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The R502 series of maps has been replaced by the National Topographic Map Series (NTMS).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

Gravity Survey 2005, NT, CR20050298-EL9695, CR20050315-EL22909 (P200480), 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 Gravity Survey 2005, NT, CR20050298-EL9695, CR20050315-EL22909 (P200480) contains a total of 57 point data values acquired at a spacing between 500 and 1000 metres. The data is located in NT and were acquired in 2002, under project No. 200480 for BHP Group Ltd; Mithril Resources Ltd.

Hydrogeology Map of Australia (G.Jacobson and JE.Lau Hydrogeology Map)

The principal aquifers of Australia (National Geoscience Dataset) has been used to produce the hydrogeology map of the Australian continent.  It is described in terms of principal aquifers, defined as those producing the best quality water at highest yield from shallowest depth. Aquifers are defined as porous or fissured, and subdivided in terms of their extent and productivity; these aspects are shown in solid colour on the map.

Electric logging of Port Fairy borehole, Parish of Belfast No 4, Victor April, 1959

Single point resistivity, self potential and gamma ray legs were run in the new Port Fairy water bore currently being drilled by the Victorian Mines Department. The object of the logging was to assist in determining the best place to set casing in order to seal off aquifers likely to contain saline water. The logs are interpreted as clearly indicating a depth range in which the casing should be set.

BMR submission to 1988 review of BMR

In order to assist the comprehensive review of BMR's role and functions (first
term of reference), this document describes the strategic aims which have been
developed for all components of the program, and illustrates in some detail
the manner in which the resource assessment function has been developed. The
database function is closely intermeshed with the two other functions: its
importance is demonstrated by the establishment by Government this year of the
National Resource Information Centre (NRIC) , involving both BMR and BRR.

A new perspective on regional structural architecture across the offshore Otway Basin.

Geoscience Australia has undertaken a regional seismic mapping study of the offshore Otway Basin extending across the explored inner basin to the frontier deep-water region. Seismic interpretation covers over 18000 line-km of new and reprocessed data acquired in the 2020 Otway Basin seismic program and over 40000 line-km of legacy 2D seismic data. We present new basin-scale isochore maps that show the distribution of the Cretaceous depocentres. Maps for the Lower Cretaceous Crayfish and Eumeralla supersequences, together with those recently published for the Upper Cretaceous Shipwreck and Sherbrook Supersequences, completes the set of isochore maps for the main tectonostratigraphic basin intervals. Mapping of basement involved faults has revealed structural fabrics that have influenced depocentre development. The tectonostratigraphic development of depocentres and maps of deep crustal units delineate crustal thinning trends related to late Cretaceous extension phases. This work highlights the need to review and update structural elements. For example, the boundary between the Otway and Sorell basins is now geologically constrained. The refinements to the tectonostratigraphic evolution of the Otway Basin presented here have important implications for the distribution and potential maturity of petroleum systems, especially with regard to heat flow associated with crustal extension.
