Global Reor!entation and Its Effect on Tectonic Patterns on Ganymede

چکیده
The perturbation to the momental figure of Ganymede by the impact basin Gilgamesh was modelled, and it was found that the format, ion of the basin could have significantly reoriented the satellite. Global trends of groove orientation suggest that groove sets formed in reactivated zones of weakness, which were created by tidal despinning and furrow formation. The paleo•ole n which despinning occurred was hifted about 15 after the emplacement of most grooved terrain. The youngest grooves have orientations consistent with those expected for fractures caused by

Introduction to the special section: Galileo Mission results from the icy Galilean satellites
The four largest satellites of Jupiter, Io, Europa, Ganymede, and Callisto, have fascinated scientists since their discovery by Galileo in 1610. The four bodies, named the Galilean satellites in honor of their discoverer, represent what might be viewed as a miniature solar system, with planet-sized dimension, systematically changing densities, and as diverse a set of surface characteristics, ag...
متن کاملTectonic and Volcanic Evolution of Dark Terrain and Its Implications for the Internal Structure and Evolution of Ganymede
Furrows in ancient dark terrain on Ganymede form three systems that are each hemispheric or greater in scale. The oldest of the systems, designated system ]II, is dominated by approximately concentric troughs centered on about 60øN,50øW. System I, in the anti-Jovian hemisphere, contains concentric and subradial furrows arrayed around a large, degraded palimpsest centered at 15øS,165øW. Furrows ...
متن کاملEvidence for Europa-like tectonic resurfacing styles on Ganymede
[1] Very high-resolution imaging and stereo topographic data obtained during the Galileo G28 encounter with Ganymede show 1) evidence for Europa-like, crustal spreading and resurfacing to form portions of the bright terrain, and 2) bright terrain that appears smooth at Voyager resolution (and thus a strong candidate for cryovolcanism) but instead is tectonically deformed and lacks embayment rel...
متن کاملGlobal geological mapping of Ganymede
We have compiled a global geological map of Ganymede that represents the most recent understanding of the satellite based on Galileo mission results. This contribution builds on important previous accomplishments in the study of Ganymede utilizing Voyager data and incorporates the many new discoveries that were brought about by examination of Galileo data. We discuss the material properties of ...
متن کاملPhysical Models of Tectonic Resurfacing on Ganymede
Introduction: Grooved terrain on Ganymede generally occurs as individual lanes and polygonal crosscutting swaths of bright terrain. Internally, grooved terrain swaths consist of parallel to sub-parallel ridges and troughs at a variety of scales (Fig. 1); the ridges and troughs show generally similar morphology, size, and orientation. Grooved terrain on Ganymede has been interpreted by most auth...
