THEMIS: Cracks, pits, faults, & graben in the Labyrinth of Night
THEMIS Image of the Day, October 25, 2016. This VIS image shows some of the graben which form Noctis Labyrinthus. Graben are formed when pairs of faults cause the material between them to move downward, creating the linear trough. The … Continue reading
