Evolution of Migrating Transform Faults in Anisotropic Oceanic Crust: Examples from Iceland
Major transform fault zones link extensional segments of the North American – Eurasian plate boundary as it transects the Iceland Hotspot. Changes in plate boundary geometry, involving ridge jumps, rift propagation, and related transform fault zone migration, have occurred as the boundary has moved...
