Mobility across the pre-Pyrenean mountain ranges during the Chalcolithic through strontium isotopes in human enamel: La Cueva de los Cristales (Sarsa de Surta, Huesca, Spain)

Abstract There is an increasing abundance in the archaeological record in Iberia for the Late Neolithic and the beginning of the Chalcolithic periods, mostly regarding burials. The higher pre-Pyrenean areas began to be settled more frequently, but the poor weather conditions have led researchers to suggest that human presence mostly took the form of sporadic visits. This argument has provoked substantial controversy given the increase not only in the archaeological artefacts recorded but also in the number of burial sites in less accessible places. To shed more light on the knowledge of these Chalcolithic mountain groups, we have carried out strontium isotope analysis of human enamel of ind…
