Sequence framework and key petroleum play elements of the Neoproterozoic-Cambrian succession of the Amadeus Basin

Sequence framework and key petroleum play elements of the Neoproterozoic-Cambrian succession of the Amadeus Basin

Publication Name: CENTRAL AUSTRALIAN BASINS WORKSHOP 1993 (CABS 1)
Authors: J. M. Kennard, J. F. Lindsay
Date Published: September 1993

 

Abstract:

Sequence stratigraphic concepts are used to identify and analyse depositional sequences in theNeoproterozoic -Cambrian succession (Pertaoorrta Group) of the intracratonic Amadeus Basin. This analysis is based largely on the recognition of facies disc...

Structural and tectonic framework of the Amadeus Basin, with some deep seismic examples

Structural and tectonic framework of the Amadeus Basin, with some deep seismic examples

Publication Name: CENTRAL AUSTRALIAN BASINS WORKSHOP 1993 (CABS 1)
Authors: R.J. Korsch, R.D. Shaw, B.R. Goleby
Date Published: September 1993

 

Abstract:

In the Late Proterozoic, the Amadeus Basin developed during an initial period of subsidence due to an extensional and/or thermal event which was followed by subsidence driven by thermal relaxation of the lithosphere (Stage 1). A second, less intense,...

Geochemical tools for finding the oil window in Proterozoic and early Palaeozoic petroleum source rocks

Geochemical tools for finding the oil window in Proterozoic and early Palaeozoic petroleum source rocks

Publication Name: CENTRAL AUSTRALIAN BASINS WORKSHOP 1993 (CABS 1)
Authors: Roger E. Summons, Dennis Taylor, Christopher J. Boreham
Date Published: September 1993

 

Abstract:

There is a perception that maturity estimates based on geochemical investigations need to be assessed against the "yardstick' of the more conventional vitrinite reflectance. However, in Proterozoic and Early Palaeozoic sediments, which pre-date the e...

Cambrian biostratigraphic events within central and northern Australian basins

Cambrian biostratigraphic events within central and northern Australian basins

Publication Name: CENTRAL AUSTRALIAN BASINS WORKSHOP 1993 (CABS 1)
Authors: J. H. Shergold
Date Published: September 1993

 

Abstract:

There is a demonstrated relationship between biostratigraphic and sequence stratigraphic units. Undoubtedly, sequence stratigraphic analysis is enhanced by the presence of a detailed biostratigraphy developed either within a basin or correlated to it...

Review of Neoproterozoic and Early Palaeozoic acritarch biostratigraphy

Review of Neoproterozoic and Early Palaeozoic acritarch biostratigraphy

Publication Name: CENTRAL AUSTRALIAN BASINS WORKSHOP 1993 (CABS 1)
Authors: W. Zang
Date Published: September 1993

 

Abstract:

Acritarchs (phytoplankton) and cyanobacteria probably dominated the biosphere before explosion of the Ediaeara Fauna in the Neoproterozoic. Their distribution was generally related to sedimentary environments and shows secular variation through geolo...

The Larapintine petroleum system

The Larapintine petroleum system

Publication Name: CENTRAL AUSTRALIAN BASINS WORKSHOP 1993 (CABS 1)
Authors: M. Bradshaw
Date Published: September 1993

 

Abstract:

Phanerozoic Australian sedimentary sequences can be grouped into six broad petroleum systems: termed the Larapintine, Gondwanan, Westralian, Austral, Capricorn and Murta systems. Establishing a petroleum system framework stresses the linkages between...

The Neoproterozoic Centralian Superbasin

The Neoproterozoic Centralian Superbasin

Publication Name: CENTRAL AUSTRALIAN BASINS WORKSHOP 1993 (CABS 1)
Authors: M. R. Walter, J. J. Veevers, C. R. Calver, K. Grey
Date Published: September 1993

 

Abstract:

In Neoproterozoic times 2 million km2 of Australia were occupied by a single depositional system, the Centralian Superbasin. The Superbasin was disrupted 590-530 Ma ago by a central uplift, and then dismembered by late Palaeozoic tectonism to form nu...

Regional controls on Australia’s intracmtonic basins

Regional controls on Australia’s intracmtonic basins

Publication Name: CENTRAL AUSTRALIAN BASINS WORKSHOP 1993 (CABS 1)
Authors: J.F. Lindsay, R.J. Korsch
Date Published: September 1993

 

Abstract:

In the Late Proterozoic, several broad shallow intracratonic depressions appeared across a large area of central Australia (Fig. 1). The basins, which all contain Neoproterozoic to early Palaeozoic shallow marine to fluvial successions, appear to hav...

Basement tectonic framework to central Australian basins, based on 1:5 000 000 potential field data

Basement tectonic framework to central Australian basins, based on 1:5 000 000 potential field data

Publication Name: CENTRAL AUSTRALIAN BASINS WORKSHOP 1993 (CABS 1)
Authors: R.D. Shaw, C.V. Reeves, M.P. Morse, C. Tarlowski
Date Published: September 1993

 

Abstract:

This paper brings up to date our understanding of basement geology in the region of the central Australian basins as a result of an ongoing AGSO project to produce a Basement Tectonic Map of Australia at 1:5 000 000 scale based on regional magnetic a...

South Australian record of a Rodinian epicontinental basin and its mid-Neoproterozoic breakup to form the PalaeoPacific Ocean

Publication Name: CENTRAL AUSTRALIAN BASINS WORKSHOP 1993 (CABS 1)
Authors: C. McA. Powelll, C.G. Gatehouse, B. Krapez, Z.X. Li, W.V. Preiss
Date Published: September 1993

 

Abstract:

Synthesis of available palaeomagnetic data shows that between 1050 Ma and 725 Ma the palaeomagnetie poles for Laurentia and East Gondwanaland overlap when the continents are reconstructed as the Rodinia supereontinent (Fig. 1). By 580 Ma Laurentia an...
