Accretion and exhumation structures formed by deeply
[1] The Lower Cretaceous Iwashimizu complex in the southern Kamuikotan zone Japan was formed by accretion of seamounts which subducted to the lawsonite albite to blueschist facies The complex is a pile of four nappe units Each unit comprises a duplex with horses of seamount volcanics ± sedimentary rocks and ramp shear zones suggesting a thin skinned peeling of subducted seamounts
