Here we report the results of a pXRF analysis of obsidian stone artefacts from Here Sorot Entapa rockshelter (HSE) on Kisar Island in the Wallacean Archipelago. With the exception of a single flake, all the obsidian artefacts in this site are from a single source. Kisar has a metamorphic geology with fringing uplifted limestone terraces which makes obsidian raw material exotic to the island. The Kisar obsidian is a chemical match to obsidian of an unknown source previously recovered from sites in Alor Island to the west, and which also appears in Timor Leste to the south. The obsidian results suggest that Kisar was receiving exotic obsidian from ~15,000 years ago, and was linked with Alor and Timor in a maritime interaction network from at least 13,000 years ago.

基萨尔（Kisar），小岛国，在华莱士群岛拥有广泛的海上黑曜石网络

在这里，我们报告了从华莱士群岛的基萨尔岛上的Sorot Entapa岩石棚（HSE）的黑曜石假象的pXRF分析结果。除单个薄片外，该站点中所有的黑曜石文物均来自单一来源。基萨尔（Kisar）具有变质的地质，边缘有隆起的石灰岩阶地，这使得黑曜石原料对岛国具有异国情调。Kisar黑曜石与以前从西部亚罗岛的遗址中发现的未知来源的黑曜石在化学上相匹配，该黑曜石也出现在南部的东帝汶。黑曜石的结果表明，基萨尔（Kisar）从大约15,000年前就开始接受异国黑曜石，并且至少在13,000年前就已与海底互动平台Alor和帝汶建立了联系。
