Obsidian finds from the Early Neolithic site at Grumăzești-Deleni (Neamț County)

The site of Grumăzești-Deleni (Neamț County) was excavated by Silvia Marinescu-Bîlcu during the late 1960s and 1970s. The excavations unearthed the remains of an Early Neolithic (Starčevo‐Criș) settlement, as well as traces of occupation during the Bronze Age (Komariv and Noua cultures) and the 3rd–4th centuries AD. The excavator’s field notes mention abundant obsidian finds associated with the Early Neolithic occupational layer. However, these original obsidian finds have been mislaid and were not available for analysis. During field surveys undertaken in the general area of the site in 2011 and 2017–2018, a further ten obsidian artefacts were recovered. Non‐destructive Energy Dispersive X‐ray Fluorescence (EDXRF) analysis of these new obsidian finds was undertaken using a Niton ‘XL3t ultra’ handheld portable XRF analyzer. Based on their geochemical and macroscopic characteristics they likely all originated in the Carpathian 1 source area.
