what kind of plate boundary exists at the southeast indian ridge
Principal strain orientations (minimum horizontal compressionâex and maximum horizontal compressionâey) were established at three different types of plate tectonic boundary: two transform faults, an oceanic ridge located on the Southeast Indian Ridge and a trench located close to the South Sandwich Archipelago.ocation of the studied zones in the plate tectonic context. (A) Location of the ridge and transform fault zones on the boundary between the Australian and the Antarctic plates. (B) Location of the trench zone, the South Sandwich Trench, eastern boundary between the Sandwich and South American plates.
