Definition
Materials of ridged plains (pr) have the morphology of lava plains that are often deformed by broad (5–10 km wide) and long (several tens of kilometers) linear and curvilinear ridges (Fig. 1). The radar backscatter cross-section of ridged plains is noticeably higher than that of the surrounding regional plains (McGill and Campbell 2006) but typically lower than that of tessera and densely lineated plains.
Examples of ridged plains on Venus at the Magellan resolution (100–200 m/px). (a) Central portion of Lavinia Planitia, C1-MIDR 45S350, centered 38.3°S, 347.5°E. (b) Region of the ridge belt “fan,” C1-MIDR 60 N208, centered 62.1°N, 215.4°E. (c) Area to the north of Ovda Regio, C1-MIDR 15 N077, centered 15.0°N, 78.7°E. (d) Ausra Dorsa to the south of Fortuna Tessera, C1-MIDR 45 N032, centered 48.4°N, 23.9°E (Magellan radar photomaps (NASA/JPL))
