Ana Branch Hydrogeological map of the Murray Basin series 1:250 000

This product has been archived and while it is still available for download, Geoscience Australia can no longer offer related support or advice.
The objectives of hydrogeologically mapping the Murray basin were to generate a set of maps at 1:250 000 scale to: 

show the influence of groundwater on land salinisation and surface water salinity 
delineate useable groundwater resources 
highlight present and potential salinity hazard and 
enhance community awareness and understanding of groundwater systems and processes 

and provide a groundwater data-base for the Murray Basin to facilitate land and water resource management decisions. 
The production of the Murray Basin Hydrogeological Map Series was a major coordinated Government action in the management of groundwater to combat degradation through salinisation and enable sustainable land and water use in the Murray Basin.  The Hydrogeological Map Series was a collaborative effort between the various water authorities of South Australia, Victoria and New South Wales. 
Explaining this product in detail is an article by Evans, W.R. 1992, The Murray Basin Hydrogeological Map Series, Water pp. 20-23.

Dandaloo Gravity (P196436), gravity point data

Gravity data measures small changes in gravity due to changes in the density of rocks beneath the Earth's surface. 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 Dandaloo Gravity (P196436) contains a total of 117 point data values acquired at a spacing of 1609 metres. The data is located in NSW and were acquired in 1964, under project No. 196436 for Wood, A.J..

SAEI (MESA) - Broken Hill Exploration Init., Area BHEI-4, Lake Charles, 1995 (P751), 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 SAEI (MESA) - Broken Hill Exploration Init., Area BHEI-4, Lake Charles, 1995 survey were acquired in 1995 by the SA Government, and consisted of 10866 line-kilometres of data at 200m line spacing and 60m 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.

The Veevers Crater: a possible meteoritic feature

A new crater was discovered in July, 1975 during reconnaissance geological mapping by a joint Bureau of Mineral Resources and Geological Survey of Western Australia field party in the southern part of the Canning Basin, Western Australia. The origin of the crater remains speculative. The possible alternatives are: a diapiric structure, a structure produced from a man-made explosion, a cryptovolcanic structure or a meteorite crater.

The dromornithidae, an extinct family of large ground birds endemic to Australia

Many of Australia's birds are unique to this continent, but none are more impressive than a group of giant ground birds, the Dromornithidae, one member of which may have
exceeded in volume and weight any bird that has ever trod the surface of the earth. Although first discovered in the early 19th century, only two genera (Genyornis and Dromornis), both monotypic, had been recognized when work beginning in the 1950's in central Australia brought to light at least six new forms including three new genera (Barawertornis,
Bullockornis, and Ilbandornis), described for the first time in this paper. Based almost entirely on post-cranial material, the Dromornithidae appear to be most closely related
to the Casuariidae, the only other Australian ratite group, but before a satisfactory higher taxonomic allocation can be made, good cranial material is needed. Unfortunately, the maximum age of known dromornithid fossils is about 15-20 million years, and from that first record to the last in the late Pleistocene, only minor evolutionary changes are known to have occurred, namely: reduction of the forelimb, reduction of the medial digit of the foot, and development of hoof-like ungual phalanges on the foot. A much more fascinating evolutionary picture of this diverse group awaits future palaeontological discoveries.

Robert combined thorium 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 thorium grid has a cell size of 0.00063 degrees (approximately 66m) and shows thorium element concentration of the Robert merge, 1991-1998 in units of parts per million (or ppm). The data used to produce this grid was acquired in 1991 by the WA Government, and consisted of 82900 line-kilometres of data at 300m line spacing and 60m terrain clearance.

Great Artesian Basin - Coreena Wallumbilla Aquifer - Alkalinity

Data used to produce the predicted Alkalinity map for the Wallumbilla - Rolling Downs Group aquifers in the Hydrogeological Atlas of the Great Artesian Basin (Ransley et.al., 2015).
There are four layers in the Wallumbilla  - Rolling Downs Group aquifers  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 Wallumbilla - Rolling Downs Group aquifers Alkalinity map is one of two hydrochemistry maps for the Wallumbilla - Rolling Downs Group aquifers and 24 hydrochemistry maps in the Hydrogeological Atlas of the Great Artesian Basin (Ransley et. al, 2014).

Evidence of an exhalative origin for deposits of the Cobar district, New South Wales: a discussion

Dr Sangsters contribution on the ore deposits of the Cobar district (Sangster, 1979) is of interest in that it views from a different perspective a group of distinctive and economically important deposits whose origin is enigmatic. Despite the advances in ore genesis theory which have seen many of the former hydrothermal replacement deposits described in terms of volcanic processes operating at or near the ocean-ocean floor interface, workers familiar with Cobar geology have been circumspect in assigning to the Cobar deposits a similar mode of origin. The lead-zinc/copper zonation at the CSA and several of the idle mines which so impressed Dr Sangster had not gone un-noticed by local geologists (e.g. Robertson 1974, p. 180). That they have not taken the next, apparently simple step of considering this zonation in terms of the sedimentary-exhalative orebody model is for the good reason that the comparison does not survive detailed examination. In offering comment on Dr Sangsters paper it is appropriate to note firstly several areas where the bases for his interpretation in the CSA Mine area are wrong in fact.

Sequence Stratigraphic Interpretation of Seismic Data North of 26S, Bowen and Surat Basins, Queensland

PROJECT BACKGROUND
The Sedimentary Basins of Eastern Australia (SBEA) Project is a multidisciplinary study of the Bowen, Surat and Gunnedah Basins. It is part of the National GeoscienceMapping Accord and is a collaborative project between the Australian Geological Survey Organisation (AGSO, formerly the Bureau of Mineral Resources, BMR),Geological Survey of Queensland (Department of Minerals and Energy) and New South Wales Department of Mineral Resources (Geological Survey and Coal &amp; Petroleum Geology branches), with cooperation from CSIRO, universities and industry.
The Bowen, Surat and Gunnedah Basins have considerable resource potential and,although there have been regional studies of the basins in the past, there are still uncertainties as to their precise geometry, mode of formation, the response of thebasin to tectonic events in the adjacent orogens, and the control exerted by these events on the timing and generation of hydrocarbons.
OBJECTIVES
The aim of the project is to undertake an integrated basin analysis with emphasis onthe tectonic, structural, sedimentary and thermal histories of the basins in order to assess their economic potential for hydrocarbons. This Record describes the interim products of the second phase of a regional seismic synthesis, and focuses on theapplication of the principles of sequence stratigraphy in the interpretation and integration of industry and BMR seismic data in the Bowen and Surat Basins,Queensland, between 23Â°30'S and 26Â°S (Fig. 1). It also includes examples of isopach and structure contour maps, in reduced format, based on this phase of interpretation, and briefly outlines the methods and techniques used to produce these maps. Themaps are available through the AGSO Sales Centre, and digital data from the PetroseisTM System Software are available in various file formats.

Discovering a treasure map

Sustainable development and the transition to a clean-energy economy drives ever-increasing demand for base metals, substantially outstripping the discovery rate of new deposits and necessitating dramatic improvements in exploration success. This talk presents the tale of the surprising discovery that 85% of sediment-hosted base metals, including all giant deposits, in Australia and around the world, occur above the transition between thick and thin portions of tectonic plates. It is a story of integrated geoscience, which builds on decades of research in geology, geochemistry and geophysics through a global partnership, which has transformed the search for new exploration frontiers.
