The use of instrumental neutron activation analysis (INAA) in ceramic research in the American Southwest has become widespread over the last ten years. This volume presents case studies of Southwestern ceramic production and distribution in which INAA is used as the primary analytical technique. These studies use provenance determination to explore such issues as exchange, migration, social identity, and economic organization. Case studies from the Southwestern periphery provide a comparative perspective from which to view the range of variation in Southwestern ceramic circulation patterns. Several of the case studies use mineralogical approaches to supplement chemical sourcing data. And, a case study using petrographic analyses provides a counterpoint to the emphasis on chemical approaches (INAA) in this volume. This volume documents the cumulative contribution of INAA-based ceramic characterization to knowledge of the prehistory of the Southwest.
