Geologic map of the MTM 90000 area, Planum Australe region of Mars Geologic map of the MTM 90000 area, Planum Australe region of Mars
Published geologic maps of the south polar region of Mars, made using either Mariner 9 (Condit and Soderbloom, 1978) or Viking Orbiter (Tanaka and Scott, 1987) images, identified only layered deposits of polar ice within this map area. Layered deposits probably underlie all of the other units shown in the map. The residual polar ice cap, partial frost cover, and two low-albedo units are...
Geologic map of the Pompeii Quadrangle (MTM 20057), Maja Valles region of Mars Geologic map of the Pompeii Quadrangle (MTM 20057), Maja Valles region of Mars
The Pompeii quadrangle is in the northern Maja Valles between Lunae Planum to the west and Xanthe Terra to the east (fig. 1). Approximately two-thirds of the surface is relatively smooth plains, and the other one-third is subdued, cratered, upland plateau.
