Phanerozoic OZ SEEBASE v2 GIS

Abstract

This dataset and its metadata statement were supplied to the Bioregional Assessment Programme by a third party and are presented here as originally supplied.

The OZ (Australian) SEEBASE™ compilation represents many years of work by FROGTECH in the Australian petroleum, mineral and coal sectors.

During this time FROGTECH has undertaken numerous projects in Australia with both the private and government sectors.

These projects have resulted in the development of a model of the geological evolution of the Phanerozoic Basins that is summarised in a GIS and a report. The model is consistent with a wide range of data-sets including airborne and satellite remote sensing, seismic, well and outcrop observations.

The Phanerozoic basins of Australia is formed by the repeated reactivation of long-lived basement structures. By understanding the genesis and geometry of the old basement structures, we have produced a consistent, testable model for the evolution of the basins that explains their structural framework and architecture. The SEEBASE™ model and structural interpretation can now be used as the basis for a new understanding of the sequence stratigraphy and petroleum systems of the Late Proterozoic to Recent basins of Australia.

OZ SEEBASE™ Version 2 includes updated OZ SEEBASE™ and SEEBASE™ Derivative files (sediment thickness and basement thickness - originally called "Crustal thickness" in Version 1). Geophysical and DEM images have been changed from ecws to jpgs to avoid ArcGIS ecw compatibility issues. Updated regions include: Darling Basin (NSW), Sydney Basin (NSW), Renmark Trough (SA), Stuart Shelf (SA), and the Neoproterozoic Redcliff Pound Group (WA/NT).

Dataset History

OZ SEEBASE was supplied to Geoscience Australia by Frog Tech, the creators and collaborators of this data. Full metadata for each data element (feature class, raster, etc) can be viewed in the description tab of ArcCatalog.

This data was supplied with the following caveat: "OZSEEBASE was a project funded by Shell and supported by GA but, at the time, the exact licensing wasn't clear and hasn't been addressed since. However, it is freely available and there are no restrictions on useage. We just ask for Attribution where it is used"
