Magellan images confirm that volcanism is widespread and has been fimdamentally important in the formation and evolution of the crust of Venus. High-resolution imaging data reveal evidence for intrusion (dike formation and cryptodomes) and extrusion (a wide range of lava flows). Also observed are thousands of small shield volcanoes, larger edifices up to several hundred kilometers in diameter, massive outpourings of lavas, and local pyroclastic deposits. Although most features are consistent… Expand
Small volcanic edifices and volcanism in the plains of Venus
The most widespread terrain type on Venus consists of volcanic lowland plains. Several styles of volcanism are represented in the plains. The most extensive volcanic units consist of flood lavas, theExpand
Venus Tectonics: Initial Analysis from Magellan
TLDR
Tectonic features on Venus are unlike those in Earth's oceanic regions in that strain typically is distributed across broad zones that are one to a few hundred kilometers wide, and separated by stronger and less deformed blocks hundreds of kilometers in width, as in actively deforming continental regions on Earth.

Sapas Mons, Venus: evolution of a large shield volcano
Magellan radar image data of Sapas Mons, a 600 km diameter volcano located on the flanks of the Arla Rise, permit the distinction of widespread volcanic units on the basis of radar properties,Expand

A preliminary analysis of a global survey of Magellan data covering over 90% of the surface and designed to document the characteristics, location, and dimensions of all major volcanic features onExpand
Venus tectonics: An overview of Magellan observations
The nearly global radar imaging and altimetry measurements of the surface of Venus obtained by the Magellan spacecraft have revealed that deformational features of a wide variety of styles andExpand
Styles of deformation in Ishtar Terra and their implications
Ishtar Terra, the highest region on Venus, appears to have characteristics of both plume uplifts and convergent belts. Magellan imagery over longitudes 330°–30°E indicates a great variety of tectonicExpand
Anatomy of a Venusian hot spot - Geology, gravity, and mantle dynamics of Eistla Regio
Eistla Regio is a series of broad swells, each up to a few thousand kilometers in diameter, in the equatorial highlands of Venus. It is characterized by strong positive free-air gravity anomalies,Expand
Volcanism and volatile recycling on a one-plate planet: Applications to Venus
[1] The surface of Venus displays volcanic features indicating eruption of lavas with a wide range of viscosities. We present numerical experiments showing that lithospheric gravitationalExpand
An assemblage of lava fl ow features on Mercury
[1] In contrast to other terrestrial planets, Mercury does not possess a great variety of volcanic features, its history of volcanism instead largely manifest by expansive smooth plains. However, aExpand
Mylitta Fluctus, Venus - Rift-related, centralized volcanism and the emplacement of large-volume flow units
Mylitta Fluctus is a volcanic flow field that covers approximately 300,000 km2 in southern Lavinia Planitia. The flows are typically radar-bright with uniform surface textures. Central channels areExpand

Lakshmi Planum is distinctive and unique on the surface of Venus as an expansive (~2 × 106km2), relatively smooth, flat plateau containing two large shield volcanoes and abundant volcanic plains inExpand
Styles of Volcanism on Venus: New Arecibo High Resolution Radar Data
TLDR
Radar data of Venus provides strong evidence that the mountains in Beta and Eisila Regiones and plains in and adjacent to Guinevere Planitia are of volcanic origin and suggests that heat loss by abundant and widely distributed plains volcanism may be more significant than previously recognized.

Small domes on Venus: Probable analogs of Icelandic lava shields
On the basis of observed shapes and volumetric estimates, we interpret small, dome-like features on radar images of Venus to be analogs of Icelandic lava-shield volcanoes. Using morphometric data forExpand
Volcanoes as possible indicators of tectonic stress orientation — principle and proposal
Abstract A method is proposed for determining the orientation of average tectonic stress, using surface features indicating radial dike patterns of volcanoes. The approximate pattern of radial dikesExpand
Formation of mountain belts on Venus: Evidence for large-scale convergence, underthrusting, and crustal imbrication in Freyja Montes, Ishtar Terra
The Freyja Mottles, Venus, deformation zone consists of a distinctive linear orogenic belt (Freyja Montes), an adjacent plateau, a steep scarp separating the plateau from the North Polar Plains lyingExpand
Intrusive and extrusive growth of the Mount St Helens lava dome
LAVA domes grow by a combination of endogenous (intrusive) and exogenous (extrusive) addition of magma, either as single continuous events1,2 or through a series of relatively small pulses whichExpand
Magmatism at rift zones: The generation of volcanic continental margins and flood basalts
When continents rift to form new ocean basins, the rifting is sometimes accompanied by massive igneous activity. We show that the production of magmatically active rifted margins and the effusion ofExpand
