Identifying Archaeological Dacite and Andesite Sources in Southeastern Colorado

Summary

This is an abstract from the "SAA 2019: General Sessions" session, at the 84th annual meeting of the Society for American Archaeology.

Widely utilized raw stone material common in archaeological sites in southeastern Colorado has been determined to be a combination of dacite and andesite. Samples from two Sopris phase (1000-1200 CE) sites in southeastern Colorado were submitted for pXRF analysis to determine the mineralogical composition of the material. Archaeological dacite and its sources have been identified in areas west of the study area near the Taos Plateau; however, the material from both Sopris phase sites is from an unidentified source. This poster presents possible sources for the material as well as explores the importance of dacite as a raw stone material source in the region.
