Reference obsidian specimens for provenance analysis

Reference obsidian specimens are defined for each discriminant (compositional) group and are used to assign archaeological obsidian to these groups. Each discriminant group is represented by a set of 12 reference specimens, for which WDXRF compositional data are also available. The Japanese Obsidian Database provides information on discriminant groups in each region from Kyushu to Hokkaido, as well as their distribution and the localities associated with each group.
