AUSGeoid98 v.1.0 data files:  (sl55-07)

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 Data format: AUSGeoid98 data files have a header record at the start of each file, to distinguish them from the superseded AUSGeoid93 data files. AUSGeoid98 data files show the geoid-ellipsoid separation to 3 decimal places, while the superseded AUSGeoid93 data files showed only 2 decimal places.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.

SthGascoyne GroundElevation geodetic

Digital Elevation data record the terrain height variations from the processed point- or line-located data recorded during a geophysical survey. This SthGascoyne GroundElevation geodetic is elevation data for the South Gascoyne Gravity Survey (P201061). This survey was acquired under the project No. 201061 for the geological survey of WA. The grid has a cell size of 0.005 degrees (approximately 530m).  This grid contains the ground elevation relative to the geoid for the South Gascoyne Gravity Survey (P201061). It represents the vertical distance from a location on the Earth's surface to the geoid. The data are given in units of meters. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.

Indexes to the analyses of calcium and magnesium carbonate rocks and other sedimentary rocks rich in either calcium, magnesium, or phosphorous

Originally it was intended that the calcium and magnesium carbonate rocks and others rich in one or other of these elements should be published as a Bulletin, being Part III of a series of which Part I (Bulletin 65, already published) contained analyses of igneous and metamorphic rocks and Part II (Bulletin 78, already published) contained analyses of non-carbonate and non-phosphate sedimentary rocks. However, owing to the rising cost of publication and to the fact that the analyses of most carbonate rocks are only partial analyses, Part III has not been published although the compilation was completed in 1967. As in the case of Parts I and II the literature was searched for analyses made before 1960 as the introduction of rapid methods of analysis has made available a great flood of chemical data familiar to present research workers, and it was thought that easy access to older analyses may prove useful to them.

Great Artesian Basin - Hutton Aquifer - Alkalinity

Data used to produce the predicted Alkalinity map for the Hutton Aquifer and equivalents in the Hydrogeological Atlas of the Great Artesian Basin (Ransley et.al., 2015).
There are four layers in the Hutton Aquifer and equivalents 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 Hutton Aquifer and equivalents Alkalinity map is one of four hydrochemistry maps for the Hutton Aquifer and equivalents and 24 hydrochemistry maps in the Hydrogeological Atlas of the Great Artesian Basin (Ransley et.al., 2015). 
This dataset and associated metadata can be obtained from www.ga.gov.au, using catalogue number 81708.

Broken Hill Exploration Initiative - Ameroo Hill GeoPDF

As part of the Broken Hill Exploration Initiative (BHEI), Geoscience Australia and the Department of Primary Industries South Australia (PIRSA) recently embarked on a two-year joint project to better understand the deformational history and tectonic evolution of Palaeoproterozoic rocks in the Outalpa Inlier, South Australia. This project is one of several structural studies undertaken on these rocks although to date no consensus has emerged regarding the number, orientation and geometry of the main deformational events. To address this problem, detailed structural and stratigraphic studies were undertaken around Ameroo Hill and Tommie Wattie Bore region in the central part of the inlier where a well defined stratigraphic succession is exposed.
Comparable studies undertaken in other parts of the Olary Domain indicate that the same stratigraphy and structural history are developed across the entire Curnamona Province and that the structures developed around Ameroo Hill are not atypical of the province as a whole. Included in the Olary stratigraphy is the regionally extensive and highly prospective "Bimba Formation", a marble and calc-silicate dominated unit known for its high base-metal content (Pb, Zn, Mn, Cu, Co). Geochronological studies have recently confirmed this unit as a correlative of the Ettlewood Calc-silicate in the Broken Hill Group and there is growing geochronological evidence (Page et al., 2000) that other parts of the Olary sequence can be similarly matched to equivalent units in the Broken Hill Domain.
Lithostratigraphic nomenclature follows Conor (2000, 2001) who subdivided the Willyama Supergroup into two major units of contrasting magnetic susceptibility and composition: the Curnamona and Strathearn Groups.

RETIRED Surface Reflectance Euclidean, Spectral and Bray-Curtis Median Absolute Deviation 2.1.0

This record was retired 29/03/2022 with approval from S.Oliver as it has been superseded by eCat 146261 DEA Geometric Median and Median Absolute Deviation (Landsat)
This product provides ‘second order’ statistical techniques that follow from the geometric median, which is useful for environmental characterisation and change detection.
The Median Absolute Deviation (MAD) is a generalisation of the classic one-dimensional statistic for multidimensional applications, and is a measure of variance in a dataset through comparison to the median. It is similar in concept to the way that the standard deviation in statistics can be used to understand variance compared to the mean.
