Division between convection rolls from Iceland to Greenland can be compared with the map below.Please compare this with the main line from Iceland to Greenland of the Convection Rolls Model.
In the mantle there is a layer that explains the heat anomaly found under the glacier of Greenland. It has been calculated and is shown here above.
The lines are obviously approximately the same. Usually geologists regard Vatnajökull as the site of hot spot, so therefore someone has drawn the line over Iceland a little bit eastwards of the calculated division line between convection rolls.
I have a BS degree in geology and provide this website about my analysis of convection rolls in the Earth's mantle and how they affect the surface.
