摘要

•Relative XRD peak intensities are used as discriminatory variables.•An early exploratory map of topsoil mineralogy in/around Canberra, Australia.•Mineralogy can be useful to spatially discriminate elementally similar locations.•Distribution of provenance values useful to indicate non-representative samples.•Combining mineralogy and elemental-based predictions improved precision.
