Plains tectonism on Venus - The deformation belts of Lavinia PlanitiaThe belts of the Lavinia Planitia region of Venus are discussed in detail with reference to high-resolution radar images from the Magellan spacecraft. Two types of deformation belts are identified: ridge belts and fracture belts. Ridge belts are composed of parallel ridges, each a few hundred meters in elevation, that are interpreted as folds. Typical fold spacings are 5-10 km. Fracture belts are dominated by intense faulting, with faults in some instances paired to form narrow grabens. The formation of ridge and fracture belts is explored using simple models.
