THINKING ABOUT MOBILITY, DIET, AND SOCIAL CHANGE: ISOTOPIC ANALYSIS AT THE ARMACAO DO SUL SITE, FLORIANOPOLIS/SC/PENSANDO SOBRE MOBILIDADE, DIETA E MUDANCA SOCIAL: ANALISES ISOTOPICAS NO SITIO ARMACAO DO SUL, FLORIANOPOLIS/SC

There is an intensification in the processes of change associated with the shell-matrix sites of the Santa Catarina coast from 2000 BP onwards, marked by events such as the decrease in the number of sites, the decrease in the use of shells in their formation and the introduction of pottery. To better understand these changes, and taking the Armacao do Sul site (Florianopolis/SC) as a key element in this understanding, we performed strontium ([sup.87]Sr/[sup.86]Sr), carbon ([delta]13C) and nitrogen ([delta]15N) isotopic analyzes on the individuals buried there, together with the establishment of a stratigraphically referenced chronology. The results indicate that the processes of change occurred differently in different parts of the Santa Catarina coast and that, in the case of the Armacao do Sul site, the observed changes are related to an increased circulation and incorporation of individuals from different parts of the central coast and dietary change in male individuals.
