Fienga - Lunexit Team)199 visiteCaption NASA:"Wider context for this Dunefield is shown here in a mosaic of two images from the Thermal Emission Imaging System on NASA's Mars Odyssey Orbiter, encompassing the dark-toned Sand Dunefield on the floor of an Unnamed Impact Crater located near 49,8° South Latitude and 325,4° West Longitude.
In this image, North is approximately up and Sunlight illuminates the scene from the upper left". MareKromium

Dunes-PaleoDunes-1.jpgPaleodunes (1 - Original NASA/MGS/MSSS b/w Frame)53 visiteCaption NASA:"A pair of MGS-MOC images shows close-up views of a Sand Dunefield that was first detected by the Viking Orbiters in the late 1970's. What is surprising about the MOC images is that they reveal a dune field unlike any other thus far seen on Mars: this one has Impact Craters on its Surface, and LOTS of them! The field of parallel Ridges North of the Dunefield is a wind-eroded material named "Apollinaris Sulci". It is possible that the Dunefield shown here was once covered by this wind-eroded material and was later exhumed. Regardless, the Dunes were somehow hardened and have been exposed as hard rock on the Martian Surface long enough for many Impact Craters smaller than a few hundred meters (such as few hundred yards) across to form. These Dunes are therefore quite ancient: one might say that this is a 'fossilized' Dunefield".

Dunes-PaleoDunes-2.JPGPaleodunes (2 - Original NASA/MGS/MSSS b/w Frame)53 visiteCaption NASA:"A similar effect at a much smaller scale can be seen by examining some Sandstones and Siltstones on Earth (if conditions were right, ripples formed in either water or wind are preserved in such rocks). The first MOC view, labeled M03-00006, was taken on July 1, 1999. The second view, M07-05007, was acquired September 26, 1999. Both MOC images are illuminated from the left. The Dunefield is located East of the Apollinaris Patera volcano and North-East of Gusev Crater (at about 12,5° South Lat. and 181° West Long.)".
