THEMIS: Tectonics meets volcanism in Claritas Fossae

THEMIS Image of the Day, January 10, 2019. This VIS image shows part of Claritas Fossae. The linear features (fossae) are faults. This region of Mars had very active tectonism and volcanism, resulting in the huge volcanos like Arsia Mons … Continue reading
