![]() ![]() Lakshmi is situated 3 to 5 km above the mean planetary radius and is surrounded on all sides by bands of mountains interpreted to be of compressional tectonic origin. Lakshmi Planum, a broad smooth plain located in western Ishtar Terra and containing two large oval depressions (Colette and Sacajawea), has been interpreted as a highland plain of volcanic origin. Lakshmi Planum: A distinctive highland volcanic province “I will encourage interdisciplinary articles in Eos that deal with water issues and the role of hydrology within a broad spectrum of problems and disciplines.†“Hydrology is not a stand-alone science,†he said. Among his goals as editor, Lakshmi will seek to portray hydrology as an integrative science. Venkat Lakshmi, an assistant professor in the Department of Geological Sciences at the University of South Carolina, has begun his 3-year term with Eos as the hydrology section editor. A tectonic scheme of the Lakshmi structure formation is presented. It is noted that the characteristics of the Lakshmi Planum and it bounding mountains suggest that this ensemble is a giant hot-spot structure with the intensive volcanism and radial tectonic spreading, leading to the piling up of the crust material at the structure periphery. The compressional deformations on its periphery are explained by seeing the Lakshimi strucutre as a locus of convergence, and the volcanic activity of the central part of the structure is explained by the melting of the bottom of the crust at the place of its convergency thickening. Special attention is given to the origin of the Lakshmi structure. The structures of the Lakshmi Planum and its surrounding mountains are described. ![]()
