RE: Geology of Iceland - Part 5: Magmas and Rocks
I like the first diagram a lot, shows how the island slowly but steadily changed over time. If I am reading it correctly, it shows that the oldest magma is on the edges of the island, which would make sense. Is that correct?
Yes, it is. Because of the structure of the mid ocean ridge, material is slowly pushed outwards, resulting in the observable age progression from the center to the edge of the island.
