Geologic map of Pavonis Mons Volcano, Mars Geologic map of Pavonis Mons Volcano, Mars
The geologic map shows lava flows and fan-shaped deposits on Pavonis Mons, the central of three large shield volcanoes (Arsia, Pavonis, and Ascraeus Montes) that form the Tharsis Montes volcanic chain. The volcanoes lie along the crest of a regional northeast-trending rise that extends more than 3,000 km across the western equatorial region of Mars (fig. 1). The volcanic history of...
Geologic map of the MTM -85280 quadrangle, Planum Australe region of Mars Geologic map of the MTM -85280 quadrangle, Planum Australe region of Mars
The polar deposits on Mars are of great interest because they probably record martian climate variations (Thomas and others, 1992). The area shown on this map includes polar layered deposits with distinct low-albedo features and a sharp boundary between the layered deposits and the moderately cratered unit that forms the floor of Chasma Australe. Detailed mapping of this quadrangle was...
