This technical report presents laser ablation-inductively coupled plasma mass spectrometry (LA-ICPMS) U-Pb zircon geochronology data for 15 rock samples derived from locations spread across the Gawler Craton. The purpose of the subject dating project was to provide a suite of dated zircons from the Gawler Craton from which Lu-Hf isotopic data can subsequently be collected [once finalised, the Lu-Hf isotopic data will be presented and discussed elsewhere]. The rocks that were sampled for dating are all igneous in origin. Metasedimentary rocks are not being addressed by the Lu-Hf isotopic study, since its purpose is to gain isotopic information about the nature of the growing Earth crust from which the sampled rocks were derived as a consequence of its partial melting during the Proterozoic. The samples analysed were obtained from legacy sampled rock material stored in the Geological Survey of South Australia, Department of State Development Drill Core Library. A number of the samples have previously been dated via sensitive high resolution ion microprobe (SHRIMP) U-Pb methods in the early 1990s, and the original SHRIMP I data that came from those samples are given in Fanning et al. (2007). The purpose of utilising the legacy material was to enable the efficient collection of zircon Lu-Hf data for many of the major rock units of the Gawler Craton. Zircons from the samples were first analysed for their U-Pb isotopic composition in order to ensure that the Lu-Hf isotopic data can be compared with certainty against a U-Pb age. Knowledge of the U-Pb isotopic age of a zircon is important when interpreting the Lu-Hf isotopic data for a given zircon crystal, and hence sample. All of the LA-ICPMS U-Pb isotopic data from this dating project are presented in an appendix. As herein interpreted, they indicate that the samples predominantly fall into the age range c. 2000–1710 Ma; however, most samples are from the c. 1790–1710 Ma time interval. The latter time interval represents one during which the Gawler Craton was undergoing active sedimentation, with the formation of widespread basin systems across the region, from the Hutchison Group in the southern Gawler Craton to sedimentary rocks now preserved as granulite facies gneisses in the northern Gawler Craton and western Gawler Craton (Daly et al. 1998; Fanning et al. 2007; Hand et al. 2007; Reid and Hand 2012).
