Convective modelling of gravity, topography and melt generation at the Tharsis Rise, Mars
The observed long-wavelength gravity and topography at the Tharsis Rise, and the inferred heat flux and melt generation rate, are modelled using a convection code. The code is axisymmetric and isoviscous and incorporates a conductive lid and the effects of lithospheric rigidity on the observables. Models which fit the observations have high mantle viscosities (5-28×10 Pa s) and 80% or less inte...
متن کاملLate Noachian “icy Highlands” Mars: Implications for Melting and Ground- Water Recharge across the Tharsis Rise
Introduction: Results from modeling of an early CO2 martian atmosphere and late Noachian climate predict that at pressures greater than a fraction of a bar, atmosphere-surface thermal coupling occurs, resulting in adiabatic cooling of high areas across Mars [1]. This effect promotes the transport of water from warmer low-lying areas to the highlands where deposition and accumulation of water ic...
متن کاملConstraints on the Evolution of the Tharsis Region of Mars
Introduction: The western hemisphere of Mars is dominated by topography associated with the Tharsis volcanic province. A range of models for the formation and/or evolution of this region have been proposed and include (1) dynamic support of topography by a large mantle plume [1,2], (2) regional uplift due to underplating of crustal material derived from the northern hemisphere [3], (3) uplift d...

متن کاملThe Magmatism of Mars Inferred from Chemical Composition of Shergottites
Introduction: It is well known that shergottites have a large variation of rare earth elements (REEs) abundance patterns and isotopic compositions. Jones [1] and Borg and Draper [2] suggest that light REEs (LREEs)-enriched shergottites resulted from mixing of a LREEs-enriched component with their parental magma. The LREEsenriched component is thought to be either Martian crust [1] or a KREEP-li...
