Corona
Ovda Regio, Venus

This Magellan view of Ovda Regio shows a region at least 250 kilometers across characterized by a series of radial and concentric scarps and ridges. These features are a result of intense faulting and fracturing. The relatively smooth center of this corona measures 80 kilometers across and is roughly 3 kilometers lower in elevation than the surrounding ridges.

This tectonically disrupted zone is located near the center of a smooth volcanic plain within Ovda Regio. Several episodes of deformation are apparent. Many of the concentric fractures and graben formed first, and then were faulted by the prominent radial fault system. Several irregular volcanic pits are visible on the flanks of this structure. Fracturing here may have formed when the region was uplifted and then collapsed downward. One possible interpretation is that this area is a collapsed volcanic feature.
