概要	Ceramic typology is the systematic classification of pottery into named groups — wares, types, and varieties — on the basis of shared attributes of form, fabric, surface treatment, decoration, and manufacturing technology. Because pottery is durable, ubiquitous, and changed rapidly in style, it is the archaeologist's most powerful tool for ordering sites and layers in time and for linking material to cultural traditions. As Prudence Rice's standard sourcebook sets out, a typology is built by recording consistent attributes, partitioning the assemblage into defined types, and arranging those types in a nested hierarchy that can then be quantified and compared across contexts. The resulting type frequencies become the raw material for relative dating, seriation, and the interpretation of trade, identity, and chronology.	NAA provenance is the use of instrumental neutron activation analysis (INAA) to determine where archaeological ceramics, obsidian, and other materials were made or obtained, by exploiting their high-precision multi-element chemical fingerprints. INAA irradiates a sample with neutrons, making its elements briefly radioactive, and measures the characteristic gamma rays they emit to quantify the concentrations of roughly thirty elements, including many trace and rare-earth elements at very low levels. As Glascock and Neff describe in their account of the technique's role in archaeology, the analytical power of NAA lies less in the measurement itself than in what follows: the statistical formation of compositional groups and the assignment of artifacts to those groups and to geological or production sources. This entry focuses specifically on that provenance application — building compositional groups and attributing artifacts by Mahalanobis distance — rather than on the instrumental measurement in general.
