China, like other areas, has been gradually shaped by the tectonic drift of the continents. But at every moment in Earth’s history it is possible to compare the surface with the magma currents underneath. China has been formed in a particular way, and referring to the convection cell pattern it can be clarified further.
The perfectly circular shape of the SE coast of China is centered at the main division line of convection cells, exactly at 32°N where the mantle rolls are oriented NS.

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.
