摘要：Petrographic and chemical analysis of prehistoric ceramic sherds from the island of Carriacou in the southern Grenadines, West Indies offers preliminary insight into resource exploitation, manufacturing techniques, and the distribution of pottery from ca. AD 400¨C1200. Thin-section petrography of two different suites of sherds (Suite 1: n=24 from six sites; Suite 2: n=54 from five of the same sites plus three others) indicates that there are at least five temper groups, all or most of which appear to be exotic to Carriacou. Instrumental neutron activation analysis (INAA) of 56 sherds from Suite 2 reveals the existence of two main geochemical compositional groups. This may be a reflection of prehistoric potters selecting clays derived from two geo-chemically different substrates in the location(s) of manufacture. A comparison of these find-ings suggest that: 1) exotic materials are predominant in manufacture; 2) both local and re-gional transport of ceramics occurred prehistorically; 3) the correspondence between the tem-per and INAA compositional groups is unclear, suggesting that the paste geochemistry might mask minor temper differences; and 4) clay and temper preferences may have changed through time, although this will require further testing
