Temporal Data Requirements, Luminescence Dates, and the Resolution of Chronological Structure of Late Prehistoric Deposits in the Central Mississippi River Valley

Our ability to order chronologically the archaeological record has long been linked to our capacity to generate explanations. Evolutionary explanations make even greater demands on chronological data requirements than most other approaches. Single date characterizations of deposits are wholly inadequate. Rather, we require distributions of dates that can be used to estimate duration and rates of assemblage formation. In addition, the events dated must have direct archaeological relevance such as artifact manufacture or deposition. In a study of the evolution of social complexity in the late prehistoric record of the central Mississippi River valley, luminescence dates of sherds that have been assigned to a single culture historical type provide a means of determining the chronological character of assemblages derived from large village deposits. In this way, the temporal data requirements for evolutionary accounts can be met reliably.
