Geologic map of the Amenthes Quadrangle of Mars

The Amenthes quadrangle includes two main physiographic and geologic subdivisions. In the southern part of the quadrangle, densely cratered plateaus rise about 3 km above sparsely to moderately cratered plains. The low plains that form Elysium Planitia also build the eastern flank of the Isidis basin, which mostly lies with the adjacent Syrtis Major quadrangle to the west: the Elysium region, one

Geologic map of the Arcadia Quadrangle of Mars

The Arcadia quadrangle of Mars contains three distinct geological provinces: (1) the 1000-km-diameter shield field volcano of Alba Patera, which occupies the southwestern quadrant; (2) the complex Tempe province, which comprises a number of younger volcanic and sedimentary blanket deposits over an ancient, highly cratered crust forming a plateau in the southwestern quadrant; and (3) a plains provi

Geologic map of the Cebrenia Quadrangle of Mars

Most of the Cebrenia quadrangle (lat 30˚ to 65˚ N., long 180˚ to 240˚ W.) is in the circumpolar plains of Mars. Craters from an early episode of intense bombardment have been largely obliterated by later volcanism, tectonism, erosion, and sedimentation by wind and water, and by circumpolar glacial and periglacial processes. South of 47˚ N. the plains are dissected by numerous channels, most of whi
