Summary
The Elysium quadrangle includes part of the vast, relatively low and featureless plains that encircle the subpolar region of Mars immediately north of the more elevated and cratered equatorial belt. The plains are interrupted in the northwest by two large volcanoes, second only in size and youthful appearance to some of the large constructs that form the planet’s most prominent volcanic center in the Tharsis region several thousand kilometres to the east (Carr, 1975). The large irregularity shaped crater Orcus Patera, at the east boundary of the map, closely resembles the lunar crater Schiller but is more than twice as long. A band of knobby, relatively old terrain extends in a broad arc northeastward through the center of the quadrangle. [...]
Summary
The Elysium quadrangle includes part of the vast, relatively low and featureless plains that encircle the subpolar region of Mars immediately north of the more elevated and cratered equatorial belt. The plains are interrupted in the northwest by two large volcanoes, second only in size and youthful appearance to some of the large constructs that form the planet’s most prominent volcanic center in the Tharsis region several thousand kilometres to the east (Carr, 1975). The large irregularity shaped crater Orcus Patera, at the east boundary of the map, closely resembles the lunar crater Schiller but is more than twice as long. A band of knobby, relatively old terrain extends in a broad arc northeastward through the center of the quadrangle. Thus, plains, volcanoes, and knobby terrain constitute the major physiographic and geologic subdivisions within the map area. In places, the plains and the knobby terrain are similar in appearance to the mare and terra regions of the Moon although they lack comparable contrasts in albedo.
Digitized 1:5,000,000-scale geologic map of the Elysium Quadrangle of Mars. Oringinally mapped on Mariner 9 imagery. The map was imported into ArcMap and georeferenced to the Mars THEMIS basemap. Contacts and geologic units were digitized and attributed based on type and unit name.
