Short summary
We present a field-based study of relay zone development using examples from the Koa’e fault system (Hawai’i) and the Krafla fissure swarm (Iceland). We show the evolution of second-order deformation within these zones and illustrate the effects of horizontal (heave) displacement gradients in evolving continental rift systems. Data are consistent with faults and intrusions from the Faroe Islands and E Greenland. We propose a new model for the evolution of segmented basins along the NE Atlantic.
