Considering the jumps of rift zones over Iceland, and seeing the pace of those ‘jumps’, there seems to be a possibility that another rift zone opened before the ‘first one’.
Was there another Rift Axis?
The activity would then have occurred about 25 million years ago, probably at the same time as when the Northwest Rift Axis was active. The prospective rift axis is pointed out with a question mark.
I have a BS degree in geology, BA in anthropology, graduated in Chinese language and as a certified tourist guide. I provide this website about my contribution to answer the greatest question remaining about our Earth. I have analyzed the convection rolls within the Earth's mantle and how they affect the surface. This makes it possible to provide many interesting examples about geology found on my blog.
