Strike-slip motion and double ridge formation on Europa
[1] There is abundant observational evidence for strike-slip displacement on the surface of Europa. Strike-slip motion between crustal blocks produces shear heating and an increase in temperature. We model the shear heating within the ice crust using a two-dimensional, finite difference formulation, with a near-surface brittle layer of constant specified thickness and a Newtonian ductile layer ...
متن کاملStrike-slip fault patterns on Europa: Obliquity or polar wander?
Variations in diurnal tidal stress due to Europa’s eccentric orbit have been considered as the driver of strike-slip motion along pre-existing faults, but obliquity and physical libration have not been taken into account. The first objective of this work is to examine the effects of obliquity on the predicted global pattern of fault slip directions based on a tidal-tectonic formation model. Our...
متن کاملEruptive Volcanism on Saturn’s Icy Moon Dione
Introduction: Although Enceladus has garnered the greatest attention, Saturn’s other icy moons also betray a diverse range of phenomenon (e.g., Rhea‘s ring, Iapetus‘ ridge, Tethys’ fracture). Even in Voyager’s limited global mapping, some cryptic evidence of resurfacing was evident [e.g., 1, 2]. Global mapping by Cassini reveals that a large resurfaced terrain covers much of the leading hemisph...
متن کاملTides on Europa, and the thickness of Europa’s icy shell
[1] It has been shown previously that measurements of tides on Jupiter’s moon Europa can be used to determine whether there is a liquid ocean beneath this moon’s icy outer shell. In this paper we examine the further possibility of constraining the thickness of the icy shell in the case where a liquid ocean exists, by combining measurements of tidal gravity obtained from tracking an orbiting spa...
متن کاملNumerical Modelling of Impact Cratering on the Moon and Icy
There is growing evidence of a brine ocean beneath the ice crust of Europa. The possibility of this ocean hosting the development of simple life depends on the interaction of the ocean with the satellite’s surface where oxidants and organic compounds are believed to be formed by the breakdown of H2O and CO2 ices [1]. Transfer of these organics is considered possible if the ice crust is thin, ma...
