▪ Abstract Earth, Venus, and Mars all exhibit populations of giant (radiating, linear, and
arcuate) mafic dike swarms hundreds to> 2000 km in length. On Earth the dikes are exposed …

Shear zones are the most ubiquitous features observed in planetary surfaces. They appear
as a jagged network of faults at the observable brittle surface of planets and, in geological …

The surface area of Venus (∼ 460× 106km2) is∼ 90% of that of the Earth. Using Magellan
radar image and altimetry data, supplemented by Venera-15/16 radar images, we compiled …

Mantle convection on Venus is likely to occur in the regime known as stagnant lid
convection. We investigate this regime for internally heated convection with temperature-and …

The surface of Venus displays several tectonized terrains in which the morphologic
characteristics of the original materials are almost completely erased by superposed tectonic …

Novae and coronae are large volcanotectonic features on Venus, with a contentious and
possibly non-unique origin and enigmatic relationship. Their formation is most commonly …

Geological map** principles have been applied across planet Earth since William Smith's
initial 1815 map. During the Space Age, these principles were applied to smaller moons and …

Detailed map** in a 14,000,000 km2 area of northwestern Guinevere Planitia and
northern Beta Regio bounded by 264°–312° E, 24°–60° N has revealed thousands of long …

Novae are “radially fractured centers” 100–300 km in diameter, and 64 have been identified
on Venus. Dense radial fracturing and upraised topography are common, and massive …

Parga Chasmata is a 10,000 km long rift system on Venus with abundant coronae
(enigmatic circular tectonomagmatic features). In order to further investigate the rift-corona …
