Geologic map of the western Ophir Planum region (MTM -10067) of Mars

January 1, 1998

The map area, in the Coprates 1:2,000,000-scale quadrangle MC-18 NW lies in the heart of the Valles Marineris trough system.  The western part of Ophir Planum (36,660 km2) occupies 40 percent of the map areas; parts of Candor, Melas, and Coprates Chasmata make up the remainder. The troughs contain distinctive landslide deposits, normal faults, possible young volcanic rocks, and layered materials. Ophir Planum plateau is deformed by normal faults and grabens in an en echelon array that is unique along the Valles Marineris.
