This disc contains scanned PDF copies of uranium-related reports held by Geoscience Australia from the archives of the former Australian Atomic Energy Commission. These reports date from the 1950s to the 1980s. The reports are a mix of exploration reports, geological and geographical maps, proposals, feasibility studies, estimations, reserve information, drill hole data and drill cross section files.

ERMapper data file, contains a worldwide Digital Elevation Model with a horizontal grid spacing of 30 arc seconds, approximately 1 kilometre.

This is an excel spreadsheet for calculating easting and northing coordinates from a input latitude and longitude, using Redfearn's formula. The calculation may also be done in reverse.

This disc contains scanned PDF copies of geophysical and geological logs held by Geoscience Australia from the archives of the former Australian Atomic Energy Commission. These logs date from the around 1973 to 1975, and are specific to Honeymoon and Gould's Dam deposits. Two other discs with PDF scans of exploration in South Australia also exist and may be of interest.

The formation of passive margins has been intensively studied on the Iberian-Newfoundland margins for over two decades leading to complex models for the formation of conjugate nonvolcanic rifted margins. The main area of debate is focussed on deciphering the nature of the so-called transitional zone between unambiguous continental and oceanic crust. The transitional zone often displays characteristics of both continental and oceanic crust. The Great Australian Bight and Wilkes Land margins are type-examples of conjugate nonrifted volcanic margins, but much less well studied than the Iberian-Newfoundland margins. Research along the Southeast Indian Ocean margins has been propelled by Australia's submission to the United Nations Convention of the Law of the Sea, yet the study of the margins has been limited to research on particular regions on either the Australian or Antarctic margins. No consistent stratigraphy has been derived that would allow a unified study of this margin pair. This thesis uses seismic and potential field data to provide a consistent interpretation across the two margins in terms of sedimentary sequences and crustal structure for the first time. The interpretation of both margins provides insight into the nature and formation of the transitional zone. A new sequence stratigraphy for the Wilkes Land margin has been developed to correlate with the interpretation of Totterdell et al. (2000) along the Great Australian Bight margin. Combined with the crustal structure classification of Leitchenkov et al. (2007) a revised model for the breakup and formation of the transitional zone was developed. The formation of the transitional zone is interpreted to be the result of extension of the two plates and the successive breakup of continental crust and mantle followed by the emplacement of oceanic mantle, initially without the formation of oceanic crust. The presence of the Moho within the seismic data shows that the transitional zone is underlain by mantle rocks. Continental mantle is interpreted to be exhumed to form prominent basement highs on both margins. Seaward of these highs, the change in basement architecture and the presence of magnetic anomaly 34 (83Ma) is interpreted to correlate with the juxtaposition of continental mantle and the emplacement of oceanic mantle. This is consistent with well subsidence data from Totterdell et al. (2000) which shows a change in the rate of subsidence at this time. The location of the Transitional Zone-Ocean Boundary (TZOB) and Transitional Zone- Continent Boundary (TZCB) are repositioned as a result of this study. The TZOB is located further landward of previous interpretations by Sayers et al. (2001) and Colwell et al. (2005). The interpretation of the transitional zone being underlain by mantle rocks renders the term Continent-Ocean Boundary (COB) invalid as, continental crust is not found immediately next to oceanic crust.
