Abstract
On the basis of a detailed bathymetric map of the area of the southeastern part of the Magellan Mountains constructed on the results of multi-beam echolocation, the authors performed a lineament analysis of the relief, distinguished linear relief objects, measured their azimuths, and built a rose-diagram of the direction of the area's lineaments. Models of the deep and near-surface deformation field of the area with the selection of blocks with the predominant stretching and the predominant compression are constructed. Along the lines of changing the sign of stress (block boundaries), block movements occur. The directions of the block boundaries are compared with the direction of the lineaments, and a conclusion is made about their spatial and genetic relationship. Systems of the direction of linear landforms and boundaries of deep and near-surface blocks partially correspond to four main systems of the global regmatic network indicating a significant influence of the latter on the structural plan of the area. The redistribution of stress values is associated with modern geological processes that lead to the formation of new features of the bottom relief and partial destruction of the old guyot surfaces.
