Abstract: Paquimé is a remarkable pre-Hispanic settlement that flourished between the 13th and 15th centuries in northwest Chihuahua, Mexico. This site is recognized for its distinctive fusion of Mesoamerican and Southwestern American cultural traits. Although much of the explanatory models about this settlement’s development and regional role have focused on trade, pottery from the Salado tradition, particularly Polychrome Gila and Polychrome Tonto, has generally been presumed to have originated in the American Southwest. To confirm the interaction between both cultures and contribute to the clarification of the absolute chronology of Paquimé, the geochemical characterization and rock-magnetic characterization of sherds of local and presumably foreign manufacture were carried out, including sherds with manufacture that seems to be the result of the abovementioned relationship. SiO2 and Al2O3 contribute more than 75% to the observed variation. The Casas Grandes pottery shares the geochemical signatures of both local and foreign types. High-coercivity magnetic grains dominate in the foreign-type pottery samples. In contrast, relatively low-coercivity ferrimagnetic grains are the main features of local-type sherds. Essentially similar absolute intensity values were obtained for both potsherd wares. The most probable age intervals obtained for all ceramic samples studied range from 990 AD to 1310 AD, in agreement with previous surveys and local archaeological frameworks.
