Unravelling the formation processes and depositional histories of the Middle Palaeolithic Ararat-1 Cave, Armenia: A multiscalar and multiproxy geoarchaeological approach

The sedimentary sequence of Ararat-1 Cave encapsulates an intricate depositional archive (Marine Isotope Stage 3), crucial for our understanding of the Middle Palaeolithic in the Armenian Highlands and beyond. The study of this record is accomplished through the use of a multi-proxy geoarchaeological framework of analysis, incorporating stratigraphical, micromorphological, sedimentological, mineralogical, chemical, magnetic, micro-archaeological and geochronological methods. These analyses demonstrate the predominance of geogenic processes, including rockfalls, grain and debris flows, interbedded with aeolian sedimentation, as well as localised pyroclastic material in-wash events. Post-depositional alterations are primarily linked to intense bioturbation, as well as minimal karst-induced cementation and minor phosphate diagenesis. The study of the anthropogenic and biogenic records indicates dynamic human-animal habitation histories. Human visits, associated with combustion and consumption activities, were infrequent and short-lived, representing brief occupation episodes in a cave habitually visited by carnivores and herbivores. This high-resolution reconstruction of Ararat-1 Cave formation histories improves our understanding of regional settlement and mobility patterns, highlighting the presence of Middle Palaeolithic groups that temporarily camped in the Ararat Depression.
