The tectonic evolution and importance of Marie Byrd Land, West Antarctica

Introduction Marie Byrd Land (MBL) is a West Antarctica plot important for understanding the evolution of the Antarctic Lift System (WARS). The size of WARS is comparable to other lift systems, but it covers a wide range of ice sheets (LeMasurier, 2008). The MBL includes exposure to long-term behavior of WARS (Cande et al., 2000; Steinberger et al., 2004) and volcanic activity under the ice associated with the system damages the ice sheet in the western Antarctic, It may cause a momentary eruption (Blankenship et al., 1993).

Marie Birdland is the largest volcanic area in Antarctica, about 970 km along the Pacific coast. A lift from the base of the Antarctic Peninsula to the surrounding area of ​​Ross Island can be seen along the northern end of the Rift Valley. Numerous major shield volcanoes are emphasized through ice, including Sidley Mountain, the highest volcano in Antarctica. Although many volcanoes may be relatively young and active (Berlin, Taka, Weshe, Mount Seaple), other volcanoes such as Andrew Mountain and Hampton Mountain have a history of over 10 million years Remains left untouched architectural form

In the new NASA's research, we have added evidence that the geothermal heat source called the mantle plum is deep in the Maryborough area of ​​Antarctica and explains the melting of the lake and river under the ice floor. Heat source is not a new threat to the ice sheets of the Western Antarctic or an increase in threat but explains why the ice sheets collapsed rapidly in the early stages of rapid climate change and why today is so unstable It may be useful for. Experiments done at Oxford University show that the structural plate is weaker than previously thought. This finding explains the ambiguity of laboratory work and scientists have come to believe that these rocks look stronger than they do in nature. This new knowledge helps to understand how the structural plate breaks and forms a new boundary.

Tectonic plates are huge rock segments that move continuously relative to one another. They form lithosphere, crust and mantle. The structural plate consists of the ocean and continental crust. The oceanic crust consists of sea and the continental crust consists of land. The structural plate forms a divergent boundary, a deformation boundary, or a convergence boundary when in contact. Volcanoes, rift valleys, mountains and earthquakes are the result of mutual movement of structural plates occurring at structural boundaries. The heat in the mantle causes convective motion of the structural plate. There are large and small structural plates. A total of seven plates covering nearly 95% of the world
