This Record presents new zircon U-Pb geochronological data, obtained via Sensitive High Resolution Ion Microprobe (SHRIMP), for 12 samples of igneous rocks from central and southern New South Wales, as part of an ongoing Geochronology Project conducted by the Geological Survey of New South Wales (GSNSW) and Geoscience Australia (GA) under a National Collaborative Framework agreement. Eight samples were selected to better understand the geological evolution and mineralisation history of areas prioritised for investigation by the MinEx Co-operative Research Centre (MinEx CRC) under its National Drilling Initiative (NDI) program. Three samples are from the northern Molong Volcanic Belt east of Dubbo (‘MXDU’), and five are from the eastern Lachlan Orogen near Forbes (‘MXFO’). The remaining four samples are from the central Lachlan Orogen in southern NSW, in support of GSNSW’s East Riverina mapping program (‘ERIV’). The results herein correspond to U-Pb SHRIMP zircon analyses undertaken by the GSNSW-GA Geochronology Project during the July 2020–June 2021 reporting period. All quoted uncertainties are 95% confidence intervals.
