Development of a Unique Sourcing and Artifact Analysis Technique and Database for Dugway Proving Grounds in Utah, USA.

Using the Tracer III SD xrf laboratory system as a key component, a very precise and detailed methodology was developed for the elemental measurement, material type identification, and geological source location of artifacts found on Dugway Proving Grounds.Following 8 steps led to a very precise and accurate elemental analysis of the Dugway basalt and obsidian artifacts and sources in this study.
