Compared to elsewhere in Oceania, the history and character of stone axe‐adze production and exchange in the Bismarck Archipelago is very poorly known. To explore the feasibility of using geochemical analysis to trace past social interaction, we conducted a non‐destructive portable XRF study of 97 ground stone artefacts from archaeological contexts in New Britain and the ethnographic collection at the Australian Museum. The study capitalised on the well‐documented spatial distribution of geochemical variation resulting from the plate‐tectonic history of the region. The results indicate that prehistoric communities in New Britain specialised in goods such as ground stone tools or obsidian in order to facilitate social interaction over a large region.

探测巴布亚新几内亚新不列颠的交换网络：斧状突刃和原位火山岩源之间的地球化学比较

与大洋洲的其他地区相比，the斯麦群岛的石斧结石生产和交换的历史和特征鲜为人知。为了探索使用地球化学分析来追溯过去的社会互动的可行性，我们对来自新不列颠考古背景和澳大利亚博物馆的人种学收藏品的97种地面石器物进行了无损便携式XRF研究。该研究利用了该地区板块构造历史所产生的有据可查的地球化学变化的空间分布。结果表明，新英国的史前社区专门从事诸如石材工具或黑曜石之类的商品的开发，以促进大区域的社会互动。
