NASA Photo ID: S90-49779 File Name: 10063350.jpg Film Type: 4x5 BW Date Taken: 10/09/90 Title: Magellan radar image of Danu Montes in Lakshmi Region of Venus Description: This Magellan radar mosaic image is of part of the Danu Montes in the Lakshmi Region of Venus. The area in the image is located at 329.6 degrees east longitude and 58.75 degrees north latitude. This image shows an area 40 kilometers (km) (19.6 miles) wide and 60 km (39.2 miles) long. Danu Montes is a mountain belt located at the southern edge of the Ishtar Terra highland region. It rises one to three kilometers above a flat plain to the north known as Lakshmi Planum. On the basis of Pioneer Venus, Arecibo and Venera data, Danu Montes and the other mountain belts surrounding Lakshmi Planum have been interpreted to be orogenic belts marking the focus of compressional deformation, much like the Appalachian and Andes ranges on Earth. In the upper right part of this image, relatively bright, smooth-textured plains of Lakshmi Planum are seen to embay the heavily deformed mountain range to the south. In the mountain range south of these plains the geology is dominated by abundant faults at multiple angles and showing various cross-cutting relationships. In the northern part of the mountain the surface is dominated by sinuous, west-northwest trending troughs less than a kilometer (0.6 mile) in width, separated by narrow, flat regions. The prominent bright and dark feature trending across the bottom part of the image is a linear trough about 5 km (3.1 miles) located near the crest of the mountain range. South of the mountain crest, additional deformation is seen trending both parallel and perpendicular to the structures in the other parts of the mountain belt. Jet Propulsion Laboratory (JPL) alternate number is P-36643. Subject terms: CRATERS FAULTS MAGELLAN SPACECRAFT (NASA) RADAR DATA VENUS (PLANET) VENUS SURFACE VOLCANOES
