Great Artesian Basin - Cadna-owie Hooray Aquifer - Sodium Concentration

Data used to produce the predicted Sodium map for the Cadna-owie - Hooray Aquifer in the Hydrogeological Atlas of the Great Artesian Basin (Ransle et. al., 2015).
There are four layers in the Cadna-owie - Hooray Aquifer  Sodium 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 Sodium as Na in 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 Sodium 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).

MRTAS SW Tasmania ppm uranium grid geodetic

The radiometric, or gamma-ray spectrometric method, measures the natural variations in the gamma-rays detected near the Earth's surface as the result of the natural radioactive decay of potassium (K), uranium (U) and thorium (Th). The data collected 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 radiometric uranium grid has a cell size of 0.00042 degrees (approximately 40m) and shows uranium element concentration of the South West Tasmania, Tas, 2001 (WTRMP Area D) in units of parts per million (or ppm). The data used to produce this grid was acquired in 2000 by the TAS Government, and consisted of 13701 line-kilometres of data at 200m line spacing and 80m terrain clearance.

The geology and mineral resources of the Chillagoe district, Queensland

This Bulletin presents the results of five months fieldwork carried out by a joint geological party from the Bureau of Mineral Resources and the Geological Survey of Queensland in 1958, and incorporates subsequent scattered field observations in more recent years. The area investigated is covered by the three One-Mile Sheets of Chillagoe, Mungana, and Almaden, and forms the north-western part of the Atherton 1:250,000 Sheet area, North Queensland. Metamorphosed and migmatized Precambrian schist, gneiss, and muscovite granite in the west are separated from folded Palaeozoic geosynclinal sediments by a large fault. The geosynclinal deposits are represented by Upper Silurian to Lower Devonian formations with mixed shelf facies, and, farther east, by the eugeosynclinal flysch sediments of the Middle to Upper Devonian Hodgkinson Formation. Remnants of unconformable lacustrine or estuarine sediments, probably Carboniferous, are also exposed. Upper Permian granites intruded these formations after they had been folded during a Carboniferous orogeny and subsequently eroded, and acid to intermediate volcanics, comagmatic and coeval with the granites, were extruded on a surface of low relief, commonly in ring complexes and cauldron subsidence areas. Associated with the granites is a widespread and varied mineralization which has given rise to numerous deposits of copper, lead, zinc, silver, gold, tungsten, molybdenum, bismuth, tin, fluorspar, and iron. The region remained stable and near sea-level until the Lower Cretaceous transgression from the west, during which sandstone and conglomerate were deposited under littoral conditions. Post-Cretaceous epeirogenesis combined with subsequent stages of faulting and erosion to sculpture the present-day landscape. The area has had an intermittent mining history which reached its zenith in the first ten years of the century, with a partial resurgence in the twenties, and a few subsequent short-lived spasms of activity.

A risk assessment of sulfonylurea herbicides leaching to groundwater

Improvements in agricultural production help sustain the worlds burgeoning population. The question is whether agricultural technologies degrade primary soil and water resources.  Sulfonylurea herbicides provide a good example of the impact of a technical innovation. Higher more-dependable wheat yields were achieved over the entire Australian wheat belt after the introduction of the sulfonylurea herbicides. More recently, farmers have expressed concern about limited recropping options and the accumulation of sulfonylurea residues in some soil types.  A risk/benefit balance sheet for residual sulfonylureas indicates that benefits of sulfonylurea use far outweigh risks, particularly compared with an alternative mechanical weed control option. The overall profile of sulfonylurea herbicides fits well with the characteristics needed for sustainable farming systems. However, two potential problems were identified for sulfonylurea use on alkaline sodic soils: injury of highly susceptible legumes from sulfonylurea carryover and sulfonylurea leaching into groundwater. The risk depends largely on the amount and distribution of rainfall. Thus, problems can be averted if geographical information systems/herbicide simulation models and seasonal weather forecasts are combined to provide site specific recommendations.

Present-day stresses of the Canning Basin, WA

A key focus of the Exploring for the Future program was the Kidson Sub-basin, a large, underexplored and poorly understood depocentre in the southern part of the Canning Basin of Western Australia. The Canning Basin hosts proven petroleum systems and has recently become an area of interest for unconventional hydrocarbon exploration. Several formations within deeper basin depocentres are under investigation. Unconventional petroleum resource evaluation is generally dependent on an understanding of both local and regional stresses, as these exert a control over subsurface fluid flow pathways, as well as the geomechanical properties of reservoir units. Gaps exist in our understanding of these factors within the Canning Basin, and particularly the Kidson Sub-basin where wellbore coverage is sparse. This study identifies a generally NE–SW-oriented regional maximum horizontal stress azimuth from interpretation of borehole failure in five petroleum wells, and a broadly strike–slip faulting stress regime from wireline data and wellbore testing. Variations in stress regime at different crustal levels within the basin are highlighted by one-dimensional mechanical earth models that show changes in the stress regime with depth as well as by lithology, with a general shift towards a normal faulting stress regime at depths greater than ~2.5 km.
