Abstract

Using stereo generated topography of Dione, a moon of Saturn, we infer flexure across a prominent ridge on the leading hemisphere to estimate local elastic thickness and place constraints on Dione s thermal evolution. Assuming topography is related to the flexing of a broken elastic plate, we estimate an effective elastic thickness of 3.5±1km. This local estimate is in good agreement with global values derived from long wavelength topography. Corresponding heat fluxes of 25–60mW/m2 are much greater than those expected for a ...
