Establishing an Ecuadorian Isoscape: The Importance of Baseline Strontium Data in a Volcanic Landscape. [PDF]

open access: yesAm J Biol Anthropol
ABSTRACT Objectives Strontium isotopes (87Sr/86Sr) have been used worldwide to track migrations and identify nonlocal individuals in the past. In South America, these studies often use comparative baseline maps, or isoscapes, established by samples from archaeological fauna and geologic formations. However, baseline research has focused on coastal Peru
