Layered Sedimentary Rocks in Candor Chasma
Layered Sedimentary Rocks in Candor Chasma
ESP_072599_1735  Science Theme: Sedimentary/Layering Processes
Candor Chasma in central Valles Marineris is a huge, deep basin that was once filled with sediments carried by water and/or the atmosphere. Erosion has exposed the intricate structures in the layering.

Dark sand trapped in the crevices helps to accentuate the layering. The light bedrock is rich in hydrated sulfates, and represents a vast reservoir of water (trapped in the sulfate minerals) that is stable in the topics of Mars where any water ice has long ago sublimated into the air.
