Considering that the coast of Baffinsland is created by rifting of the American continent, we should also check the same latitudes of Iceland and Baffinsland, just like Iceland and Greenland, and Iceland and Norway. The same result appears:

The mirror image of the West Fjords fits to the coast of Baffinsland! Should we keep on testing this?

If regular convection rolls govern the development of tectonics of the Earth’s crust, we should see comparable formations at regular intervals on the surface. With a model of the convection cell system, this can of course be tested. Let us compare Iceland and Greenland:

The coasts at 66°N are exactly 30° apart, and the tectonics are mirrored so that the West Fjords of Iceland are aligned W34°S, but the fjords of Greenland are aligned W34°N. The main coast line is also mirrored, the West Fjords of Iceland follow the upper most convection cells to the NW (N31.4°E), but the outer coast of Greenland has the direction N31.4°W.

I have formerly compared the West Fjords with the west coast of Norway. The result is always a manyfold match. The interplay of different convection cell layers is apparent. Have in mind that only one basic formula is used for calculating the lines drawn along the coasts and fjords. It is the equation of the convection cell system that explains these repeated tectonic features, which remain hidden until revealed in this way.

A view over the main rift of Thingvellir, extending to the lake Thingvallavatn.

The location of Thingvellir is quite special and makes us combine geology and history in a very special way. But why are the walls of the rift so prominent in the area of Almannagjá and its surroundings? It can be seen on geology maps, and by analyzing the convection cells underneath. Whereas the lake is at the western edge of the Western Volcanic Zone of Iceland (with direction α), the volcanic system of Hengill (with the direction (3/4)α, a large scale rift valley (with the direction (1/2)α, and the NS axis of the relevant polygon of mantle convection cell division lines.

Thingvellir can therefore be explained by referring to the basic formula of convection cells and the derived main tectonic alignments:

Can you find Thingvellir there? And the relevant tectonic alignments?

Please check a detailed geologic map of Iceland and trace the relevant tectonic settings. Then you see why Almannagjá and Hrafnagjá are located where they are 🙂

Hekla is the most outstanding volcano of Iceland. It is not the biggest, not the most dangerous, but the most famous one. According to the analysis presented here, it is located above an upwelling line of mantle convection rolls. The mountain is relatively young, as geologists find it to be mostly made of 3000 years old rock or younger. It last erupted in the year 2000. It looks like a boat with the keel turned upwards, and has to be classified as a mixture of a ridge forming on a fissure swarm and a proper stratovolcano. It is located at a spot where four different convection cell layer division lines cross exactly under the mountain’s top crater. Therefore it is often mentioned in scientific articles that it looks like the volcano has different sources of magma. The mountain can be regarded as the central point of volcanic activity in Iceland, manifested by the fact that the distance to the volcanoes farthest in the east and west, Snæfellsjökull and Snæfell, is exactly the same!
