Summary:Within the Dingle Peninsula ORS succession, the Inch conglomerate formation contains metamorphic clasts derived locally from a basement high thrust up along the Dingle Bay lineament during the Middle Devonian. Tourmaline, which occurs in quartz-tourmaline veins, banded tourmalinites and tourmaline pegmatites within the clasts is similar in composition and zoning trends to that from SE Ireland, but different to that from N Connemara. These data, together with evidence from petrology and geophysics, suggest that the metamorphic basement block beneath the Dingle basin is similar to the pre-Caledonian basement lithologies of SE Ireland, rather than the Connemara metamorphic complex. EPMA results are given for cores and rims of eight schorl-dravites. [J.F.]
