Clay Sources, Pottery Production, and Regional Economy in Chalchihuites, Mexico, A. D. 200-900

Pottery and clays from the Chalchihuites region of northwestern Zacatecas are characterized to examine ceramic production and exchange among settlements between A. D. 400 and 900. Instrumental neutron activation and petrographic analysis of 134 pottery and 26 clay samples from three Chalchihuites ceremonial centers identify pottery made from local clays and distinguish pottery found at each center that was not made from local clay deposits. Residents of Alta Vista, the region’s main center, acquired an elaborate painted ware from a second center located 30 km away after A. D. 650. The ceramic compositional data provide a basis for understanding the distance and direction that pottery was exchanged in Chalchihuites as economic activities increased in the region.
