Abstract: The Larsemann hills are a series of gneiss islands and peninsulas extending into Prydz Bay, with an ice free area of approximately 200 km2 at 69°21′S 69°28′S and 76°00′E 76°25′E on the Ingrid Christensen Coast of Princess Elizabeth Land in East Antarctica. The area lies in the pole permafrost zone, aeolian action is very frequently and generally. The characteristics of modern landform are controled by periglacial processes. Because of the short history of ice free area and the relatively stable older Archean Shield, the weathering process is very weak with mainly mechanical weathering, especially frost process. The major geomorphic types consist of aeolian landforms. periglacial landforms,glacial landforms, lake landforms, coast landforms and geological structure landforms, etc. The deposited landforms have not been developded successfully and fully. The landforms on the west hills are relatively young. The direction of glacial retreat is from NE to SW, according to the distribution of glacial relics, i. e. , moraines and rub traces. Islands. peninsulas and ice-land transition zone are three geomorphic regions.

Key words: Larsemann Hills, geomorphic factors, landforms, regional composition
