 Some research using new plate motion data gathered from hotspot reference frames from around the world suggests that the Iceland hotspot's path differs from that estimated from older investigations.Many older rocks (dated 75–70 Ma) located throughout the area to the west are not only located near hypothesized Iceland hotspot paths but are also attributable to hotspot volcanism.This implies that the Iceland hotspot may be much older than the earliest rifting of what is now the northernmost Northeast Atlantic.
