Geologic map of Arsia Mons Volcano, Mars

The geologic map shows the flanks and summit caldera of Arsia Mons, the southernmost of three large shield volcanoes (Arsia, Pavonis, and Ascraeus Montes) that form the Tharsis Montes volcanic chain (fig. 1). The volcanoes lie along the crest of a regional northeast-trending rise that extends more than 3,000 km along or near the planet-wide boundary that separates the southern highlands from the n

Geologic map of the Sherbrooke-Lewiston area, Maine, New Hampshire, and Vermont, United States, and Quebec, Canada

This map is part of a folio of maps of the Lewiston 1° x 2° quadrangle, Maine, New Hampshire, and Vermont, and part of the Sherbrooke 1° x 2° quadrangle, Maine, New Hampshire, and Vermont, United States, and Quebec, Canada, prepared under the Conterminous United States Mineral Assessment Program (CUSMAP). Adjacent areas in Quebec are shown, in order to illustrate the geologic continuity between no

Geologic/geomorphologic map of the Chryse Planitia region of Mars

Since the 1970’s, when the Mariner 9 spacecraft revealed the geologic diversity of Mars, the Chryse Planitia region has been noted for its immense outflow channels and chaotic terrain (McCauley and others, 1972; Sharp and Malin, 1975; Baker, 1982, chap. 3; Mars Channel Working Group, 1983). Various proposals for the origin of these features have been offered; most workers have favored a mechanism

Map of Mars showing channels and possible paleolake basins

The significance of water in the geologic evolution of Mars was strikingly revealed by Mariner and Viking spacecraft images.  Theoretical and conceptual models of the Martian climate through time range from a brief, early, warm, and wet period followed by protracted desertification to episodic oceans that inundated the northern lowland plains and produced temperate climatic regimes.
