Presentation Transcript

  1. Young Tectonic Events in Martian Chaotic Terrain • A faulted landslide is an example of recent subsidence and tectonic activity in Aureum Chaos, Mars • The feature is estimated to be less than 2 million years old--very modern in Martian geologic time • It is so modern that researchers suggest the tectonic activity may still be active Landslide

  2. Young Tectonic Events in Martian Chaotic Terrain Geomorphic map based on HiRISE image data • Landslide is cut by fractures that line up with East-facing scarp • Tectonic activity postdates a ~2 my old dune field (age estimated by crater counting)

  3. Young Tectonic Events in Martian Chaotic Terrain • If fault activity is recent, then fractures or fissures may be important sites for future geo- physical exploration or seismic networks • Could be important places to study the circulation or release of fluids/gases from the crust • Has interesting astrobiological ramifications on the distribution and/or cycle of water in the Martian crust and the potential development of micro- environments to harbor or sustain life
