Geomorphologic map of Indian and Pacific sectors of the Antarctic

Abstract

A new geomorphic map of Indian and Pacific sectors of the Antarctic is compiled, scale 1:5000000. The legend is based on the genesis and describes geotectures, morphostructures, morphosculptures and planation surfaces, dissection and individual sea floor forms. According to the data on sediment yield and sedimentation rate, some sea floor parts are indicated having completely planated bottom and tectonic forms mantled by sediments.

Special features of the morphostructures distribution are revealed within Indian and Pacific sectors of the Antarctic.
