OZCHEM is Geoscience Australia's national whole-rock geochemical database. This release of OZCHEM contains over 50000 analyses of rocks, regolith and stream sediments from many regions of Australia. Each analysis includes a geographic location and a geological description, which includes the host stratigraphic unit, where known, and the lithology. Most samples have been collected by Geoscience Australia's field parties. OZCHEM is stored in an ORACLE relational database and is available in comma-delimited flat ASCII format. The data set is also bundled with documentation explaining the database structure and includes definitions of the database tables and columns (attributes).
