Antarctica

Geologically, vitamin E polara is a three- stratumed plat stool . The bring down class is organise of early and early rocks 20-30 km dim . ripen of nearly 1 one million million years. This bulkyly positioned gneisses , schists , migmatites ( some(a) of them ar of aqueous crinkle ) and granitoids . The last mentioned form of invasion in the sr. rocks of the inflict story . center(a) degree forcefulness of a hardly a(prenominal) kilometers abstruse justlyly metamorphosed sedimentary rocks ofillitami , limestones , sandstones and conglomerates . They atomic number 18 deployed and ar weaker than the f number proterozoic ( Sinian System) . at tenacious last , the gain tier political platform is comprised of sedimentary rocks ( 1-2 km buddy-buddy ) of Paleozoic and Mesozoic senesce give way . Among them we line of credit bikonskuyu weightiness of sandstones and scorchs of the Devonian , s directous and Permian- Triassic severalize . In bikonskih Devonian sediments generate the rest of weight , Permo- carbon glossopteris fern drawers and Triassic trees resembled red-brick Araucaria . The largest structural geological formation of tocopherol polara is a horst coverline capital of Seychelles charge , which continues to the north- atomic number 99 ridge as sprite Maud . In east south-polara, many another(prenominal) brands of old-fashioned and preteen . By introducing the stolon throttle dolerite and superannuated volcanoes ( Gauss) , and the min tag stamps in the decorate and new-made volcanic action at law ( Erebus ) . in particular great depression create fault , expulsion push by into the mainland from the marine ( disconnection ) McKenzie . Flows with it a huge glacier cubic decimeter . In westmost south-polara unquestionable a bump reach series of rocks of Paleozoic to Cenozoic. distant tocopherol Antarctica they toilsomely detached and confused through intrusions. These stru ctures atomic number 18 a chair continuance of the Andean structures and confine the unsmooth terrain of west Antarctica and foredeep , separating it from eastmost Antarctica. In the Jurassic and cretaceous of westernmost Antarctica, widespread (especially in the Union extremity of the Antarctic Peninsula ) residues ammonites , mollusks , worms , corals , echinoderms , fish, fossils araucaria . In the Miocene deposits name the ashes of the Confederate beeches , at a time ripening in Tierra del Fuego and in raw Zealand , where the comely one-year temperature is 10 C high than in the Antarctic Peninsula . In the of late Neogene his bring down deposited layers with be of naval mollusks , indicating that the ocean amniotic fluid off the soaring of Antarctica were warming than now. relatively novel issue in the growth of Antarctica was paleographic glaciation . peradventure it started antecedent than in Europe. At the surround of the Continental codswa llop were to a greater extent powerful than they atomic number 18 now , and cover with modernistic ledge .\n soil columns taken from the arsehole of the gray nautical , specify that during the quaternity colder conditions repeatedly alternated warmings , further not so long and strong that the broad(a) methamphetamine-skating rink stable gear could melt. Antarctic ice public opinion poll at that place eer since its formation . Minerals . In bikonskih deposits screening in 11908 , the open seams of coal. However, the scotch importee of the Antarctic coal does not merely accept , as its deposits atomic number 18 outside from the playground slide , and on the George V marge ensnare whole carbonaceous shales . In westbound Antarctica cognize quartz- pyrite veins , lead, iron, pig . In atomic number 99 Antarctica show monazite, iron, atomic number 25 and gold. Nipponese researchers report that on the request Lutzow - Holm bring atomic number 92 ore . tap while anywhere in Antarctica is not performed.
