PSP_007925_1990_RED_abrowse-00.jpgChannels in Jezero Crater Delta (context frame - MULTISPECTRUM; credits: Lunexit)77 visiteBillions of years ago, this water-carved channel in Nili Fossae Region transported sediments across the Martian Surface and deposited them on the floor of an impact crater just south of this image.
The sediments were deposited in a delta-like mound on the floor of Jezero Crater, suggesting that the crater may have contained a lake at the time.MareKromium

PSP_007925_1990_RED_abrowse-01.jpgChannels in Jezero Crater Delta (extra-detail mgnf - MULTISPECTRUM; credits: Lunexit)63 visiteThis extra-detail mgnf shows a section of one channel in greater detail. Wind-blown dunes or ripples now cover much of the channel floor, but in some places the older channel floor is visible. Here, the channel bed has a layered appearance. The plains outside the channel are fractured into polygonal patterns.
The CRISM instrument has detected water-bearing clay minerals in these plains, which were eroded by flows down the channel.
Clays are also seen in the sediments deposited on the floor of Jezero Crater.MareKromium
