Tharsis volcanic dome tagged posts

Scenario for a TPW driven by a late growth of Tharsis contemporaneous with valley network incision.

The surface of the planet Mars tilted by 20 – 25 degrees 3 to 3.5 billion years ago. This was caused by a massive volcanic structure, the Tharsis volcanic dome, which is the largest in the Solar System. Because of its extraordinary mass, it caused the outer layers of Mars (its crust and mantle) to rotate around its core. The discovery of this huge shift changes our vision of Mars during the first billion years of its history, at a time when life may have emerged...
