A few years ago, dune-ghosts were discovered on Earth – the rock-filled gaps that formed when an old cluster covered the sedimentary rocks and drowned. Later, the winds blew the sand, and the rocks remained.

Marseille is now discovered. Several hundred ghost dunes have been discovered in the basins of the Labyrinth of Noctis and Hellas. Both regions were flooded about two billion years ago: Noctis Labyrinthus was probably filled with lava and the basin of Hell was made up of water and sedimentary rocks
This discovery shows that at that time, Marsea was blown by strong winds forming superficial structures. very different from today 's. Traces of ancient clayey sandstone that can give much knowledge about the properties and life of the ancient Martian surface can remain on the edges.
The results of the research are published in the Journal of Geophysical Research: Planets.
