  author={W. McKinnon and P. Schenk and A. Dombard},
Mountains are distributed across the surface of Io, the fiercely tidally heated moon of Jupiter. The large crustal thicknesses implied by their great heights can be reconciled with Io's high heat flow, if most of the heat escapes directly via volcanic eruptions (the heat-pipe model), but the origin of the mountains has remained obscure. Recent images show that many of Io's mountains are tilted blocks undergoing tectonic collapse, and we propose here that the volcanic heat-pipe (and continuous… Expand
Formation of mountains on Io: Variable volcanism and thermal stresses
Abstract Thermal stresses are potentially important drivers of Io's tectonics and mountain building. It has been hypothesized that sustained local or regional shut down of heat-pipe volcanism on IoExpand
Effects of faulting on crustal stresses during mountain formation on Io
Abstract The vast majority of mountains observed on Io are tectonic, upthrusted blocks – a product of compressional forces. The mechanism behind their formation is generally understood to be relatedExpand
Mountain building on Io driven by deep faulting
The high relief on Jupiter’s moon Io has been linked to compression due to global subsidence. Simulations show that Io’s mountains may form along thrust faults that initiate at the lithosphere’s baseExpand
Global distribution of volcanic centers and mountains on Io: Control by asthenospheric heating and implications for mountain formation
Abstract Jupiter's moon Io possesses numerous tectonic mountains in addition to its ubiquitous volcanoes and volcanic features. Remarkably, a distinct global anticorrelation exists between theExpand
Magma ascent pathways associated with large mountains on Io
Abstract While Jupiter's moon Io is the most volcanically active body in the Solar System, the largest mountains seen on Io are created by tectonic forces rather than volcanic construction. PervasiveExpand
The mountains of Io: Global and geological perspectives from Voyager and Galileo
To search for local and global scale geologic associations that may be related to the internal dynamics of lo, we have completed a global catalog of all mountains and volcanic centers. We haveExpand
Conditions for the onset of plate tectonics on terrestrial planets and moons
Abstract Plate tectonics on Earth is driven by the subduction and stirring of dense oceanic lithosphere into the underlying mantle. For such a regime to exist on any planet, stresses associated withExpand
Volcanism on Io
Jupiter's moon Io is the most volcanically active body in the solar system. Spacecraft images showed a surface dotted with volcanoes, volcanic plumes rising hundreds of kilometers above the surface,Expand
Mountains on Io: High‐resolution Galileo observations, initial interpretations, and formation models
During three close flybys in late 1999 and early 2000 the Galileo spacecraft acquired new observations of the mountains that tower above Io's surface. These images have revealed surprising variety inExpand
Spatial distribution of volcanoes on Io: implications for tidal heating and magma ascent
Abstract Extreme volcanism on Io results from tidal heating, but its tidal dissipation mechanisms and magma ascent processes are poorly constrained. Here we analyze the distribution of volcanicExpand


Background heatflow on hotspot planets: Io and Venus
On planets where most of the heat is transported to the surface by igneous activity (extrusive volcanism or near-surface intrusions), the surface heatflow at localities well away from regions ofExpand
Joints in Venusian lava flows
Venusian plains regions, as imaged by the Magellan spacecraft, display many styles of tectonic and volcanic deformation. Radar images of several areas of the volcanic plains reveal polygonal patternsExpand
Evaluation of models for the formation of chaotic terrain on Europa
Chaotic terrain on Europa is interpreted to be the result of the breakup of brittle surface materials over a mobile substrate. Two end-member models have been proposed for the mobile substrate: aExpand
Mountains and Calderas on Io: Possible Implications for Lithosphere Structure and Magma Generation
Abstract The combination of Voyager images and newly acquired Galileo images with low illumination and resolutions ranging from 2 to 6 km/pixel now allows determination of the global distribution ofExpand
Origin of mountains on Io by thrust faulting and large-scale mass movements
Voyager stereoimages of Euboea Montes, Io, indicate that this mountain formed when a large crustal block was uplifted 10.5 kilometers and tilted by approximately 6 degrees. Uplift triggered a massiveExpand
▪ Abstract Io, innermost of Jupiter's large moons, is one of the most unusual objects in the Solar System. Tidal heating of the interior produces a global heat flux 40 times the terrestrial value,Expand
Magma transport of heat on Io: A mechanism allowing a thick lithosphere
Models indicate that the high heat flow from Io would result in a very thin (approximately 5 km) silicate lithosphere overlying a molten interior, if all heat was transported through the lithosphereExpand
Tectonic deformation of Galileo Regio and limits to the planetary expansion of Ganymede
Galileo Regio is the largest and most prominent unit of dark, ancient, heavily cratered terrain on Ganymede. Its major tectonic feature, an arcuate system of rimmed furrows, formed very early, asExpand
High‐temperature deformation of dry diabase with application to tectonics on Venus

Galileo at Io: results from high-resolution imaging.
During late 1999/early 2000, the solid state imaging experiment on the Galileo spacecraft returned more than 100 high-resolution images of volcanically active Io, observing an active lava lake, an active curtain of lava, active lava flows, calderas, mountains, plateaus, and plains. Expand
