Abstract

Gravity, magnetic- and electromagnetic surveys of Drake Passage during the Ukrainian Antarctic expeditions 1997-2004 years provided new geophysical data for many West Antarctica bottom structures. New obtained data on the geophysical fields distribution for the tectonic structures of the West Antarctica lithosphere enabled to distinguish the age of some blocks formation and separate local crustal inhomogeneities, specify the schemes of the structural division of the continental margin of Antarctica. Great effect of tectonic factors influence on sediment formation (from 100m to 2,5km thick) and existence of some intrusions and tectonically active fracture zones in Drake Passage has been detected and defined more exactly.
