The authors of this article (Birch et al. 2020) wish to correct the stated European copper association for an artifact from the Onondaga Barnes site (cat no. NYSM A2009.35K.99.28). The pXRF results could well be consistent with native copper. The Cu percent is slightly lower than for another copper artifact from the site (NYSM A2009.35K.99.42), but the other trace elements do not clearly suggest a European attribution. We thank James Bradley for bringing this matter to our attention.

北易洛魁遗址序列的精炼放射性碳年表：对合并、冲突和欧洲货物接收的影响 — 勘误

本文的作者（Birch 等人，2020 年）希望更正所声明的欧洲铜协会关于来自 Onondaga Barnes 遗址（目录号 NYSM A2009.35K.99.28）的人工制品。pXRF 结果很可能与天然铜一致。Cu 百分比略低于该地点的另一个铜制品 (NYSM A2009.35K.99.42)，但其他微量元素并未明确表明属于欧洲。我们感谢 James Bradley 提请我们注意此事。
