LATE TRIASSIC (CARNIAN) UNCONFORMITY IN A BLOCK OF THE LATEST CRETACEOUS VOLCANIC OLISTOSTROME UNIT IN THE IZMIR-ANKARA ZONE

In a huge block within the Latest Cretaceous volcanic olistostrome Unit in the Izmir-Ankara zone, nonmetamorphic epidastic and carbonate Late Triassic (Carnian) strata rest unconformably on metacarbonate. Abundant sand-sized detritus of serpentinite occur in the Late Triassic strata. The unconformity is comparable, with respect to stratigraphic setting, with that in the northerly-lying Late Triassic turbidite-olistostrome zone, between the low-grade metamorphic basement and the Late Triassic sedimentary cover.
