摘　　要：We report here new geochemical and geochronological data from mafic-ultramafic rock suites in the Ankara Mé1ange in north-central Turkey, and present a new tectonic model for its origin. Considered as one of most important relics of the Neotethyan realm in the region, the Ankara Mé1ange occurs between the Sakarya Continent （Eurasia） to the north and the Central Anatolian Crystalline Complex （CACC） to the south and includes remnants of the latest Triassic-early Jurassic Neotethyan oceanic lithosphere, fragments of Cretaceous seamounts,We report here new geochemical and geochronological data from mafic-ultramafic rock suites in the Ankara Mé1ange in north-central Turkey, and present a new tectonic model for its origin.
