Description:
This paper discusses the first geochemical characterization of obsidian fragments from the prehistoric site of
Roccapalumba (Palermo, Italy). The Neolithic age of the prehistoric settlement was constrained by pottery
and flint tools discovered in the same archaeological context. To define the provenance of the investigated
obsidian artifacts major and trace element analyses have been carried out by using scanning electron microscopy
(SEM–EDX) and inductively coupled plasma mass spectrometry (LA–ICP–MS). The comparison with
literature data of the Central Mediterranean source areas, based on trace elements content and their ratios
allow of constraining a provenance of the Roccapalumba obsidians from the Lipari Island. The obsidian lava
flow from Gabellotto Valley is the most probable source of volcanic glass at Lipari and also the most exploited
in the Mediterranean area for manufactured tools. The obtained results can contribute in reconstructing
the trade/exchange and procurement relationships occurred between the prehistoric human groups inhabiting
Sicily during Neolithic age.
