New Elements on Stratigraphy of South Polar Layered Deposits on Promethei Lingula Region and a Possible Structural Approach
Introduction: South Polar Layered Deposits (SPLD) have been analyzed by several authors [1,2,3, 4] in order to describe mayor layers sequences using visible images [1,2,3,4] and sounding radar datasets (Mars Express MARSIS and MRO ShaRAD [1,2]), defining different units. [1] mapped three main SPLD units through several distinctive erosion-resistant marker beds or packets of layers. In particula...
متن کاملDensity of Mars' south polar layered deposits.
Both poles of Mars are hidden beneath caps of layered ice. We calculated the density of the south polar layered deposits by combining the gravity field obtained from initial results of radio tracking of the Mars Reconnaissance Orbiter with existing surface topography from the Mars Orbiter Laser Altimeter on the Mars Global Surveyor spacecraft and basal topography from the Mars Advanced Radar fo...
متن کاملIntegrating radar stratigraphy with high resolution visible stratigraphy of the north polar layered deposits, Mars
Shallow Radar (SHARAD) on board NASA’s Mars Reconnaissance Orbiter has successfully detected tens of reflectors in the subsurface of the north polar layered deposits (NPLD) of Mars. Radar reflections are hypothesized to originate from the same material interfaces that result in visible layering. As a first step towards verifying this assumption, this study uses signal analyses and geometric com...
متن کاملSouth Polar Layered Deposits of Mars: The cratering record
[1] Data from the Mars Orbiter Laser Altimeter (MOLA) and Mars Orbiter Camera (MOC) instruments aboard the Mars Global Surveyor (MGS) were used in a detailed search of a selected part of the South Polar Layered Deposits (SPLD) for impact craters. Impact craters with diameters from 0.8 to 5 km were identified from a MOLA-derived shaded relief map and were primarily validated using individual MOL...
