Terrain Types and LocalScale Stratigraphy of Grooved Terrain on Ganymede

Grooved terrain is subdivided on the basis of pervasive morphology into (!) groove lanes elongate parallel groove bands, (2) grooved polygons polygonal domains ofparallel grooves, (3) reticulate rrain polygonal domains of orthogonal grooves, and (4) complex grooved terrain polygons with several complexly cross-cutting groove sets. Detailed geologic mapping ofselect areas, employing previously e...

Grooved Terrain on Ganymede: First Results from Galileo High-Resolution Imaging

allowing extrapolation of the observed brightness and topographic relationships to the rest of the imaged area. Distinct High-resolution Galileo imaging has provided important geological units are apparent across the region, and ridges and insight into the origin and evolution of grooved terrain on grooves are ubiquitous within these units. The stratigraphically Ganymede. The Uruk Sulcus target...

Physical 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...
