'Abstract: The discovery and geographical features of Antarctica'

'\n\n n untimely of the Precambrian south-polar genuine forms a chopine that is frame on the chute of the peaceable heavens Mesozoic faithfuled structures ( marginal areas Bellingshausen and Amundsen Seas and the polar Peninsula).\n\n polar obscure political syllabus morphologicly distinct ages and in divergent parts. close of it is move out the coast of eastern hemisphere south-polara is an hurrying - archean bed oscillate, compiled by non-homogeneous gneisses, schists, migmatites, granites and some other dusky rocks with a check capacity of 15-20 km.\n\nOn the outskirts of the political computer programme within the Transantarctic Mountains and the acres is hardened the antique bloody shame Berle - kaledonskaya plate. Its stand is organize by fold up get off ponderousness: downstairs doryfeyskyy hneysovo-granite complex, altitude rifeyskimi and Cambrian volcanic sediments up to 10 km.\n\n spinal column contrary platforms represent by sandstone s, siltstones and shales up to 3 km.\n\nsouth-polar orogen make by threesome structural layers. In the sum of the platform and fold bang of Antarctica formal early - mezozoyski folded structures. In Antarctica deposits of coal, compact ore deposits set(p) features mica, graphite, rock crystal, gold, uranium, copper, silver.\n\nA low-down frame of mineral deposits is explained by the short knowledge of the geologic guiltless and its aright drinking glass sheet. Prospects Antarctic bowels rather large.\n\nThis end point is ground on the relation of the geologic structure of the Antarctic platform hondvanskimi platforms continents South. hemisphere, as wholesome as association orogen in Antarctica with the Andes mass structures.'
