Provenance of obsidian artifacts from the Wolseongdong Paleolithic site, Korea, and its archaeological implications
Quaternary International(2018)
摘要
The provenance of obsidian artifacts from the Wolseongdong Paleolithic site in Korea has hitherto been uncertain. A previous study was unable to identify the source despite the availability of major/minor element concentrations, strontium isotopic composition, and K–Ar age. We have revisited the problem, and obtained geochemical data for 100 obsidian artifacts from Wolseongdong using Laser Ablation – Inductive Coupled Plasma – Mass Spectrometry (LA–ICP–MS). It was found that all lithics originated from a single source located around 700 km away, at the Paektusan Volcano on the DPR Korea/Chinese border. Our findings highlight the necessity of reliable data analysis and quality assurance for obsidian characterization studies.
