Geochemical analyses of stone artifacts reveal long-distance voyaging among Pacific Islands during the last millennium ScienceAdvances
In order to better understand the relationship between these Polynesian societies of the western Pacific, Melanesia and Micronesia—often referred to as"Polynesian Outliers"—a multidisciplinary team of researchers analyzed the geochemical signature of stone artifacts collected in Vanuatu, the Solomon Islands and the Caroline Islands between 1978 and 2019.
Adzes are versatile cutting tools comparable to axes. Among the eight adzes or adze fragments the researchers analyzed, six were sourced to the same large fortified quarry complex of Tatagamatau on Tutuila Island , which is located more than 2,500 kilometers away in the Polynesian homeland. "Tatagamatau adzes were among the most disseminated items across West and East Polynesia, and the sourcing of Taumako and Emae adzes suggest bursts of long-distance mobility towards the Outliers similar to those that led to the settlement of East Polynesia," says lead author Aymeric Hermann, researcher at Centre National de la Recherche Scientifique and associate researcher at the Department of Linguistic and Cultural Evolution at the Max Planck Institute for Evolutionary Anthropology.
The geochemical investigation of stone artifacts from the Polynesian Outliers also provides critical information on inter-island transfers between the Polynesians and their neighbors in the western Pacific, specifically between the Banks Islands and Central Vanuatu, and between the Bismarck and the Caroline Islands.
"A recent study describes an obsidian stemmed point as a chiefly heirloom found on Kapingamarangi Island with a geochemical signature matching an obsidian source on Lou Island in the Admiralties: this is an exciting find that echoes our identification of a basalt flake from mainland New Britain on that same atoll," adds Hermann.
