  • The Apollo landing sites 
    Zimbelman, James R.; https://orcid.org/0000-0002-0420-8453 (Planetary Image Center/Lunar and Planetary Institute, 1987)
    Photographic coverage of the regional setting for the six Apollo landing sites.
  • Concentric Crater Fill on Mars: An Aeolian Alternative to Ice-rich Mass Wasting 
    Zimbelman, James R.; Clifford, Stephen Mark, 1952-; Williams, Steven H. (Lunar and Planetary Institute, 1989)
    We use both moderate and high-resolution images of the Utopia Planitia region (approximately 45°N, 270°W) to assess the morphologic characteristics of concentric crater fill, followed by additional evidence that distinctive ...
  • An Evaluation of Probable Bedrock Exposure in the Sinus Meridiani Region of the Martian Highlands 
    Zimbelman, James R.; Craddock, R. A. (Lunar and Planetary Institute, 1991)
    The study region (15°N to 15°S, 330° to 360°W) includes portions of the classical low-albedo regions of Sinus Meridiani and Sinus Sabaeus and the high-albedo region of Arabia and is entirely within the cratered highlands ...
  • The Evolution of Volcanism, Tectonics, and Volatiles on Mars: An Overview of Recent Progress 
    Zimbelman, James R.; Solomon, Sean C.; Sharpton, Virgil L. (Lunar and Planetary Institute, 1991)
    Mars has been the target of a number of ambitious spacecraft missions, including the American Viking orbiters and landers in the late 1970s and, more recently, the Soviet Phobos spacecraft in 1989. Soon after the Viking ...
  • MECA special session at LPSC XVII : Martian geomorphology and its relation to subsurface volatiles 
    Clifford, Stephen Mark, 1952-; Zimbelman, James R.; Rossbacher, Lisa A.; https://orcid.org/0000-0002-0420-8453 (Lunar and Planetary Institute, 1986)
    Martian volatile inventory, planetary climatic and atmospheric evolution, and the interpretation of various remote sensing data were discussed.
  • MEVTV Workshop on Nature and Composition of Surface Units on Mars 
    Zimbelman, James R.; Solomon, Sean C.; Sharpton, Virgil L.; https://orcid.org/0000-0002-0420-8453 (Lunar and Planetary Institute, 1988)
    Topics addressed include: SNC meteorites and their potential for providing information about the geochemical evolution of Mars; remote sensing; photogeological inferences of Martian surface compositions; and interactions ...
  • Scientific results of the NASA-sponsored study project on Mars : evolution of volcanism, tectonics, and volatiles 
    Sharpton, Virgil L.; Zimbelman, James R.; Solomon, Sean C.; https://orcid.org/0000-0002-0420-8453 (Lunar and Planetary Institute, 1990)
    The objectives of the project are to outline the volcanic and tectonic history of Mars; to determine the influence of volatiles on Martian volcanic and tectonic processes; and to attempt to determine the compositional, ...
  • A spacecraft tour of the Solar System 
    Zimbelman, James R.; https://orcid.org/0000-0002-0420-8453 (Lunar and Planetary Institute, 2002)
    A view of the principal distinctive features of each planet and its natural satellites.
  • The Tharsis Montes, Mars: Comparison of Volcanic and Modified Landforms 
    Zimbelman, James R.; Edgett, Kenneth S. (Lunar and Planetary Institute, 1992)
    The three Tharsis Montes shield volcanos, Arsia Mons, Pavonis Mons, and Ascraeus Mons, have broad similarities that have been recognized since the Mariner 9 reconnaissance in 1972. Upon closer examination the volcanos are ...
  • Volcanoes on Mars 
    Zimbelman, James R.; https://orcid.org/0000-0002-0420-8453 (Center for Information and Research Services/Lunar and Planetary Institute, 1987)
    Illustrates various geologic features on Mars, including some of the best examples of Viking Orbiter images that include constructional volcanic landforms.
