Frome 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The R502 series of maps has been replaced by the National Topographic Map Series (NTMS).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.

Hann River, Qld, 1991 (P570), 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 Hann River, Qld, 1991 survey were acquired in 1991 by the QLD Government, and consisted of 55546 line-kilometres of data at 400m line spacing and 100m 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.

Jamestown dose 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. The terrestrial dose rate grid is derived as a linear combination of the filtered K, U and Th grids. A low pass filter is applied to this grid to generate the filtered terrestrial dose rate grid.
This Jamestown dose grid geodetic has a cell size of 0.00021 degrees (approximately 21m) and shows the terrestrial dose rate of the SMMSP - MagSpec - Jamestown, SA, 2002 (2002/01). The data used to produce this grid was acquired in 2002 by the SA Government, and consisted of 8919 line-kilometres of data at 100m line spacing and 60m terrain clearance.

Notes on the stratigraphy and palaeontology of Tasmanian Cambrian, Ordovician and Silurian rocks

At the invitation of Prof. S.W. Carey, the author visited Tasmania during the period 15th November to 2nd December, 1950, to take part in discussions on Cambrian geology in Tasmania and to learn in the field the results of recent investigations on Tasmanian older Palaeozoic rocks. During the visit the author had the opportunity of expressing his opinions both on newly discovered fossils and on the age of some Palaeozoic units, and the main object of this report is to record these opinions.

Paterson North TEMPEST AEM Survey, WA, 2008 Final Data (P1168)

During 2007 and 2008 and under the Australian Government's Onshore Energy Security Initiative, Geoscience Australia acquired airborne electromagnetic (AEM) data over the Paterson Province of Western Australia. The main purpose of the survey was to provide additional geophysical/geological context for unconformity and palaeochannel style uranium mineral systems and thereby promote related exploration. The survey data will also provide information on depth to basement, which is of general interest to explorers, and will be used as an input into a ground water evaluation of the region.

Correlation of Olary and Broken Hill domains, Curnamona Province: possible relationship to Mount Isa and other North Australian Pb-Zn-Ag-bearing successions

The 300-Mt Broken Hill Pb-Zn-Ag orebody is in the Broken Hill Domain, which, together with the contiguous Olary Domain, constitutes the southern part of the Curnamona province of eastern Australia. The Curnamona province is dominated by medium- to high-grade metamorphic rocks of the Paleoproterozoic Willyama Supergroup and is the focus of exploration for base metals, gold, and uranium. A robust chronology of the ~1720 to 1640 Ma Willyama Supergroup provides the basis for temporal correlations on a regional scale between the Olary and Broken Hill Domains, and possibly on an interbasin scale between the southern Curnamona province and the Carpentaria zinc belt in northern Australia (Mount Isa, McArthur River). 
SHRIMP U-Pb zircon analyses from tuffaceous metasedimentary rocks provide ages for two new chronostratigraphic marker horizons in the Olary Domain. Firstly, the 1693 Â± 3 Ma Plumbago Formation, and an equivalent metasiltstone in the Broken Hill Domain, confirm earlier suggestions that the base metal-enriched Bimba Formation is stratigraphically equivalent to the Ettlewood Calc-Silicate Member in the lower part of the ~1685 to 1695 Ma Broken Hill Group. Secondly, tuffaceous sedimentary rocks in the Mount Howden Subgroup of the Olary Domain have a maximum age of 1651 Â± 7 Ma, thus suggesting correlation with a similar lithostratigraphic succession in the middle Paragon Group at Broken Hill. 
The lithostratigraphy, depositional ages, and inferred intervals of missing rock in the Curnamona province are broadly similar to the basin evolution of the Carpentaria zinc belt of northern Australia, suggesting possible chronostratigraphic correlations between Broken Hill and the Mount Isa-McArthur regions. The Broken Hill Group (~1695-1685 Ma) is considered to be time-equivalent to the Prize Supersequence in northern Australia, with possible implications for their respective depositional and metallogenic histories. Depositional ages from the middle Paragon Group (1655 Â± 4 Ma, 1657 Â± 4 Ma) at Broken Hill are closely comparable to the ca. 1655 Ma ages of tuff units associated with the Mount Isa and Hilton Pb-Zn-Ag orebodies (Gun Supersequence of northern Australia). The upper Paragon Group is considered to be the same age (ca. 1640 Ma) as that part of the Isa superbasin that hosts the McArthur River (HYC) deposit of the McArthur basin, the Walford deposit, and other Pb-Zn-Ag-mineralized sequences of the Lawn Hill platform.

Don King Notebook 3 : Diary 1951

Three geologists left Australia in 1951 to conduct geological surveys in Pakistan, under the auspices of the Colombo Plan which provides technical assistance for member countries in South and South East Asia. The main objects were to conduct an economic and general geological survey of a selected part of the Gilgit Agency, to examine the alluvial-gold prospects of the Chitral River, and, if time permitted, to discuss the Sind and East Bengal lignites with the Director of the Pakistan Geological Survey.
The field notebooks contain the geological observations recorded by the geologists during their trip. Files include a scanned copy of the original handwritten field notebook, transcription of the notebook’s contents, and a csv file of the transcription with Text Encoding Initiative (TEI) tags. The original field notebooks are held at the N.H. (Doc) Fisher Geoscience Library at Geoscience Australia, Canberra.

This magnetic grid has a cell size of 0.00077 degrees (approximately 80m).The data are in nanoTesla (or nT). The data used to produce this grid was acquired in 2000 by the NSW Government, and consisted of 54898 line-kilometres of data at line spacing between 200m and 400m, and 60m terrain clearance. The data has had a variable reduction to the pole applied to centre the magnetic anomaly over the magnetised body. The VRTP processing followed a differential reduction to pole calculation up to 5th order polynomial. Magnetic inclination and declination were derived from the IGRF-11 geomagnetic reference model using a data representative date and elevation representative of the survey.

Pacific Sea Level and Geodetic Monitoring Project Levelling & GNSS Monitoring Survey Reports: Lautoka, Fiji, January 2019

The Australian Bureau of Meteorology (BoM), Geoscience Australia (GA) and the Pacific Community (SPC) work together on the Australian Aid funded Pacific Sea Level and Geodetic Monitoring Project (PSLGMP). The project is focused on determining the long-term variation in sea level through observation and analysis of changes in the height of the land (using Global Navigation Satellite System (GNSS) data) and changes in the sea level (using tide gauges managed and operated by the BoM. It is the role of GA and SPC to provide information about ‘absolute’ movement of the tide gauge (managed by BoM) using GNSS to continuously monitor land motion and using levelling (SPC) to measure the height difference between the tide gauge and GNSS pillar every 18 months.
Land movement caused by earthquakes, subsidence and surface uplift have an important effect on sea level observations at tide gauges. For example, a tide gauge connected to a pier which is subsiding at a rate of 5 mm per year would be observed as a rate of 5 mm per year of sea level rise at the tide gauge. Because of this, it is important to measure, and account for, the movement of land when measuring ‘absolute’ sea level variation - the change in the sea level relative to the centre of the Earth. Relative sea level variation on the other hand is measured relative to local buildings and landmass around the coastline.
Geoscience Australia’s work enables more accurate 'absolute' sea level estimates by providing observations of land motion which can be accounted for by BoM when analysing the tide gauge data.
This report provides the results of the GNSS monitoring survey &amp; high precision level survey completed between the Sea Level Fine Resolution Acoustic Measuring Equipment (SEAFRAME) Tide gauge and the GNSS Continuously Operation Reference Station (CORS) in Lautoka, Fiji from 9th to 16th January 2019. It also provides an updated ellipsoidal height of the tide gauge derived from GNSS time series analysis and precise levelling observations.
