The Laudalkammen is an ice-free mountain ridge in the Kottas Mountains ( Neuschwabenland , East Antarctica ), which extends over a length of 2.5 km in a north-south direction and reaches a maximum height of 1445 m above sea level. To the north the ridge dissolves into individual nunataks , including the small Weigelnunatak , in the south it is dominated by the 1962 m high Haukelandnuten .
geology
The ridge consists mainly of pink granite , which, in contrast to the rocks in neighboring parts of the Kottas Mountains, is not metamorphically overprinted. A dark gray diorite appears in the granite as a mighty corridor . Both the granite and the corridor show signs of weak deformation in the form of extensive foliation . The most recent tectonic elements can be observed at the northern end of the laudal ridge, almost vertical faults .
Discovery and Exploration
On January 20, 1939, the Kottas Mountains were discovered during image flight I of the German Antarctic Expedition 1938/39 , but were not photographically documented due to the failure of the starboard camera. A naming of individual peaks and nunataks was not made. During the Norwegian Antarctic Expedition 1956–1960, the area was recorded photogrammetrically for the first time and control points were also measured for more precise orientation. On the Norwegian map series of the Dronning Maud Land, published since 1959, many objects in the Kottasberg were named after Norwegian resistance organizations and fighters from the Second World War. The namesake for the Laudalkammen is the officer Arne Laudal (1892-1944), a leader of the resistance group Milorg , who was executed on May 9, 1944 by the German occupiers.
The first geological research was carried out by British geologists in the 1960s. Between 1985 and 1994 several German expeditions visited the area and a detailed geological map was created.
