The East Antarctica may be subdivided into 5 regions: basins and troughs (<-100 m), plains (-100-400 m), hills (400-1000 m), low mountains (1000-1500 m), middle mountains (>1500 m). There are evidences of at least two stages of subglacial relief formation. The first stage corresponds to platform type development with weak tectonic activity. The second one is characteristic of mobile folded zones where tectonic movements had large amplitudes and strong spatial differentiation (especially during Cenozoic era).
