Geologic Map of the Mylitta Fluctus Quadrangle (V-61), Venus

By Mikhail A. Ivanov and James W. Head, III


thumbnail view of map

The Magellan spacecraft orbited Venus from August 10, 1990, until it plunged into the Venusian atmosphere on October 12, 1994. Magellan Mission objectives included (1) improving the knowledge of the geological processes, surface properties, and geologic history of Venus by analysis of surface radar characteristics, topography, and morphology and (2) improving the knowledge of the geophysics of Venus by analysis of Venusian gravity.

The Mylitta Fluctus quadrangle (V-61) is in the southern hemisphere of Venus and extends from lat 50° to 75° S. and from long 300° to 360° E. The northern third of the quadrangle covers the southern part of Lavinia Planitia, which represents a class of equidimensional lowlands on Venus (Bindschadler and others, 1992b) and is as deep as about 1.5–2 km below mean planetary radius. The southeastern part of the map area shows the western part of the upland of Lada Terra, the summit of which is about 3 km above mean planetary radius.
