PSP_005442_1660_RED_abrowse-PCF-LXTT.jpgGraben in Memnonia Fossae (Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team)135 visiteThis HiRISE image shows a Graben (roughly 2,5 Km or 1,6 miles wide) cutting a Ridge near Memnonia Sulci, a Region of Mars West of the massive Tharsis Volcanic Province. A Graben is a Trough created when 2 normal Faults (Faults dipping at an angle, with the overhanging wall sliding downwards) opposite each other lower the block of rock in between them. They are commonly associated with the tectonically-driven extension of a region and are also found in volcanic areas. Graben occur on many planets and moons, including Earth.
In this case, the Graben (running roughly East-West, indicating extension in the North-South direction) is cutting a Ridge, showing that it is more recent. The Ridge may also be tectonic in origin, therefore representing a different epoch and different type of tectonic activity.
Relationships like this can be used to determine the sequence of events in the history of the Region. The Graben Walls can also expose the local rocks at depth; in this case there is no obvious indication of Layering.MareKromium

ESP_022612_1855_RED_abrowse-PCF-LXTT.jpgFeatures of Elysium Planitia (Absolute Natural Colors; credits for the additional process. and color: Dr Paolo C. Fienga - Lunexit Team)134 visiteQuattro interessanti (ma per nulla "misteriose, come invece "suggerisce" la NASA...) Surface Features individuate sulla Pianura di Elysium dalla Sonda MRO.
Da Sx a Dx:
1) modesto Windstreak con evidente bruciatura del suolo dovuta, molto probabilmente, ad un recente "impatto esplosivo" (si tratta di un bolide che in parte arriva ad impattare il suolo ed in parte si consuma, disintegrandosi - in maniera esplosiva, appunto -, nelle immediate prossimità del suolo);
2) probabile fase iniziale nella formazione di un pozzo da collasso;
3) altro modesto Windstreak con evidente bruciatura del suolo (idem come al punto 1 che precede); la curiosità è che questo secondo (e pure recente) "impatto esplosivo" si è verificato circa ad ore 6, in prossimità del margine (Rim) di un pre-esistente cratere ormai sepolto (Buried Crater) oppure - più probabilmente - all'interno di un'area che pure sta iniziando a collassare e che, nei secoli (o millenni), creerà un Collapse Pit - di cui la Pianura di Elysium è piena);
4) modestissimo, in termini di profondità, "pozzo veriticale da collasso", o Skylight.MareKromium
