“…11,12), considered to be the basement and cover, respectively, of the former Iberian/ Europe margin of Neotethys (e.g. Ogniben, 1969Ogniben, , 1973Bouillin, 1984;Bouillin et al, 1986;Knott, 1987Knott, , 1988Dietrich, 1988;Dewey et al, 1989;Thomson, 1998). Thomson (1998), with fission track studies, demonstrates that the emplacement of continental basement rocks with Alpine metamorphism over ophiolitic rocks is constrained as a thrust contact of lower-to-middle Miocene age (<23 Ma), and the other major thrust contact of the diverse alpine basement units may be <18 Ma (Fig.…”
