Interdisciplinary methodology for the characterisation of a temporary paleo-wetland in loma de Úbeda (Jaén, Spain)

Paleo-wetlands have fragmented in archaeological times associated with human stressors. We present an interdisciplinary analysis of a past temporary paleo-wetland located at an important junction between the valleys of the Rivers Guadalquivir and Guadalimar in the province of Jaén (Eastern Andalusia, Spain). We applied a high-resolution protocol to identify the paleo-wetland used for ritual purposes during the Iron Age. Based on archaeological excavations and analyses (soil micromorphology, pollen and phytoliths analyses, optically stimulated luminescence [OSL] datings, and other techniques), we found a palaeosoil formed in a wetland environment active during the Late Holocene, dating back to the 9th century AD.

古湿地（Paleo-wetland）在考古时期因人类活动胁迫因素而发生碎片化。本研究针对西班牙安达卢西亚东部哈恩省瓜达尔基维尔河（Guadalquivir）与瓜迪马尔河（Guadalimar）河谷交汇处一处已消亡的暂时性古湿地开展跨学科分析。我们采用高分辨率分析流程，对铁器时代用于仪式活动的该古湿地进行了识别。基于考古发掘与多维度分析手段（包括土壤微形态学、孢粉与植硅体分析、光释光（OSL）测年及其他相关技术），我们发现了一处形成于晚全新世活跃湿地环境中的古土壤（palaeosoil），其年代可追溯至公元9世纪。
