B.P. All the available regional paleo-magnetic data fit a two-phase rotation model, the first phase being an Eocene rotation that accompanied the accretion of the Oregon Coast Range to the continent and the second phase being a rotation associated with post–early Miocene extension in the Basin and Range province.
