There And Back Again: A Geochemical Analysis of Casas Grandes Shell Procurement and Exchange
Previous studies of shell exchange in the Southwest have supported archaeological interpretations of competing regional networks in which the Hohokam, Sinagua, and Anasazi acquired shell from the Gulf of California, while the Casas Grandes, Mimbres, and Western Puebloan groups acquired shell from West Mexico. This study will build on previous analyses by integrating stylistic analysis with an expanded compositional database to further examine the role of shell exchange in the Animas phase region of New Mexico and Arizona. ICP-MS analyses of shell artifacts from 76 Draw will be combined with modern shell and an expanded Casas Grandes geochemical dataset to investigate potential regional sources for shell procurement. The geochemical analysis of shells from 76 Draw, as well as other Animas phase and Casas Grandes samples, will provide a clearer picture of exchange and interactions between the Casas Grandes core and sites in the borderlands.
