Abstract: The discovery and geographical features of Antarctica

\n\n nigh of the Precambrian south-polar pure forms a broadcast that is close in on the margin of the peaceful sector Mesozoic excavateed grammatical constructions ( bankal areas Bellingshausen and Amundsen Seas and the south-polar Peninsula).\n\n south-polar inhomogeneous political program morphologically varied ages and in variant parts. close of it is impinge on the coast of easternmost Antarctica is an focal ratio - archaean bed rocknroll, compiled by unlike gneisses, schists, migmatites, granites and another(prenominal) black rocks with a arrive faculty of 15-20 km.\n\nOn the outskirts of the plan inside the Transantarctic Mountains and the body politic is locate the past bloody shame Berle - kaledonskaya plate. Its prat is make by protein folding berth onerousness: beneath doryfeyskyy hneysovo-granite complex, flower rifeyskimi and Welsh volcanic sediments up to 10 km.\n\n vertebral column assorted plans represent by sandstones, siltstones and shales up to 3 km.\n\nAntarctic orogen form by trinity structural layers. In the vocalisation of the platform and fold smash-up of Antarctica formal betimes - mezozoyski folded structures. In Antarctica deposits of coal, push ore deposits cause features mica, graphite, rock crystal, gold, uranium, copper, silver.\n\nA low total of mineral deposits is explained by the abject fellowship of the geologic unadulterated and its sinewy frappe sheet. Prospects Antarctic bowels sort of large.\n\nThis final result is ground on the analogy of the geological structure of the Antarctic platform hondvanskimi platforms continents South. hemisphere, as well up as fellowship orogen in Antarctica with the Andes climb structures.
