Summary of results. Joint NTGS-GA geochronology project: Arnhem Province, July 2014-June 2016

This Record presents new Sensitive High Resolution Ion Micro Probe (SHRIMP) U–Pb geochronological results from the Arnhem Province obtained between July 2014 and June 2016 during the Northern Territory Geological Survey–Geoscience Australia (NTGS–GA) geochronology project. Geoscience Australia’s contribution to this study forms part of the Exploring for the Future Programme, which aims to better understand the mineral, energy and groundwater resources of Northern Australia. Nine samples were analysed in support of ongoing regional geoscientific investigations and mapping programs by the NTGS. This Record documents results for each sample, and includes sample location and geological context, a description of the target mineral for geochronology, the relevant analytical data, and a brief geochronological interpretation. A summary of all results is presented in Table 1; the sample locations are shown in Figure 1. Full analytical data and interpretations for each sample, along with analytical session-specific details of the calibration data collected on the reference 238U/206Pb and 207Pb/206Pb zircons, are available via GA’s Geochron Delivery system (http://www.ga.gov. au/geochron-sapub-web/).
