Geological Survey of Queensland and University of Queensland, School of Earth Sciences Theses Geochemistry and Geochronology Databases.

Abstract

These databases are the product of a collaborative project between The University of Queensland and the Geological Survey of Queensland. It is funded by the Queensland Government through the Queensland's Smart Mining - Future Prosperity program. These databases contain: 1. Records of all theses submitted by Earth Sciences students over the past 70 years. 2. The Access Geochronology and Geochemistry database contains thesis title, author, date submitted, supervisor, and area studied; Sample numbers, specimen localities (map coordinates), rock type, unit, description, depth (if from borehole data), precision of locality and thesis reference; geochemical data (elemental or oxide abundances) and analytical limits (precision and detection limits for analytical method used), as well as the instrumentation used for each analysis (XRF, ICP-OES, ICP-MS etc); isotope geochemistry (with analytical limits indicated); and geochronological results (age, methodology, with analytical limits indicated). 3.Two Excel databases are also provided which, together, provide all the information available in the Access database. 4.This website also contains, in separate folders, ArcGIS and MapInfo files containing tables and maps displaying the locations of the study sites and the localities of individual samples taken for each thesis. Each icon represents a sample locality. Information embedded within each locality icon includes the author, title of the thesis, date, and various analytical results. 5. Please note: Browser windows in the MapInfo and ArcGIS files fill empty cells with zeros. This may give rise to the erroneous impression that certain elements may be present at very low concentrations while in fact there have been no analyses for those elements at all. Users are advised to check null values in the databases. 6. Recently, a new (limited) database containing mineral chemistry, with accompanying digital maps have also been included, with a similar structure as the geochemistry and geochronology databases.
