TLDR
In this article, the authors used topographic information, surface structures and construction of the Martian Tharsis bulge to estimate the previous stresses across the low-lying peripheral margins of the crustal blocks in terms of simple compensation models.Citations

Orientation, relative age, and extent of the Tharsis Plateau ridge system. [volcanic and tectonic regions on Mars]
T. R. Watters,T. A. Maxwell +1 more
TL;DR: The Tharsis ridge system is roughly circumferential to the regional topographic high of northern Syria Planum and the major ThARSis volcanoes as discussed by the authors. But the ridge system has orientations that deviate from the regional trends.

New evidence for a magmatic influence on the origin of Valles Marineris, Mars
James M. Dohm,Jean-Pierre Williams,Robert C. Anderson,Robert C. Anderson,Javier Ruiz,Patrick C. McGuire,Goro Komatsu,Alfonso F. Davila,J. C. Ferris,Dirk Schulze-Makuch,Victor R. Baker,William V. Boynton,Alberto G. Fairén,Trent M. Hare,Hirdy Miyamoto,Kennth L. Tanaka,Shawn J. Wheelock +16 more
TL;DR: In this article, the authors show that the complex geological evolution of Valles Marineris, Mars, has been highly influenced by the manifestation of magmatism (e.g., possible plume activity).
Journal ArticleDOI
Tectonics of Tharsis Dorsa on Mars
TL;DR: In this paper, it was shown that the radial compressional forces generated by the tendency for downslope movement of surface strata, vertical volcanic intrusions and traction of mantle spreading beneath Tharsis were transmitted through the lithosphere to form peripheral mare ridge zones.
Journal ArticleDOI
New Martian Paradigms
TL;DR: Several interrelated paradigms concerning the nature and the evolution of Mars are discussed in this article, such as an impact origin of the northern lowland, Mars as a water-rich planet, former oceans, a warm wet climate on early Mars, and the possibility of ancient life on Mars.
Journal ArticleDOI
Tharsis block tectonics on Mars
TL;DR: The concept of block tectonics provides a framework for understanding many aspects of Tharsis and adjoining structures as mentioned in this paper, which is manifested partly by mantle-related doming and partly by response to loading by subsequent volcanic construction.

Convection Plumes in the Lower Mantle
TL;DR: The concept of crustal plate motion over mantle hotspots has been advanced to explain the origin of the Hawaiian and other island chains and the origin the Walvis, Iceland-Farroe and other aseismic ridges as discussed by the authors.
Book ChapterDOI
Plate Motions and Deep Mantle Convection
TL;DR: In this article, a scheme of deep mantle convection is proposed in which narrow plumes of deep material rise and then spread out radially in the asthenosphere, and thus their strikes show the direction the plates were moving as they were formed.

Tharsis province of Mars: Geologic sequence, geometry, and a deformation mechanism
TL;DR: In this article, a deformation model is proposed in which a first-order mantle convection cell caused early subcrustal erosion and foundering of the low third of the planet.
Journal ArticleDOI
Tectonism and volcanism of the Tharsis region of Mars
TL;DR: The Tharsis region of Mars, where the planet's largest shield volcanoes are located, is at the center of a fracture system that extends over almost half the surface of the planet as discussed by the authors.

Gravity fields of the terrestrial planets: Long‐wavelength anomalies and tectonics
Roger J. Phillips,Kurt Lambeck +1 more
TL;DR: In this article, the authors discuss the gravity and topography data available for four terrestrial planets (earth, moon, Mars, and Venus), with particular emphasis on drawing inferences regarding the relationship of long-wavelength anomalies to tectonics.
