Popis: Seventy-three Neolithic polished stone artefacts of the S. Lazzaro di Savena collection, of which about half petrographically studied, show both Early and Middle Neolithic Age. Sixty-five artefacts (89 %) are manufactured with HP-metaophiolites (“greenstone”): Alpine Eclogites (71 %), Na-pyroxenitic Jades (11 %), Omphacite schists (3 %) and Glaucophanic schists (4 %), similar to all Neolithic collections from Northern Italy. Some petrographic peculiarities suggest a provenance from the Rivanazzano or nearby sources in the NW-Apennines. Of eight other finds (11 %), four adzes and one fragmented arm ring are manufactured with basaltic lithologies derived from the Apennine ophiolites cropping out in the S. Lazzaro area. They demonstrate local sources and ability of manufacturing in loco. A few analogous Early Neolithic implements near the Po River and west of Bologna reveal a so far unknown circulation of these lithologies. One chisel made in sandstone comes from a nearby source. Two limestone arm ring fragments probably derive from SE, i.e. from the Ripoli Culture.
