THEMIS: Small graben in Acidalia Planitia
THEMIS Image of the Day, June 17, 2019. This false-color image shows a graben located in Acidalia Planitia. Graben are depressions caused by movement of material downward between paired tectonic faults. The THEMIS VIS camera contains 5 filters. The data … Continue reading

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

THEMIS: Tectonic scars in Sirenum Fossae
THEMIS Image of the Day, January 4, 2019. The linear features in this VIS image are graben called Sirenum Fossae. Graben are formed when blocks of material move downward between parallel faults. The faults were created by tectonic stresses in … Continue reading

THEMIS: Tectonic chaos in Claritas Fossae
THEMIS Image of the Day, December 27, 2018. Located between the lava plains of Daedalia Planum and Solis Planum, Claritas Fossae is a graben-filled highland. Graben are formed by tectonic activity. In this region of Mars extensive and long lived … Continue reading

THEMIS: Faulting and collapse in Sirenum Fossae
THEMIS Image of the Day, December 19, 2018. The linear depressions in this VIS image are part of Sirenum Fossae. These depressions are called graben, which form by the down drop of material between two parallel faults. The faults are … Continue reading

THEMIS: Graben cuts across Claritas Fossae crater
THEMIS Image of the Day, December 7, 2018. Located on the northern margin of Aonia Terra, this unnamed crater interacts with one of the fossa, also called a graben. In this image, it is apparent that the tectonic depression crosses … Continue reading

THEMIS: Solis Planum lava flows and graben
THEMIS Image of the Day, November 30, 2018. Today’s VIS image shows part of Solis Planum. Both volcanic and tectonic forces created the features in this image. The linear features that run diagonally across the image are fault features called … Continue reading
