The Achaea and Corinth regions of the northern Peloponnese are renowned for their rich archaeological record. Achaea is part of mainland Greece in the North-Western Peloponnese, whereas Corinth is in the North-Eastern Peloponnese. Since ancient times, ceramic production has played an important role in the local and regional social and economic evolution in both regions. Our aim is to identify and evaluate sources of clayey raw materials outcropping in the territory of the northern Peloponnese, potentially used for ceramic production during antiquity, by means of their compositional and technological properties. This was accomplished by the systematic sampling of clayey raw materials from a wide area spanning the Northern Peloponnese. In spite of the inter-regional chemical homogeneity recorded in their geochemical analysis in terms of major, minor, and trace elements, the data obtained led to their intra-regional compositional distinction into calcareous, calcareous-dolomitic, and siliceous clayey sediments. In addition, the presence of the clay minerals (illite, chlorite, smectite, mixed phases), their granulometry, and their bulk mineralogy all proved to considerably influence some of their performance characteristics, such as their plasticity. After a full characterization of the studied material, the clay deposits in all areas did not show significant differentiations, but they did need improvement to be suitable for the production of ceramic artifacts.

伯罗奔尼撒北部的Achaea和Corinth地区以其丰富的考古记录而闻名。亚该亚是伯罗奔尼撒西北部希腊大陆的一部分，而科林斯则位于伯罗奔尼撒东北部。从远古时代开始，陶瓷生产就在两个地区的地方和地区社会经济发展中发挥了重要作用。我们的目标是通过其成分和技术特性，识别和评估伯罗奔尼撒北部地区出土的黏土原料来源，这些物质可能在上古时期用于陶瓷生产。这是通过对跨越伯罗奔尼撒半岛的广阔地区的黏土原料进行系统采样来实现的。尽管在地球化学分析中记录的区域间化学均一性主要，次要，和痕量元素，获得的数据导致其区域内的成分区分为钙质，钙质-白云质和硅质黏土沉积物。另外，粘土矿物（伊利石，绿泥石，蒙脱石，混合相）的存在，其粒度和其整体矿物学都被证明会极大地影响其某些性能特征，例如可塑性。在对研究材料进行全面表征后，所有区域的粘土沉积物均未显示出明显的差异，但确实需要改进以适合于生产陶瓷制品。混合相），粒度和整体矿物学都被证明会极大地影响其某些性能特征，例如可塑性。在对研究材料进行全面表征后，所有区域的粘土沉积物均未显示出明显的差异，但确实需要改进以适合于生产陶瓷制品。混合相），粒度和整体矿物学都被证明会极大地影响其某些性能特征，例如可塑性。对所研究材料进行全面表征后，所有区域的粘土沉积物均未显示出明显的差异，但确实需要改进以适合于生产陶瓷制品。
