ESP_020929_1360_RED_abrowse.jpgUplifted Bedrock (Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team)333 visiteCaption NASA:"Large Impact Craters expose deep Bedrock. After the transient cavity forms, the Crater Floor rebounds and creates a permanent structural Uplift, typically equivalent to about 10% of the Crater diameter.
A Crater approx. 70 Km (43,47 miles) wide like this one, can raise up and expose Bedrock that was approx. 7 Km (4,34 miles) lower in elevation prior to the Impact.
Deeper rocks are usually older, and on Mars the oldest rocks are interesting because they are more likely to have been altered by water and provide clues to ancient environments and processes. This image reveals good Bedrock exposures with diverse rock types (as indicated by colors and textures)".MareKromium

Coord. (centered): 66,6° North Lat. and 247,8° East Long.
Spacecraft altitude: 315,6 Km (such as about 197,2 miles)
Original image scale range: 31,6 cm/pixel (with 1 x 1 binning) so objects ~ 63,1 cm across are resolved (with 2 x 2 binning)
Map projected scale: 25 cm/pixel
Map projection: POLAR STEREOGRAPHIC
Emission Angle: 7,5°
Sun-Mars-Spacecraft (or "Phase") Angle: 74,0°
Solar Incidence Angle: 69° (meaning that the Sun is about 21° above the Local Horizon)
Solar Longitude: 0,3° (Northern Spring)

ESP_020793_1935_RED_abrowse-PCF-LXTT.jpgElliptical Impact Crater or Crater Chain? (Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team)317 visiteCaption NASA:"This image shows what appears to be a highly Elliptical Crater, which would be unusual. Closer examination reveals that it is probably two overlapping Craters that formed concurrently, plus several smaller Craters aligned with the Long Axis of the elliptical depression.
This type of "Crater Chain" can form from a highly oblique impact, in which the Impactor (Bolide) trajectory is almost parallel to the Surface".MareKromium
