Loading of the lithosphere of Mars by the Tharsis rise explains much of the global shape and long-wavelength gravity field of the planet, including a ring of negative gravity anomalies and a topographic trough around Tharsis, as well as gravity anomaly and topographic highs centered in Arabia Terra and extending northward toward Utopia. The Tharsis-induced trough and antipodal high were largely in place by the end of the Noachian Epoch and exerted control on the location and orientation of… Expand

Topographic Change of the Dichotomy Boundary Suggested by Crustal Inversion
Linear negative gravity anomalies in Acidalia Planitia along the eastern edge of Tempe Terra and along the northern edge of Arabia Terra have been noted in Mars Global Surveyor gravity fields. OnceExpand
Anomalous aspects of Martian geology are explained by a theory that incorporates the onset and termination of a core dynamo, associated with an early regime of plate tectonics during the first fewExpand
Geophysical evidence supports migration of Tharsis volcanism on Mars
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 proposedExpand
Introduction. Throughout the recorded history of Mars, liquid water has shaped its landscape into a number of distinct morphologic types, including prominent features such as the circum-Chryse andExpand
Martian rifts: Structural geology and geophysics
Large extensional tectonic surface structures on Mars are investigated on the basis of image and topographic data. These features have lengths of up to 1400 km, typical widths of tens of kilometers,Expand
Hemispheres Apart: The Crustal Dichotomy on Mars
The hemispheric dichotomy is a fundamental feature of Mars, expressed by a physiographic and geologic divide between the heavily cratered southern highlands and the relatively smooth plains of theExpand
Thrust fault vergence directions on Mars: A foundation for investigating global-scale Tharsis-driven tectonics
[1] Insight into the mechanical and thermal structure of the Martian lithosphere and the character of Tharsis-driven tectonics is gained from detailed mapping of the global distribution of thrustExpand
Late Tharsis formation and implications for early Mars
The rotational figure of Mars (that is, its equilibrium shape) and its surface topography before Tharsis formed, when the spin axis of the planet was controlled by the difference in elevation between the northern and southern hemispheres (hemispheric dichotomy), is calculated. Expand
Deltas and valley networks on Mars: Implications for a global hydrosphere
Deltaic depositional systems are the most prominent evidence suggesting the existence of long-lasting standing bodies of water on Mars. Due to this genetic link, Martian deltas are fundamental forExpand
Variations in Martian Lithospheric Strength Based on Gravity/Topography Analysis
We applied localized gravity/topography admittance and correlation analysis, as well as the Markov chain Monte Carlo method, to invert for loading and flexural parameters of 21 subregions on MarsExpand


Evolution of the Tharsis Province of Mars: The importance of heterogeneous lithospheric thickness and volcanic construction
The Tharsis province of Mars is a broad region characterized by anomalously elevated topography, a positive free-air gravity anomaly, and extensive volcanic and tectonic activity. The evolution ofExpand
The role of lithospheric stress in the support of the Tharsis Rise
The Tharsis rise on Mars is a broad topographic high covered by volcanic plains and capped by large volcanoes. The geoid high associated with Tharsis shows that shallow isostatic compensation is notExpand
Lithospheric-scale buckling and thrust structures on Mars: The Coprates rise and south Tharsis ridge belt
Detailed photogeologic mapping documents for the first time the deformation sequence of the Coprates rise. Materials of Middle Noachian through perhaps Early Hesperian age were involved in theExpand
Voluminous volcanism on early Mars revealed in Valles Marineris
The relative rates and importance of impact cratering, volcanism, erosion, and the deposition of sediments to the early geological history of Mars are poorly known. That history is recorded in theExpand
Geomorphic evolution of the Martian highlands through ancient fluvial processes
Craters in the Martian highlands are preserved in various stages of degradation. As a result of an erosional process active from the Middle Noachian (4.40–3.92 b.y.) through the Hesperian (3.55–1.8Expand
Mars without Tharsis
The significant power in the Martian gravitational field due to the Tharsis rise may mask or modify gravitational signatures that contain important information on Martian geophysical processes. InExpand
The Martian drainage system and the origin of valley networks and fretted channels
Outflow channels provide strong evidence for abundant water near the Martian surface and an extensive groundwater system. Collapse of the surface into some channels suggests massive subsurfaceExpand
Support of long‐wavelength loads on Venus and implications for internal structure
A thin-shell formulation for computing stress distributions on the surfaces of one-plate planets is developed. The lithospheric model includes laterally varying density anomalies at two depths,Expand
