This paper proposes an archaeometric contribution to the study of the Inca pottery style from the southeastern frontier of Tawantinsuyu, also known as the Inca Empire, located in Central Western Argentina (CWA). In complementing previous research, a geochemical and mineralogical characterisation of ceramics from various Inca and local sites is carried out by combining X-ray fluorescence analysis (WD-XRF), powder X-ray diffraction analysis (PXRD) and scanning electron microscopy (SEM-EDX). The exhaustive statistical treatment and discussion of the chemical data, complemented by mineralogical and microstructural data gathered through PXRD and SEM-EDX techniques, provide significant insights into the provenance of raw materials, paste recipes, firing conditions, estimated firing temperature and post-depositional contaminations. A complex structure comprising six meaningful ceramic groups has been identified, with some of them attributed to hypothetical provenance areas defined by previous research. Additionally, many ceramics remained ungrouped. Despite the identified compositional variability, certain technological attributes exhibit a higher degree of homogeneity. The estimated firing temperature and microstructure of the pottery denote some control over firing conditions to produce vessels with high mechanical strength and toughness suitable for storage and short-distance distribution. The results of both compositional and technological analyses point to the existence of multiple production loci within a domestic or communitarian model of production sharing the same pottery tradition.

本文提出了对位于阿根廷中西部（CWA）塔万丁苏尤（也称为印加帝国）东南边境印加陶器风格研究的考古学贡献。为了补充之前的研究，通过结合 X 射线荧光分析 (WD-XRF)、粉末 X 射线衍射分析 (PXRD) 和扫描电子显微镜 (SEM-) 对来自印加和当地遗址的陶瓷进行了地球化学和矿物学表征。 EDX）。对化学数据进行详尽的统计处理和讨论，辅以通过 PXRD 和 SEM-EDX 技术收集的矿物学和微观结构数据，为原材料来源、浆料配方、烧制条件、估计烧制温度和沉积后污染提供了重要见解。已经确定了由六个有意义的陶瓷组组成的复杂结构，其中一些归因于先前研究定义的假设来源区域。此外，许多陶瓷仍未分类。尽管已确定成分存在差异，但某些技术属性表现出更高程度的同质性。陶器的估计烧制温度和微观结构表明对烧制条件进行一定的控制，以生产具有高机械强度和韧性的容器，适合储存和短距离分配。成分分析和技术分析的结果表明，在共享相同陶器传统的家庭或社群生产模式中存在多个生产地点。
