[1] We have developed a thermal model of Titan's interior to study changes in volume during partial freezing or melting of a subsurface ocean due to heat flux variations from the interior. We find that the long-term cooling of Titan can cause global volume contraction ΔV/V ∼0.01. We then simulate two-dimensional contractional deformation of Titan's icy lithosphere, finding that contractional deformation can produce tectonic activity and fold formation. Folds could potentially achieve a… Expand

Structural and tidal models of Titan and inferences on cryovolcanism
Titan, Saturn's largest satellite, is subject to solid body tides exerted by Saturn on the timescale of its orbital period. The tide-induced internal redistribution of mass results in tidal stressExpand
Do Titan's mountains betray the late acquisition of its current atmosphere?
Titan may have acquired its massive atmosphere relatively recently in solar system history [1,2,3,4]. Prior to that time, Titan would have been nearly airless, with its volatiles frozen orExpand
A Global Geomorphologic Map of Saturn’s Moon Titan
TLDR
The results show that Titan’s surface is dominated by sedimentary or depositional processes with a clear latitudinal variation, with dunes at the equator, plains at mid-latitudes and labyrinth terrains and lakes at the poles. Expand
The tectonics of Titan: Global structural mapping from Cassini RADAR
Abstract The Cassini RADAR mapper has imaged elevated mountain ridge belts on Titan with a linear-to-arcuate morphology indicative of a tectonic origin. Systematic geomorphologic mapping of theExpand
Global contraction/expansion and polar lithospheric thinning on Titan from patterns of tectonism
We investigate the underlying physical processes that govern the formation and evolution of Titan's tectonic features. This is done by mapping mountain chains and hills using Cassini RADAR dataExpand
Morphotectonic features on Titan and their possible origin
Abstract Spectro-imaging and radar measurements by the Cassini–Huygens mission suggest that some of the Saturnian satellites may be geologically active and could support tectonic processes. InExpand
Role of fluids in the tectonic evolution of Titan
Abstract Detailed analyses of slopes and arcuate planform morphologies of Titan’s equatorial mountain ridge belts are consistent with formation by contractional tectonism. However, contractionalExpand
The landscape of Titan as witness to its climate evolution
We investigated the range of Titan climate evolution hypotheses regulated by the role, sources, and availability of methane. We analyzed all available image data (principally synthetic aperture radarExpand
Global Patterns of Tectonism on Titan from Mountain Chains and Virgae
This research is based on the exploration of tectonic patterns on Titan from a global perspective. Several moons in the outer solar system display patterns of surface tectonic features that implyExpand
Forming Europa’s folds: Strain requirements for the production of large-amplitude deformation
Abstract The surface of Jupiter’s iconic icy satellite Europa is dominated by tectonic features that have formed in extension. In contrast, features that have formed in contraction appear to be rare.Expand
