a 1 arc second (~30m) gridded digital surface model (DSM) that represents ground surface topography as well as features above the ground such as vegetation and man-made structures. The dataset was derived from the Shuttle Radar Topography Mission (SRTM) data acquired in February 2000, supported by the GEODATA 9 second DEM in void areas and the SRTM Water Body Data. Stripes and voids have been removed from the 1 second SRTM data to provide an enhanced and complete DSM for Australia and near-shore islands. 
This 1 second DSM forms the source for the 1 second DEM with vegetation offsets removed (ANZCW0703013355) and for smoothed and drainage enforced versions that are expected to be released in 2010.  The grid spacing is 1 second in longitude and latitude (approximately 30 metres).

New central Gawler gold HyLogger results - Preliminary results from the Tunkillia region, Central Gawler Gold Prospect, South Australia

The HyLogger hyperspectral core-mapping instrument, developed by CSIRO's Mineral Mapping Technologies Group (MMTG), can log up to 1000 m of core per day (more for chips) and has automated core tray handling, digital imaging and spectral scanning and specialised mineral identification software for rapid logging capability. The Central Gawler Gold Province HyLogger project is a collaborative undertaking between the collaborators/developers: CSIRO MMTG, Primary Industries and Resources South Australia (PIRSA) / Cooperative Research Centre for Landscape Environments and Mineral Exploration (CRC LEME) and Geoscience Australia. The Tunkillia prospect, part of the Central Gawler Gold Province, is located some 250 km South of Coober Pedy, and is a regolith-dominated landscape with up to 300m of cover. The area delineated as a de-magnetised zone by earlier studies, was extensively drilled with Diamond and RC drilling. Selected diamond holes from Tunkillia were selected for this HyLogger investigation.
At Tunkillia, high gold shows some correlation with white mica composition (phengite-muscovite), as well as mica crystallinity and spectral absorption feature wavelength shifts, possibly representing an increasing in acidity due to mixing of metamorphic muscovite and hydrothermal fluid in the altered granitic host rocks. Alteration occurring in mafic dykes, are well delineated by chlorite-carbonate minerals which can be easily mapped. Gold is predominantly confined to a granitic host, high gold in mafic rocks appears to occur in nearly all cases on margins / fracture zones between the dyke and the host rock.
This talk was presented at the Workshop on iron oxide copper-gold systems of the Gawler Craton, held at the AMF Centre, Adelaide on 24 February, 2006.

AUSGeoid98 v.1.0 data files: Lincoln (si53-11)

AUSGeoid98 data files contain a 2 minute grid of AUSGeoid98 data covering the Australian region, which you can use to interpolate geoid-ellipsoid separations for the positions required.You can use your own interpolation software, or you can use Geoscience Australia's Windows Interpolation software (Winter). The data files are text files in a standard format that cover the same area as standard topographic map areas. Files covering both 1:250,000 (approximately 100 x 150 km) and 1:1,000,000 (approximately 400 x 600 km) map areas are available. There is a 4 minute overlap on all sides of each area. Data format: AUSGeoid98 data files have a header record at the start of each file, to distinguish them from the superseded AUSGeoid93 data files. AUSGeoid98 data files show the geoid-ellipsoid separation to 3 decimal places, while the superseded AUSGeoid93 data files showed only 2 decimal places. AUSGeoid98 deflections of the vertical were computed from the geoid-ellipsoid separation surface, while the AUSGeoid93 deflections of the vertical were computed from OSU91A.

Flinders Island, Tas, 1987 (P524), magnetic line data, AWAGS levelled

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.
 These line dataset from the Flinders Island, Tas, 1987 survey were acquired in 1987 by the TAS Government, and consisted of 3445 line-kilometres of data at 1500m line spacing and 150m terrain clearance. To constrain long wavelengths in the data, an independent data set, the Australia-wide Airborne Geophysical Survey (AWAGS) airborne magnetic data, was used to control the base levels of the survey data. This survey data is essentially levelled to AWAGS.

Bloods Range 1:250 000, R502 historical topographic map

The R502 series of maps has been replaced by the National Topographic Map Series (NTMS). The R502 series consists of 542 map sheets and covers Australia at a scale of 1:250,000. It was compiled from aerial photography, but only about one quarter of the series was contoured. The standard sheet size is 1 degree of latitude by 1.5 degrees of longitude. Transverse Mercator map projection and Clark 1858 datum were used. Coverage of the country was completed in 1968.

Hill River 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.

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.
