Research at prehispanic obsidian sources offer great potential for contributing to the reconstruction of ancient patterns in interaction and production. While all archaeological research is cumulative, quarry research is especially so because every artifact that is sourced contributes to a better understanding of the entire configuration of production and interaction. Therefore one can expect increasing focus upon, and more significant results from research into raw material source areas as archaeological knowledge accumulates. One should also anticipate rapid improvements in the sourcing and knowledge of particular raw materials as technical equipment become more affordable.
