In Iceland divergent boundaries between plates can be watched directly. Plates also meet in Siberia, but in much more obscure way. Map showing the exact location is hard to find. There should be similar logic everywhere for boundaries between tectonic plates, so let us check Siberia:
The so called MORVEL model shows most plates location, so please compare it to what is shown here. The exact comparison can then be made in a similar way as for Iceland where every detail of how the plates are deviding from each other can be traced accurately with the mantle convection cell model.
