THEMIS: Tectonics showcase in Sirenum Fossae
THEMIS Image of the Day, November 29, 2016. Today’s VIS image shows part of Sirenum Fossae, a large graben on the margin between Terra Sirenum and Daedalis Planum. Grabens are formed by the downward movement of material between parallel tectonic … Continue reading

HRSC: A record of ancient tectonic stress
Sets of ridges and troughs some 1000 km north of the giant Olympus Mons volcano contain a record of the intense tectonic stresses and strains experienced in the Acheron Fossae region on Mars 3.7–3.9 billion years ago. This scene, captured … Continue reading

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

THEMIS: Faults and cracks in Claritas Fossae
THEMIS Image of the Day, October 5, 2016. The linear depressions in this VIS image are some of the numerous graben that make up Claritas Fossae. Graben form when two faults cause a block of material to be dropped to … Continue reading

HiRISE: Faulting Mars
This region of Xanthe Terra has mostly been contracted due to thrust faulting, but this local region shows evidence of extensional faulting, also called normal faulting. When two normal faults face each other, they create a bathtub-like depression called a … Continue reading

THEMIS: Graben in Nili Fossae
THEMIS Image of the Day, July 20, 2016. Nili Fossae is a large band of parallel graben located to the northeast of Syrtis Major. The graben in this VIS image were formed by tectonic activity, with faulting that creates the … Continue reading
