Large-Scale Patterns in the Chemical Composition of Mississippian Pottery

Abstract

Neutron activation analysis of Mississippian sherds from 21 regions across the Southeast has revealed the existence of distinctive chemical groups that are associated with four large geographical areas. One such group is associated with sites along the Mississippi River and its western tributaries, a second is associated with sites on the Appalachian Rim in Tennessee, a third is associated with sites on the Piedmont and associated drainages, and a fourth is associated with sites in Alabama. This pattern reflects the existence of several large, clay-mineral provinces in the Southeast that now can be recognized as sources in future studies of long-distance exchange.
