Tessera terrain and crustal plateaus , Venus

چکیده
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, resulting in local regions of thickened crust.

Structural and Kinematic Analysis of Eastern Ovda Regio,Venus: Implications for Crustal Plateau Formation
Crustal plateaus on Venus constitute one of that planet’s most intriguing tectonic features. They host so-called “tessera” terrain, or deformed crust exhibiting two or more sets of intersecting tectonic lineaments, which comprises ∼8% of Venus’ surface. Major questions surrounding crustal plateaus and tessera terrain include: (1) What is the nature of crustal plateau deformation? What structure...
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...

متن کاملIs There a Genetic Association between Ribbon Tessera Terrain and Shield
Introduction: Venus host two distinctive terrains, one tectonic, the other volcanic. These two terrain types, ribbon tessera terrain and shield terrain are both extensively preserved across the surface of Venus, and they might also show a spatial correlation, which may, in turn reflect a genetic relationship. Geology: Ribbon tessera terrain (rtt) represents the oldest locally exposed unit acros...
متن کاملFortuna Tessera, Venus Evidence of Horizontal Convergence and Crustal Thickening
Structural and tectonic patterns mapped in Fortuna Tessera are interpreted to reflect a change in the style and intensity of deformation from east to west, beginning with simple tessera terrain at relatively low topographic elevations in the east and progressing through increasingly complex deformation patterns and higher topography to Maxwell Montes in the west. These morphologic and topograph...
