Eridania is a large region in the southern hemisphere of Mars that is believed to be covered by ancient crust and has been subject to volcanic activity.
The study was carried out using data from the Mars Global Surveyor, Mars Odyssey and MRO probes. Scientists have discovered a number of new volcanoes and other traces of volcanic activity, as well as areas with a thin crust that indicates the circulation of rocks between the subsoil and the Martian surface. These processes make Mars similar to the early Earth, where plate tectonics was not yet effective. Researchers have discovered 63 previously unknown volcanoes in the Eridania region.
These discoveries suggest that Mars experienced a rock cycle process similar to Earth in ancient times; This may indicate similar geochemical evolution of both planets.
