The XU-Fjella is a part of the Heimefrontfjella in Queen Maud Land . It consists of about 20 nunataks , which extend over an area of ​​180 km². The mountains were named after the Norwegian resistance group XU during World War II .

exploration

The XU-Fjella is the highest part of the Heimefrontfjella, which is separated from the other parts of the mountain by wide, crevice-rich glaciers and is therefore difficult to access. The exploration began in the southern summer of 1965/66 by a British expedition that carried out survey work and carried out a geological program. Two German expeditions explored the mountains in 1994 and 2001 and created detailed geological maps.

Over a middle Proterozoic basement of metamorphic rocks lies an overburden of Permian sandstones that has been preserved in remains . The tallest nunatakkers are built from basalts that were mined when the continent Gondwana broke up and the Southern Ocean opened up in the Jura .

Nunatakker

Only the eight largest nunatakkers are named on the Norwegian topographic map. The Norsk Polar Institute named the Nunatakker after Norwegian resistance fighters in World War II.
