As an overall introduction to this session, this paper introduces our methodology for establishing ceramic provenance within the geologically complex Valley of Oaxaca. Natural clays have now been sampled from more than 300 locations throughout the valley, and their chemistry analyzed via INAA. Spatial averaging was used to create a series of smoothed contour maps showing how clay composition varies over space, and to generate a continuous reference grid of element concentrations against which...
