In 2022, we released a Journal of Archaeological Science paper describing SourceXplorer, which is used for all sourcing-related projects at GeoArchaeo.
SourceXplorer allows researchers to apply sophisticated statistical procedures that generate robust and reproducible interpretations of relationships between sources and unknowns using any type of numerical data.
You can check out a deployed version of the app online for free at:
