Iceland is located on the Mid-Atlantic Ridge. On the top of this ridge there is a rift, in between the Eurasian tectonic plate and the North-American tectonic plate. These two plates drift away from each other. In 1930 Sir Arthur Holmes made it clear that mantle currents make these movements possible. Step by step the mechanism of tectonic drift has been revealed, and my analysis represented here of the convection current system is a contribution to further clarifying the details of the inner structure of Earth.

I am a geologist, graduated from the University of Iceland, and taught geology for a few years. I have gained some knowledge about Earth's inner structure, so I provide this website as my contribution to answer one of the greatest questions remaining within the realm of geoscience. Experiments show that the mantle should form convection rolls when close to the melting point. I took this literally, and calculated the dimensions and shape of these mantle convection rolls. Then I compare that model with the surface. This makes it possible to provide many interesting examples about geology found on my blog. View all posts by Steingrimur Thorbjarnarson
