Icelandic analogs to Martian flood lavas
We report on new field observations from Icelandic lava flows that have the same surface morphology as many Martian flood lava flows. The Martian flood lavas are characterized by a platy-ridgedExpand


The geology of the Viking lander 2 site
Viking Lander 2 landed on a flat plain of fine-grained sediment overlain by dispersed, evenly distributed boulders. The fine-grained material is probably part of a high-latitude mantle comprisingExpand
The geology of the Viking Lander 1 site
Viking 1 landed on volcanic terrain in the plains of Chryse. Stereo pictures reveal an undulating topography. Bedrock is exposed along several ridge crests. Blocks are more numerous than can beExpand
The canyon system on Mars
Individual Martian equatorial troughs are described, and their stratigraphy, geomorphology and structure are discussed. Possible origins and the overall sequence of events are addressed. Wall rock,Expand
Sedimentary rocks of early Mars.
Affinity for impact craters suggests dominance of lacustrine deposition; alternatively, the materials were deposited in a dry, subaerial setting in which atmospheric density, and variations thereof mimic a subaqueous depositional environment. Expand
Grain-Size and Textural Classification of Coarse Sedimentary Particles
ABSTRACT The Udden-Wentworth grain-size scale is widely used as the standard for objective description of sediment, but it inadequately covers gravel, the dominant fraction in many environments suchExpand
Flexure of Europa's lithosphere due to ridge-loading
Abstract Using photoclinometry, topographic profiles across europan ridges have been produced. These profiles allow the identification of bulges in the terrain adjacent to the ridges. The bulges areExpand
Martian tension fractures and the formation of grabens and collapse features at Valles Marineris
Simple models of the Martian crust are summarized that predict extensional deformation style on the basis of depth, material friction and strength, and hydraulic conditions appropriate to the planet.Expand
Mantled and exhumed terrains in Terra Meridiani, Mars
[1] Hematite-bearing deposits in the Terra Meridiani region of Mars constitute the top stratum of a partially eroded layered complex that covers dissected Noachian-aged cratered terrain. The hematiteExpand
The roughness of natural terrain: A planetary and remote sensing perspective
We examine the various methods and parameters in common use for quantifying and reporting surface topographic “roughness.” It is shown that scale-dependent roughness parameters are almost alwaysExpand
The global topography of Mars and implications for surface evolution.
Elevations measured by the Mars Orbiter Laser Altimeter have yielded a high-accuracy global map of the topography of Mars. Dominant features include the low northern hemisphere, the Tharsis province,Expand
