Abstract
This GSQ-GA geochronology record presents a compilation of 16 new zircon U-Pb SHRIMP geochronological results from the Mount Isa and south Nicholson region, Queensland. This data was collected through the collaborative GSQ-GA geochronology project in August 2008 as part of the National Geoscience Accord (NGA) and in support of ongoing geoscientific investigations and regional geological mapping by the GSQ in the Mount Isa and south Nicholson regions. In addition, an appendix contains Sm-Nd whole rock analyses of selected samples. The acquisition of the Sm-Nd data in Appendix A was funded wholly by Geoscience Australia. A separate report for each sample is presented, which contain a brief geochronological interpretation as well as information on sample location and geological context. Three samples were analysed from the south Nicholson Basin from the WESTMORELAND and LAWN HILL 250K mapsheets, with an additional sample (Westmoreland Conglomerate) taken from the base of the Macarthur Basin. The twelve remaining samples were taken from various units in the greater Mount Isa region from the CLONCURRY, DOBYNN, DUCHESS, MOUNT ISA and URANDANGI 250K mapsheets. One sample was submitted for SHRIMP analysis but which failed to yield sufficient zircons for further investigation (rhyodacitic porphyry from within the Corella Formation).
