Formation of Ganymede’s grooved terrain by convection-driven resurfacing

The heat flux and strain rate inferred for grooved terrain formation on Ganymede can be produced in a convecting ice shell 10–100 km thick with weak near-surface ice. Smooth linear grooves may have formed by convection-driven lithospheric spreading and long-wavelength compressional folds may form atop convective downwellings, and would possibly be detectable with mapping from ESA’s upcoming Jupiter-Icy Moon Explorer Mission.
