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 on Venus has revealed over 1660 landforms and deposits. These include over 550 shield fields (concentrations of small volcanoes <20 km in diameter), 274 intermediate volcanoes between 20 and 100 km diameter with a variety of morphologies, 156 large volcanoes in excess of 100 km diameter, 86 calderalike… Expand
Relationship of coronae, regional plains and rift zones on Venus
Abstract Coronae and rifts are the most prominent volcano-tectonic features on the surface of Venus. Coronae are large radial–concentric structures with diameters of 100 to over 1000 km. They haveExpand
Large-scale volcanism associated with coronae on Venus
The formation and evolution of coronae on Venus are thought to be the result of mantle upwellings against the crust and lithosphere and subsequent gravitational relaxation. A variety of otherExpand
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
Evolution of large shield volcanoes on Venus
[1] We studied the geologic history, topographic expression, and gravity signature of 29 large Venusian shield volcanoes with similar morphologies in Magellan synthetic aperture radar imagery. WhileExpand
An unusual volcano on Venus
Materials that issued from an unusual Venusian volcano produced (1) a complex domical structure about 100 km across with thick, broad flow lobes up to 41 km wide, (2) an extensive sheet of thickExpand
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
Formation and evolution of volcanic edifices on the Dione Regio rise, Venus
Mapping of Dione Regio, Venus, a regional highland 1200 by 2700 km in size with mean elevation of 6052 km located in the southern hemisphere to the NW of Lavinia Planitia, reveals a regionExpand
Artemis, Venus: The largest tectonomagmatic feature in the solar system?
New geologic mapping reveals that Artemis, a unique 2400-km-diameter feature on Venus, is much larger than previously recognized, including a wide outer trough (>5000 km diameter), a radial dikeExpand
A Stratigraphic Study of Small Volcano Clusters on Venus
Recently proposed global stratigraphy and geologic history models have led to two end member volcanic evolution models for Venus: a “directional” model that proposes Venus has progressed through aExpand
The morphology and evolution of coronae on Venus
Coronae on Venus are large, circular to ovoidal surface features that have distinctive tectonic, volcanic, and topographic expressions. They range in diameter from less than 200 km to at least 1000Expand

TLDR
Magellan images confirm that volcanism is widespread and has been fimdamentally important in the formation and evolution of the crust of Venus and reveals a number of large pancake-like domes are morphologically similar to rhyolite-dacite domes on Earth. Expand

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.

Venus: Limited extension and volcanism along zones of lithospheric weakness
Three global-scale zones of possible tectonic origin are described as occurring along broad, low rises within the Equatorial Highlands on Venus (lat 50° N. to 50° S., long 60° to 310°). The twoExpand
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
Geophysical models for the formation and evolution of coronae on Venus
Coronae are large circular features on Venus characterized by an annulus of concentric tectonic features, interior fracturing, volcanism, and generally upraised topography. They are suggested to formExpand
Global distribution and characteristics of coronae and related features on Venus: Implications for origin and relation to mantle processes
Coronae on Venus range from 60 to over 2000 km across and are characterized by a complex range of morphologies. The annuli around coronae range from about 10 to 150 km across and have tectonicExpand
