Summary
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.

Digitized 1:500,000-scale geologic Map of the Western Ophir Planum Region, Mars. Originally mapped on Viking imagery. The scanned map sheet was imported into ArcMap and georeferenced to the more current 2014 global THEMIS Daytime IR mosaic basemap. Contacts and geologic units were digitized and attributed based on type and unit name.
