In the Late Neolithic necropolis of Galliano (Taranto, Southern Italy) 52 samples of obsidian artefacts were found. Their characterization by absolutely non-destructive techniques like WD-XRF and SEM-EDS, for almost all of the samples, recognized the Lipari source for the raw material. Two samples show a different origin area: one from Palmarola, the southernmost signalling in Puglia for this source, and one from Pantelleria (sub-source of Salto la Vecchia and Balata dei Turchi) as first signalling on the continental Italy. Both source area, Palmarola and Pantelleria, have also been safely ascertained through quantitative compositional analyses of the microphenocrysts (pyroxenes and feldspars) present in the glass of 27 and 42 obsidian samples. In particular, the discovery of obsidian from Pantelleria in the Late Neolithic necropolis of Galliano, which can be traced back to the first centuries of the second half of the fifth millennium BC, significantly expanded its distribution area towards the east and the north, in a chronologically well-defined context.

在新石器时代晚期的加利亚诺墓地（意大利南部塔兰托），发现了 52 个黑曜石文物样本。他们通过绝对无损技术（如 WD-XRF 和 SEM-EDS）对几乎所有样品进行表征，确认了原材料的 Lipari 来源。两个样本显示了不同的起源区域：一个来自 Palmarola，这是普利亚最南端的信号源，另一个来自 Pantelleria（Salto la Vecchia 和 Balata dei Turchi 的子源），作为意大利大陆的第一个信号源。通过对 27 个和 42 个黑曜石样品的玻璃中存在的微斑晶（辉石和长石）进行定量成分分析，还安全地确定了源区 Palmarola 和 Pantelleria。特别是在新石器时代晚期的加利亚诺墓地发现了来自潘泰莱里亚的黑曜石，
