Tharsis swell represents the largest area of volcanism on Mars and sits adjacent to the dichotomy between the northern lowlands and southern highlands. While a number of investigators have proposed that Tharsis volcanism and topographic swell was caused by a stationary mantle plume, both numerical and tank experiments find that a plume will rise beneath a region of thick lithosphere, hence somewhere beneath the southern highlands on Mars. We present models of crustal thickness which show a… Expand
A hybrid origin of the Martian crustal dichotomy: Degree-1 convection antipodal to a giant impact
Abstract The Martian crustal dichotomy is the stark ∼5 km difference in surface elevation and ∼26 km difference in crustal thickness between the northern lowlands and southern highlands thatExpand
Lithospheric structure of Venus from gravity and topography
Abstract There are many fundamental and unanswered questions on the structure and evolution of the venusian lithosphere, which are key issues for understanding Venus in the context of the origin andExpand
Sources of water for the outflow channels on Mars: Implications of the Late Noachian “icy highlands” model for melting and groundwater recharge on the Tharsis rise
From the Late Noachian period, through the Hesperian, and into the Amazonian periods on Mars, large outflow channels were formed. Many are interpreted to have originated through the catastrophicExpand
Hydrostatic Interfaces in Bodies With Nonhydrostatic Lithospheres
Below the lithospheres of the terrestrial planets, dwarf planets, and moons, density interfaces adjust over geologic time to align with surfaces of constant gravitational potential. It is well knownExpand


Tharsis as a consequence of Mars' dichotomy and layered mantle
[1] The two most striking features of the martian surface topography are the Tharsis rise and the crustal dichotomy. Closely associated with Tharsis are several large volcanoes, active in theExpand
Geological evidence for a migrating Tharsis plume on early Mars
Abstract The Tharsis bulge is the largest magmatic/volcanic center on Mars and in the solar system, having a volume of ~ 3 × 10 8  km 3 , with the majority of its mass emplaced more than 3.7 billionExpand
A numerical study of a mantle plume beneath the Tharsis Rise: Reconciling dynamic uplift and lithospheric support models
[1] The Tharsis Rise is an area of extensive volcanism containing the most significant long-wavelength topographic and areoid anomalies on Mars. The mechanism for supporting this large topographicExpand
Ancient Geodynamics and Global-Scale Hydrology on Mars
The release of carbon dioxide and water accompanying the emplacement of Tharsis magmas may have sustained a warmer climate than at present, enabling the formation of ancient valley networks and fluvial landscape denudation in and adjacent to the large-scale trough. Expand
Internal structure and early thermal evolution of Mars from Mars Global Surveyor topography and gravity.
The strength of the lithosphere beneath the ancient southern highlands suggests that the northern hemisphere was a locus of high heat flow early in martian history and the thickness of the elastic lithosphere increases with time of loading in the northern plains and Tharsis. Expand
A plume tectonics model for the Tharsis province, Mars
Abstract Morphological and structural data from the whole Tharsis province suggest that a number of shallow grabens radially oriented about the Tharsis bulge on Mars are underlain by dykes, whichExpand
Melting in the martian mantle: Shergottite formation and implications for present‐day mantle convection on Mars
Radiometric age dating of the shergottite meteorites and cratering studies of lava flows in Tharsis and Elysium both demonstrate that volcanic activity has occurred on Mars in the geologically recentExpand
Convection Plumes in the Lower Mantle
THE concept of crustal plate motion over mantle hotspots has been advanced1 to explain the origin of the Hawaiian and other island chains and the origin of the Walvis, Iceland-Farroe and otherExpand
Thaumasia: A fossilized early forming tharsis uplift
The structure of the present-day Valles Marineris rift canyons and related features is a consequence of episodic crustal uplift, dominated by two major events. The first of these occurred near theExpand
New Perspectives on Ancient Mars
Mars was most active during its first billion years, and the Tharsis province became a focus for volcanism, deformation, and outgassing of water and carbon dioxide in quantities possibly sufficient to induce episodes of climate warming. Expand
