Melas Chasma is a canyon on Mars, the widest segment of the Valles Marineris canyon system, located east of Ius Chasma at 9.8°S, 283.6°E in Coprates quadrangle. It cuts through layered deposits that a

Melas Chasma in mosaic of THEMIS infrared images, with parts of Ius, Candor and Coprates chasmata visible at the upper left, top and lower right, respectively. Enormous landslide deposits are visible near the junctions of Melas Chasma with each of the neighboring chasmata. Numerous graben ("fossae") and ridges ("dorsa") stretch across the plateau outside the canyons' rims.
