Scientists recently discovered a massive volcano on Mars, temporarily designated ‘Noctis volcano’, with the possible remains of a relict glacier at its base.
About Noctis Volcano:
It is a newly-discovered volcano located just south of Mars’ equator, in Eastern Noctis Labyrinthus, west of Valles Marineris, the planet’s vast canyon system.
The volcano sits on the eastern edge of a broad regional topographic rise called Tharsis, home to three other well-known giant volcanoes: Ascraeus Mons, Pavonis Mons, and Arsia Mons.
The central summit area is marked by several elevated mesas forming an arc, reaching a regional high and sloping downhill away from the summit area.
The caldera remnant–the remains of a collapsed volcanic crater once host to a lava lake–can be seen near the centre of the structure.
Lava flows, pyroclastic deposits (made of volcanic particulate materials such as ash, cinders, pumice and tephra), and hydrated mineral deposits occur in several areas within the structure’s perimeter.
It was active for a very long time on the Red Planet, and in its southeastern part lies a thin, recent volcanic deposit beneath which glacier ice is likely still present.
