An Isotopic Atlas of Australia

Multiple geochronology and isotopic tracer datasets have been compiled at continental scale and visualised in map view. The compiled datasets include Sm-Nd model ages of magmatic rocks; Lu-Hf isotopes from zircon; Pb isotopes from ore-related minerals such as galena and pyrite; U-Pb ages of magmatic, metamorphic and sedimentary rocks; and K-Ar and 40Ar-39Ar ages from minerals and whole rocks. A variety of maps can be derived from these datasets, which we refer to as an Isotopic Atlas of Australia. This ‘atlas’ provides a convenient visual overview of age and isotopic patterns reflecting geological processes that have led to the current configuration of the Australian continent, including progressive development of continental crust from the mantle (Sm-Nd; Lu-Hf), chemical and isotopic evolution in the source regions for mineralising fluids (Pb-Pb), magmatic and high-grade metamorphic reworking of the crust (U-Pb), and cooling and exhumation of the mid-crust (K-Ar; 40Ar-39Ar). These datasets and maps unlock the collective value of several decades of geochronological and isotopic studies conducted across Australia, and provide an important complement to other geological maps and geophysical images—in particular, by adding a time dimension to 2D and 3D maps and models.
