Abstract
Abstract The ancient Andeans, who lived along the coastal region of the arid Atacama Desert in present day Chile had access to scarce freshwater via a few small rivers originating from the Andean Altiplano. Due to volcanic-derived lithium minerals and their solubility in water, the surface water in the Atacama Desert region is rich with lithium (Li); often many orders of magnitude higher than that of other rivers in the world. The goal of this study was to examine whether ancient Andean mummy individuals (n = 145) from four burial areas in northern Chile (Azapa, Camarones, Lluta and Morro) were exposed to geogenic lithium by conducting laser ablation-inductively...
