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 کاملIsostasy, dynamic topography, and the elevation of the Apennines of Italy
a r t i c l e i n f o a b s t r a c t The elevation of an orogenic belt is commonly related to crustal/lithosphere thickening. Here, we discuss the Apennines as an example to show that topography at a plate margin may be controlled not only by isostatic adjustment but also by dynamic, mantle-driven processes. Using recent structural constraints for the crust and mantle we find that the expected...
متن کاملFlexure of Venusian lithosphere measured from residual topography and gravity
[1] The elastic lithosphere thickness Te for various locations on Venus is estimated by modeling lithospheric flexure associated with rifts, coronae, chasmata, and the moats visible around certain large volcanoes. By modeling flexure using the residual topography, a range of elastic thicknesses was found, from around 10 to 40 km or greater. A number of these values are not well-determined and o...
