Do obsidian sources in the same region share a similar chemical signature?
If a two different pieces of obsidian have a similar, but not identical, chemical signature when measured with pXRF, is it likely that they are from a similar region?
To ask the question in the negative: is there a chance that obsidian sources from opposite sides of the world may happen to have a similar chemical signature?
