Ballarat airborne geophysical survey 1992: operations report

The Australian Geological Survey Organisation (formerly the Bureau of Mineral Resources,
Geology and Geophysics) flew an airborne geophysical survey of 45 500 line km over a large part
of the Ballarat 1:250 000 Map Sheet area during March and April, 1992.
This survey, which formed part of the National Geoscience Mapping Accord, was flown along eastwest
flight lines 400m apart at an altitude of 100m above ground level. An area in the south-west of
the survey area was infilled with additional lines to reduce the line separation to 200m. The NSW
Department of Mineral Resources funded the additional flying.
The total magnetic intensity and gamma-ray spectrometric data which were collected during the
survey, have been processed and are available for purchase, in both digital (position located data
and grids) and map form, from the Australian Geological Survey Organisation.

Total Magnetic Intensity Grid of Australia 2019 - First Vertical Derivative (1VD)

Total magnetic intensity (TMI) data measures variations in the intensity of the Earth 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 first vertical derivative (1VD) grid is derived from the 2019 Total magnetic Intensity (TMI) grid of Australia which has a grid cell size of ~3 seconds of arc (approximately 80 m). As the vertical derivative filter is essentially a high-pass filter, longer wavelengths are suppressed, and shorter wavelengths emphasized. The magnetic units of the data are in nT per metre.

Kidson AreaB 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 0.00083 degrees (approximately 89m) and shows uranium element concentration of the Kidson Areas A &amp; B, WA, 1996 in units of parts per million (or ppm). The data used to produce this grid was acquired in 1996 by the WA Government, and consisted of 128005 line-kilometres of data at 400m line spacing and 60m terrain clearance.

Great Artesian Basin - Cadna-owie Hooray Aquifer - 18O

Data used to produce the predicted Oxygen-18 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 Oxygen-18 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.
Oxygen-18 units are 18O SMOW. 
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 Oxygen-18 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).

Earthquake duration magnitudes in southeast Australia, accounting for site, seismograph and source

A new expression with superior consistency in the calculation of magnitude from earthquake coda duration has been developed.  The need to take into consideration the site, the seismograph characteristics and the source has been investigated. The expression is valid for distances up to 1000 km in southeast Australia except where the source is located on some other major geological foundation, for example the Australian shield or the Tasman Sea.  The expression takes the form:  MD = p1 + p2(log(SDD))P3 + p4Re-p5R   .  MD is duration magnitude, and the parameters in the above expression are determined by regression based on local magnitude ML.  Duration, D, is in seconds, R is the hypocentral distance in kilometres, and pn are parameters.  Parameter p1 zeroes the function to give values similar to ML and accounts for the definition of duration; p2 and p3 give the shape of the variation with duration; and p4 and p5 give the variation with distance.  SD is the  duration site correction factor , which varies from site to site and can be easily determined by comparing particular site durations with average durations.  If the network data are electronically recorded, the value of SD for all sites can be continually monitored and updated. Because of the different methods of estimating D for the analogue and digital seismographs, a value of the parameter p1 for each seismograph type is necessary.  analogue MD = - 0.46 + 0.45(log(SDD))2.4 + 0.0045Re-0.002R  .  digital MD = - 0.20 + 0.45(log(SDD))2.4 + 0.0045Re-0.002R  .  The above expressions present the relationship between MD, D (measured to double the background level) and R in southeast Australia for magnitudes between MD 0 and 5 and for distances from a few km to 1000 km.

Standard curves for interpretation of magnetic anomalies due to thin dykes of finite depth extent

Standard curves for the interpretation of magnetic anomalies due to thin finite dykes were computed for various ratios of dyke length (measured down the dip) to depth of burial. Families of curves for a given field inclination and dip of dyke are produced for various ratios of dyke length to depth of burial. The curves so produced are suitable for interpretation of anomalies in the intensity of the vertical, horizontal, and total field.

Carpentaria Basin hydrogeological inventory

This Carpentaria Basin dataset contains descriptive attribute information for the areas bounded by the relevant spatial groundwater feature in the associated Hydrogeology Index map. Descriptive topics are grouped into the following themes: Location and administration; Demographics; Physical geography; Surface water; Geology; Hydrogeology; Groundwater; Groundwater management and use; Environment; Land use and industry types; and Scientific stimulus.
The Carpentaria Basin is a vast intra-cratonic sedimentary basin situated on and offshore in north-eastern Australia, covering around 550,000 square kilometres across Queensland and the Northern Territory. It comprises predominantly sandstone-rich rock units deposited during sea level highs from the Late Jurassic to Mid Cretaceous. The basin overlies a heterogeneous Proterozoic basement and is separated from contemporaneous sedimentary structures by basement highs and inliers.
Four main depocentres within the larger Carpentaria Basin form four major sub-basins: the Western Gulf Sub-basin, Staaten Sub-basin, Weipa Sub-basin, and Boomara Sub-basin. While the basin is extensive and continuous in Queensland, it becomes more heterogeneous and discontinuous in the Northern Territory. Remnants of the basin's stratigraphy, referred to as the Dunmarra Basin, are found along the Northern Territory coast and inland.
The depositional history commenced during the Jurassic with down warping near Cape York Peninsula, resulting in the Helby beds and Albany Pass beds' concurrent deposition. The basin experienced marine transgressions during the Cretaceous, with the Gilbert River Formation widespread and the Wallumbilla Formation occurring during sea level highs. The Carpentaria Basin's strata are relatively undeformed and unmetamorphosed.
The Northern Territory sequence displays slightly different stratigraphy, limited to the height of the Aptian marine transgression above the Georgina Basin. The Walker River Formation and Yirrkala Formation represent key units in this area, outcropping as tablelands and mesas largely unaffected by tectonism.
