摘要：

Based on an analysis of global digital models, the distribution of fracture zones of the oceanic crust, global and regional models of evolution, and published geological and geophysical data, the structural features of the ocean floor in the junction area of the Indian and Atlantic oceans are considered. Tectonic zoning of the region's crust has been carried out. Heterogeneous blocks of the lithosphere with crust formed on different spreading ridges, separated by structural boundaries, which are pseudofaults, fixing traces of propagating rift zones, jumping and cessation of spreading ridges are identified. The main stages in the evolution of the lithosphere associated with the activation of plume magmatism and kinematic reorganizations of plate boundaries are identified.
