This report book contains a compilation of zircon and monazite U-Pb geochronological data, plus geochemical data, that are derived from the Fowler Domain of the Gawler Craton. The related study has been undertaken as part of the Australian Research Council and Primary Industry and Resources South Australia (PIRSA) co-funded Linkage Grant (LP0454301): "Developing a Tectonic Framework for the Gawler Craton: Paving the Way for Successful Mineral Exploration". The aim of this study is to provide constraints on the depositional ages and provenance of metasedimentary units, as well as providing direct geochronological constraints on the timing of deformation and metamorphism from the poorly exposed and little studied western Gawler Craton, with the view to developing a coherent model of the tectonic setting and evolution of the Fowler Domain. This is a technical report describing samples analysed and presenting the analytical results obtained, augmented by a brief discussion of their geochronological interpretation. The data form part of the primary author's Ph.D studies at the University of Adelaide, and therefore their broader geological interpretation and implications will be discussed at length in later publications. Due to the extremely limited exposure of basement lithologies in the western Gawler Craton, all of the samples with analyses presented here were obtained from drill core stored at the PIRSA Core Library in Adelaide. Because of the limited amount of core available for sampling, sample sizes are correspondingly small, limiting the number of analyses that were able to be obtained.
