ESP_014413_0930_RED_abrowse-00.jpgRadial Channels carved by CO2 - a.k.a.: The "Spiders" (CTX Frame - Natural Colors; credits: Lunexit)58 visiteMars’ Carbon Dioxide-based Atmosphere partially condenses every Winter to form Polar Caps of Dry Ice (CO2). In the Spring, the evaporation/sublimation of the ice is a dynamic process and carves Channels into the ground as it escapes back into the Atmosphere.
Often these Channels are radial in nature and are colloquially refered to as “Spiders” although the prefered term for these radially-organized channels is “Araneiform” (which means spider-like).MareKromium

ESP_014353_1685_RED_abrowse-01.jpgLight-Toned Deposits in Noctis Labyrinthus (EDM - Natural Colors; credits: Lunexit)58 visiteCRISM observations of this Region of the Noctis Labyrinthus formation have shown indications of Iron-bearing Sulfates and Phyllosilicate (such as "clay" ----> argilla) minerals.
HiRISE observations have revealed exposed layers which are possibly the sources of the signatures seen by CRISM.
In this image, the layering can be seen on the right side of the image.
On the lower left, instead, a large Dunefield which covers other beds can also be seen.MareKromium
