Geologic map of the Mare Australe area of Mars

The south polar region of Mars is among the most geologically diverse on the planet. The areas is within the heavily cratered hemisphere of Mars but is distinguished by a variety of younger, regionally extensive deposits and an assemblage of unique erosional forms. The spectrum of units varies from the oldest to the youngest on the planet. The oldest unit, typifying the cratered hemisphere, is the

Geologic map of the Mare Tyrrhenum Quadrangle of Mars

The Mare Tyrrhenum quadrangle is bound by lat 0˚ and 30˚ S and long 225˚ W. and 270˚ W. The central part of the quadrangle is dominated by Tyrrhena Patera, a large shield volcano, and associated low-albedo ridged plains that probably are basaltic lava flows similar to the lunar maria. The western, northern, and eastern margins of the quadrangle are located in cratered terrains of higher elevation.
