Morphology and emplacement of a long channeled lava flow near Ascraeus Mons Volcano , Mars

[1] Channeled lava flows, hundreds of kilometers long, are common on the lower flanks of the Tharsis Montes on Mars. Our analysis of a 690-km-long lava flow along the southwest perimeter of Ascraeus Mons shows that it was emplaced on low local slopes (<0.3 ), with a deep channel ( 20 m), and at high effusion rates (19,000–29,000 m/s) calculated from the… CONTINUE READING
