The objective of this study is to better understand how people gained resources to make Middle and Late Woodland pottery from Sipiwesk Lake in northcentral Manitoba. To meet this objective, we conducted petrographic analyses of sediments from Sipiwesk Lake, archaeological sherds from sites around the lake, material from outwashes, fired experimental tiles, and sherds from archaeological sites across the boreal forest ecozone and the prairie ecozone in the south-central and south-western regions of the province. Specimens from each sample were examined using optical petrography, X-ray diffraction, and scanning electron microscopy. Nine distinct fabrics (fired pastes) were identified by correlating the results of these analytical techniques. Each fabric can be considered a “paste recipe” that has local, regional, or pan-regional distributions. Local and regional distribution patterns redefine what “local” production means for mobile hunter-gather communities when the distances people travel for regular and routine seasonal activities are considered. This new model challenges exchange as an explanation for the spatial distribution of pottery. Expanding the range of exploitable distance thresholds for resource acquisition is alone enough to explain why the same pottery compositions would be found over vast areas incorporating one or more river systems. We further suggest that pan-regional recipes resulted from similar practices that served to add, remove, and/or alter the properties of nonplastics in clays. Such practices could potentially frustrate pottery provenience analysis, and we urge further research on the production of experimental pastes and the application of geochemical analyses to precontact Manitoba pottery.

确定加拿大马尼托巴北部北方森林中的预接触陶瓷资源区

这项研究的目的是更好地了解人们如何从马尼托巴省中北部的 Sipiwesk 湖获得资源来制作中晚期林地陶器。为实现这一目标，我们对来自 Sipiwesk 湖的沉积物、湖周围遗址的考古碎片、来自冲洗的材料、烧制的实验瓦片以及来自北方森林生态区和中南部草原生态区的考古遗址的碎片进行了岩相分析。和该省的西南地区。使用光学岩相学、X 射线衍射和扫描电子显微镜检查来自每个样品的样品。通过关联这些分析技术的结果，确定了九种不同的织物（烧制浆糊）。每种织物都可以被视为具有局部、区域或泛区域分布的“糊剂配方”。当考虑到人们为定期和例行的季节性活动而旅行的距离时，本地和区域分布模式重新定义了“本地”生产对于流动狩猎采集社区的意义。这种新模型挑战了作为解释陶器空间分布的交换。扩大资源获取的可开发距离阈值的范围就足以解释为什么在包含一个或多个河流系统的广阔地区会发现相同的陶器成分。我们进一步建议泛区域配方源于类似的做法，这些做法用于添加、去除和/或改变粘土中非塑料的特性。这种做法可能会阻碍陶器来源分析，
