Lithospheric failure on Venus
We develop a predictive model which has the ability to explain a postulated style of episodic plate tectonics on Venus, through the periodic occurrence of lithospheric subduction events. Present-day incipient subduction zones are associated with the existence of arcuate trenches on the Venusian lithosphere. These trenches resemble terrestrial subduction zones, and occur at the rim of coronae, u...

15 صفحه اولMapping crustal thickness using marine gravity data: Methods and uncertainties
Crustal thickness is a critical parameter for understanding the processes of continental rifting and breakup and the evolution of petroleum systems within passive margins. However, direct measurements of crustal thickness are sparse and expensive, highlighting the need for methodologies using gravity anomaly data, jointly with other geophysical data, to estimate crustal thickness. We evaluated ...
متن کاملTessera terrain and crustal plateaus , Venus
Many workers assume that tessera terrain—marked by multiple tectonic lineaments and exposed in crustal plateaus—comprises a global “onion skin” on Venus. A growing body of structural, mechanical, magmatic, gravitational-topographic, and geologic evidence indicates that tesserae record the local interaction of individual deep-mantle plumes with an ancient, globally thin Venusian lithosphere, res...
متن کاملCrustal Plateau Collapse on Venus: Evidence from the Pasom-mana
Introduction: Over the past several years, a number of workers have offered compelling evidence that Venusian crustal plateaus were created by mantle upwelling [1], [2], [3], [4]. Recent geophysical modeling has further suggested that, on Venus, an initially uncompensated crustal plateau created by upwelling should decay into a torroidal shape in three dimensions and a ring shape in map view [5...
