| Abstract: | K-Ar dating on separated minerals from the infra-peridotitic metamorphic soles outcropping beneath various eastern Mediterranean ophiolite complexes (Pindos nappe in Greece; Lycian, Antalya, Beysehir-Hoyran, Mersin and Pozanti-Karsanti nappes in the Taurides belt. Turkey; Baër-Bassit nappe in Syria) shows that the main metamorphic recrystallization of those rocks occurred 25–30 m.y. prior to the tectonic emplacement of the ophiolite complexes onto a continental platform. These data support the hypothesis of an early slicing of the oceanic crust before its obduction, advocated recently by several authors. |
