Abstract The formation of tectonic structures on icy satellites may have resulted from one or more of several geologic processes: global volume change due to internal temperature change, H2 O-ice phase changes, or ice-silicate differentiation; mantle convection driven by thermal or compositional heterogeneities; tidal deformation; and impact-related processes including formation of fracture systems, seismic disruption of areas antipodal to impact sites, basin collapse, and global reorientation. Observed tectonic structures and their associated volcanic deposits are classified herein into six basic assemblages on the basis of their morphology and spatial arrangement: (1) pervasive troughs and scarps occurring at globally coherent orientations; (2) throughgoing troughs and bands of troughs, generally associated with volcanic materials; (3) linear to curvilinear ridges; (4) volcanically modified systems of concentric and radial scarps and furrows; (5) regional volcanic and tectonic centers; and (6) grooved terrain intimately associated with light-colored volcanic deposits. Comparison of these assemblages with predicted manifestations of different geoiogic processes may lead to some understanding of the relationship of volcanic and tectonic features to the endogenic and exogenic processes that have affected icy satellites.
