Abstract

These data represent the OZCHRON database of physical age determinations of Australian rocks, and the radiogenic isotope ratios used in determining the ages. OZCHRON datasets comprise bibliographic references, analytical data and pooled results for samples derived using the Rb-Sr, SHRIMP, U-Pb, and Sm-Nd age determination methods.

Series Information

Lineage

These datasets are derived directly from Geoscience Australia's corporate Oracle OZCHRON database. Only data that is part of the current release of OZCHRON released in December 1999. <p>An ASCII extraction of the database is generated as ASCII comma-delimited files for each dating method that is part of the OZCHRON database release. <p>An MS ACCESS database format is also replicated from the ORACLE database and uses the same table structure. <p>The spatial representation of this database in (ArcView and MapInfo format) is extracted and generated using ArcInfo GIS software to meet the published data standard within the Geoscience Australia <a href="http://www.ga.gov.au/standards/datadict.html">data dictionary</a>. The extraction of the spatial GIS datasets is done within ArcInfo using advanced AML code (ORACOV.AML) developed by Dmitar Butrovski, Geoscience Australia.
