| Summary: | The paper gives the brief characteristics of the main bottom morpho-structures, revealed as the result of geomorphological analysis and according to separate geophysical data taken by expeditions of different countries. Differences in the type of the earth's crust under ocean floor serve as the main taxonomic principle. Thus the shelf on the margin of Antarctica is characterized by purely continental features. To the transition continental-oceanic area belong the continental slopes, the zones of island arcs and the basins of marginal seas. Structure areas of the oceanic crust are represented by gigantic depressions of oceanic basins and arched uplifts of oceanic swells, by linear folded-block elevations of median ridges, by oceanic trenches and their marginal swells. Seven bathymetrical, geomorphological and tectonic maps have been compiled for "The Atlas of the Antarctic". |
