This article presents the ceramic sequence and chronology resulting from a multi-year program of survey, excavation, and analysis of pre-Hispanic settlement and exploitation within the Zinapécuaro-Ucareo (“U-Z”), Michoacan obsidian source area. Pottery analysis and classification aided by seriation analysis identified nine ceramic complexes and seven ceramic phases and sub-phases that both expand and refine the ceramic sequence previously established for the region by Gorenstein's (1985) investigations at nearby Acámbaro, Guanajuato. Initially established by ceramic cross-dating, the U-Z ceramic chronology has been largely confirmed by 30 radiocarbon dates and spans over 2,000 years of pre-Hispanic settlement, which included at least two notable episodes of trait-unit and site-unit intrusion from the eastern El Bajío and central Mexico. One of these episodes involved the appearance of two enclaves settled by individuals from the Acambay valley c. 90 km to the East, most likely from the site of Huamango, which our data indicate would have been occupied during the Middle Postclassic period.

本文介绍了米却肯黑曜石产地 Zinapécuaro-Ucareo (“UZ”) 内西班牙前定居点和开发的多年调查、挖掘和分析计划所产生的陶瓷序列和年代学。在系列化分析的帮助下，陶器分析和分类确定了 9 个陶瓷复合体和 7 个陶瓷阶段和亚阶段，它们扩展和完善了先前由 Gorenstein（1985 年）在附近的瓜纳华托州 Acámbaro 进行的调查为该地区建立的陶瓷序列。乌兹别克斯坦陶瓷年代学最初由陶瓷交叉年代确定，已在很大程度上得到 30 个放射性碳年代的证实，跨越 2,000 多年的前西班牙定居点，其中包括至少两个显着的特征单位和地点单位从东部入侵的事件El Bajío 和墨西哥中部。其中一个事件涉及两个飞地的出现，这些飞地由来自 Acambay 山谷的个人定居。向东 90 公里，最有可能是从 Huamango 遗址开始，我们的数据表明该遗址在后经典中期可能已被占领。
