COMMENT Comment on ‘Tectono-sedimentary evolution of lower to middle Miocene halfgraben basins related to an extensional detachment

temperature metamorphic unit on the island of Crete occurred between c. 24– 21 and c. 10 Ma (Jolivet et al., 1996; Thomson et al., 1998; van Hinsbergen and Meulenkamp, 2006). This exhu-mation process has been suggested to have occurred partly syn-orogenically by e.g. extrusion or buoyant rise within a subduction channel and partly post-orogenically by N–S extension (Thomson et al., 1998; Jolivet et al., 2003; Rahl et al., 2005).
