A vast amount of ceramics (among other grave goods) were recovered from Castillo de Huarmey, a Wari culture (650–1050 ce) archaeological site on the north coast of Peru. In order to assess ceramic production area(s) and possible trade, political or cultural interactions with other regions, and to complement earlier petrographic analysis, electron microprobe analysis (EMPA) was conducted following a rarely used methodology in archaeology. The chemical composition of individual minerals in ceramics and sediments samples from the Huarmey Valley was obtained, focusing mainly on amphiboles, feldspars and pyroxenes. The results of the analyses clearly indicate that the majority of the ceramic analysed was made of raw material of local origin.

应用电子微探针分析确定秘鲁卡斯蒂略·德·休阿米的古代陶器生产的起源

从秘鲁北部海岸的瓦里文化（650-1050 ce）考古遗址卡斯蒂略·德·胡阿米（Castillo de Huarmey）回收了大量陶瓷（包括其他墓葬品）  。为了评估陶瓷生产区域以及与其他地区的可能贸易，政治或文化互动，并补充早期的岩相学分析，在考古学中很少使用的方法下进行了电子微探针分析（EMPA）。获得了Huarmey山谷陶瓷和沉积物样品中单个矿物的化学成分，主要集中于闪石，长石和辉石。分析结果清楚地表明，所分析的大多数陶瓷是由本地原材料制成的。
