Isostasy, flexure, and dynamic topography
Article history: Received 12 January 2016 Received in revised form 26 May 2016 Accepted 27 May 2016 Available online 31 May 2016 A fundamental scientific question is, what controls the Earth's topography? Although the theoretical principles of isostasy, flexure, and dynamic topography arewidely discussed, the parameters needed to apply these principles are frequently not available. Isostatic fa...
متن کاملThe Effects of Dynamic Topography and Thermal Isostasy on the Topogra- Phy and Geoid of Venus
Introduction: The Venusian geoid, gravity field, and topography have been used in a variety of applications and are the primary sources of information about the internal structure of the planet. We focus on the relationship between the geoid and topography to determine both the support mechanism for the topography and lithospheric density structure. Magnitude of Dynamic Topography: The long-wav...
متن کاملFlexural Response to Sediment Erosion and Unloading at Valles Marineris,
Introduction: The origin and evolution of the Valles Marineris canyon system and its stacks of interior layered deposits (ILD) on Mars remains as one of the most debated topics in Martian tectonics. The subtle broad topographic uplift around the periphery of the canyon system conflicts with the uplifted flanks predicted by models of normal faulting [1]. This uplift is obscured in the east and w...
متن کاملA comparison between two solution techniques to solve the equations of linear isostasy
In this paper we compare two models to compute the isostatic response of the Earths lithosphere to an external load. The lithosphere is modeled as a linear elastic solid. The two models differ in the mathematical formulation of the problem, their applicability in the incompressible limit, the choice of the finite elements used for discretization, and the solution strategy for the arising algebr...
متن کاملLithospheric flexure and the evolution of the dichotomy boundary on Mars
[1] The boundary of the Martian crustal dichotomy in the eastern hemisphere is one of the most striking topographic features on the planet. The long wavelength topography of much of the boundary is expressed by a broad rise and an arched ramp that slopes downward from the southern highlands into the northern lowlands and often ends in a steep scarp. Lithospheric flexure of the southern highland...
