Cobar P5009 EXT 4 total magnetic intensity grid

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.
This Cobar P5009 EXT 4 total magnetic intensity grid has a cell size of 0.00039074 degrees (approximately 40m). The units are in nanoTesla (or nT). The data used to produce this grid was acquired in 2021 by the NSW Government, and consisted of 53617 line-kilometres of data at 200m line spacing and 60m terrain clearance.

AUSGeoid98 v.1.0 data files:  (sc51-04)

AUSGeoid98 data files contain a 2 minute grid of AUSGeoid98 data covering the Australian region, which you can use to interpolate geoid-ellipsoid separations for the positions required.You can use your own interpolation software, or you can use Geoscience Australia's Windows Interpolation software (Winter). The data files are text files in a standard format that cover the same area as standard topographic map areas. Files covering both 1:250,000 (approximately 100 x 150 km) and 1:1,000,000 (approximately 400 x 600 km) map areas are available. There is a 4 minute overlap on all sides of each area. Data format: AUSGeoid98 data files have a header record at the start of each file, to distinguish them from the superseded AUSGeoid93 data files. AUSGeoid98 data files show the geoid-ellipsoid separation to 3 decimal places, while the superseded AUSGeoid93 data files showed only 2 decimal places. AUSGeoid98 deflections of the vertical were computed from the geoid-ellipsoid separation surface, while the AUSGeoid93 deflections of the vertical were computed from OSU91A.

A new nannofossil zone based on the Santonian Gingin Chalk, Perth Basin, Western Australia

Studies of the Gingin Chalk have indicated that it is Santonian in age; these studies did not deal with calcareous nannofossils. Santonian biostratigraphy in terms of nannofossils is problematic. The relative ranges of several Upper Cretaceous key nannofossil species, particularly those of the Santonian, are controversial. Precise determination of these ranges hinges on suitable illustration of the species using optical microscopy for successful subsequent identifications. Light microscopic illustrations of most of the nannofossil species recovered from the Gingin Chalk are presented. Based on several species among the Gingin Chalk assemblages a new Santonian zone, the Lucianophabdus maleformis Zone, is proposed. Thus, on the basis of sequential earliest occurrences of several key species, the late Coniacian-early Campanian interval can be subdivided into: the Marthasterites furcatus, Lucianorhabdus maleformis, and Broinsonia parca Zones.

Australian Petroleum Systems. Dampier Sub-basin module

This module is part of the AGSO-APIRA Australian Petroleum Systems Project. 
Eight basin modules were examined which covered almost the entire North West Shelf, the Petrel Sub-basin, as well as the Papuan basin in PNG. 
Two relational databases were established containing the biostratigraphic data (STRATDAT) and reservoir, facies and hydrocarbon shows data (RESFACS). These databases were linked by application programs which allow time series searching using geologically intelligent routines. 
Petroleum systems analyses were conducted on each area, with key results focussing upon the comparison of source quality and timing of generation between similar systems in different areas.

Sedimentological studies on the Stairway Sandstone of central Australia

The Stairway Sandstone was studied in the field in 1962 and 1963 during the reconnaissance geological mapping of the Amadeus Basin. In 1964 rather more detailed work was carried out: sections were measured and cross-bedding determined throughout the Amadeus Basin, and the phosphorites were examined in some detail because of their possible economic significance. In 1965 and 1966 surface and subsurface material was studied in detail to determine the provenance, environment of deposition, and palaeography of the formation. This work was done partly in the laboratories of the Bureau of Mineral Resources, and partly in the Department of Geology of the Australian National University, Canberra (under the sponsorship of the Bureau of Mineral Resources).
