Sveinsd髏tir Crater and Beagle Rupes (natural colors; credits: Lunexit)
|
Named for J煤l铆ana Sveinsd贸ttir, an Icelandic painter and textile artist, Sveinsd贸ttir Crater superimposed by Beagle Rupes is a distinctive feature on Mercury's landscape. Unusually elliptical in shape, the Crater was produced by the impact of an object that hit Mercury鈥檚 Surface obliquely. More than 600 Km (about 370 miles) long and one of the largest fault scarps on the Planet, Beagle Rupes marks the surface expression of a large thrust fault believed to have formed as Mercury cooled and the entire planet shrank. Beagle Rupes crosscuts Sveinsd贸ttir Crater and has uplifted the easternmost portion (right side portion) of the crater floor by almost a kilometer, indicating that most of the fault activity at Beagle Rupes occurred after the impact that created Sveinsd贸ttir. Crosscutting relationships such as this are used to understand the sequence in time of the different processes that have affected Mercury鈥檚 evolution.
