This project was initiated by Geoscience Australia to provide an integrated regional interpretation of basement composition, structure and depth in the Bass Basin, and investigate the effect of basement geology on basin evolution and petroleum systems. SRK Consulting was contracted by Geoscience Australia in June 2001.Structurally Enhanced view of Economic Basement.This metadata encompasses shape files found in the "seebase" directory on the CD-ROM. They are as follows: -

basement_terranes.shp

late_cretaceous_flts.shp

mid_cretaceous_flts.shp

Data quality

Lineage:

SRK Consulting collected numerous source data from alot of different organisations. They used their own processing methods on the various source data to make their interpretations. These methods are described in the report that came with the data. To veiw SRK Consulting's report on these data, please read the "more metadata" component of this document to see how to access it.

Positional accuracy:

The data is a composit product and the positional accuracy is dependand on the source data. The variability of the source data is discussed in SRK Consulting's report. To veiw SRK Consulting's report on these data, please read the "more metadata" component of this document to see how to access it.

Attribute accuracy:

The data was externally produced for Geoscience Australia in a contractual agreement with SRK Consulting to generate these data and therefore it is assumed that all the information is highly accurate and complete. Additionally the majority of the attributes pertain to interpretations, and therefore can only be verified against source information, not actual features. To veiw SRK Consulting's report on these data, please read the "more metadata" component of this document to see how to access it.

Logical Consistency:

All data has been visually verified by SRK Consulting proir to giving it to Geoscience Australia. Also scientifc staff at Geoscience Australia have visually verified the consistency of the data.

Completeness:

As Geoscience Australia had a contractual agreement with SRK Consulting to generate these data and therefore it is assumed that all the information is highly accurate and complete.

SRK Consulting's approach primarily relies on the interpretation of magnetic and gravity data, calibrated with many other datasets including mapped geology, event histories, wells and seismic. SRK utilises a bottom-up approach to basin analysis, starting with a rigorous understanding of basement geology. By integrating the plate-scale kinematic event history for the area of interest, an interpretation of the basins structural evolution through time can be mapped. Combined with a SEEBASE map of depth to basement, this data can be used to understand basin phase architecture and the petroleum systems developed within the basin.

For additional information on the derivation of this data, please consult SRK Consulting's report on this project. The report is in Acorbat "pdf" format and can be accessed via the directory structure (bass_gis/pdf/seebase_report.pdf) or via the "BASS Reports" menu in the ArcView Project.
