I don't know if this is the best place to open the topic, but I prefer open here than South America regional board, because more people can show another examples and similarities about rock formations or mountains in the world.
I have a good example about this research, showing two places of different continents: South America and Africa. In despite of these two continents were united ( all continents ), the coincidence is incredible.
take a look:
Pai Inacio Mountain - Chapada Diamantina - Brazil
Tafelberg and The Spout - Drakensberg Range - South Africa
