Baltic Chikopa: landform, tectonic kapangidwe ndi mchere

Baltic chishango wotchedwa wamkulu dobaykalskaya wamphamvu apangidwe m'dera la Alps. Kuyambira nthawi ya kukhalapo izo limatuluka likunena pamwamba pa nyanja. Baltic Chikopa sachedwa kukokoloka. Kufufuza woyendera nthambi kwambiri lamba lubwe-gneiss ya matanthwe a pansi padziko.

chishango Location

Chachikulu likuthandiza ziyerekezo kwa expanses kumpoto chakumadzulo kwa nsanja East European. Ndi iwo mbali ndi mbali dongosolo Caledonia-Scandinavia. Asilikaliwo crystalline miyala apangidwe m'deralo.

Karelia, Finland, Sweden, ndi Kola Peninsula chimakwirira Baltic Chishango. The protrusion lalikulu amayendera Murmansk ndi Leningrad dera. Iwo wotanganidwa pafupifupi buku lonse Scandinavia Peninsula.

landforms

Mothandizidwa glaciations anapanga mpumulo gululi. maiwe ambiri anapangidwa ndi kumulowetsa m'malire. Iwo kudula mu dziko, kupanga Magombe ambiri ndi zilumba. Mbali ya kumpoto zochotsa zilimba zake anapangidwa kuchokera schists wakale ndi miyala igneous. nyumba anabwera pamwamba kulikonse. Zangokhala m'madera ena kuphimba wofooka raincoats Quaternary m'dambo.

Tinthu Baltic Chikopa si anaphimba ndi madzi nyanja ndi wotsika Paleozoic nyengo, chifukwa chimene chinaperekedwa ku chiwonongeko. Ankangodzigwera makutu ndi dongosolo zovuta wabweza kuuma zimabwezera brittleness. Choncho, pamene kutumphuka ndi zosiyanasiyana, pamenepo adawonekera ming'alu, amasanduka malo a wovulala. Species likuphwasuka, kupanga midadada yaikulu.

Mpumulo wa nsanja Russian

Oundana, kutsetsereka pansi otsetsereka a m'mapiri a ku Scandinavia, kuononga crystalline chapansi miyala anamasuka kupirira kupitirira nsanja Russian. Modzaza dongosolo, wambirimbiri, anapanga moraine.

Kusungunuka nthawi glacier yaitali mwamphamvu ndinawapanikiza ndi Baltic Chishango. Fomu mpumulo pa Chigawo anapeza mawonekedwe accumulative. M'dera apangidwe anaonekera eskers, drumlins, ndi zina zotero.

Relief Karelo- chipika Kola

Kola Peninsula ndi Karelia ndi lopangidwa ndi miyala, pafupifupi sanali razmyvam. Iwo Anachita madzi. Ngakhale mitsinje m'dera amakhala ndi runoff zambiri, sanathe kukhala ndi zigwa. Mitsinje wokhala pano mathithi ndi mathithi. Madzi osefukira matendawa, ambiri anapanga pa apangidwe zochotsa nyanja.

Mpumulo mu gawo ili la thabwa si yunifolomu. Pa Kola Peninsula akutambasula kumadzulo phiri lamba, amene ranges pakati ndi maganizo lalikulu. Pa Khibiny tundras ndi Lavozerskimi kuuluka apamwamba phiri nsonga.

Kum'mawa kwa chilumba amatenga slaboholmistoe yachonde ukulendewera pa madzi a nyanja Bagretsovogo. Izi phiri laling'ono merges ndi lowland lathuli White Sea.

M'chigawo cha Karelia ali ndi malo khalidwe Baltic Chishango. Landform apangidwe m'dera pa mfundo iyi denutatsionno-tectonic. kutumphuka dziko lapansi kwambiri losweka. Matendawa,, amene anamwazikana zithaphwi ndi nyanja ndi interspersed ndi zitunda miyala ndi mapiri.

Pafupi Finland anatambasula phiri Maanselkya. pamwamba yake kwambiri kuligaŵa. Pa apangidwe kukweza masanjidwe konsekonse titchuke glacial mtunda, accumulative ndi ekzaratsionnyh. The Baltic Chikopa ali lili ndi mitu nkhosa, boulders lalikulu, eskers, moraine zitunda ndi zigwa.

Geological mbali

Apangidwe zochotsa geosegmenta ogaŵikana atatu: Karelian-Kola, Svecofennian ndi Sweco-Norway. Mu Russia pafupi kwathunthu ndi dera Karelian-Kola ndi madera kum'mwera kum'mawa Svecofennian chipika.

Kapangidwe miyala ya gawo Karelian-Kola si monga m'dera White Nyanja, yodziwika ndi chitukuko yaikulu Proterozoic formations. Ichi ndi chifukwa cha zinthu zitatu: yoperekedwa kwa midadada osiyana Geosyncline, chitukuko mbiri yosiyanasiyana kukokoloka kuya magawo. Karelo- Kola gawo mosiyana chipika Belomorian mphamvu zasiyidwa.

Mbali wamba kapangidwe tectonic a zigawo ndi kumpoto-kumadzulo Tambasula pamadera. Maofesi popangidwa ndi miyala ndi makutu, apo amalola panjira meridian kapena latitudinal malangizo.

Maofesi ndi makutu, anaphwanya ngati fani ndi kum'mwera chakum'mawa, converge kumpoto chakumadzulo kwa. Mchere chibadwa zogwirizana ndi igneous akale ndi miyala metamorphic anapanga Baltic Chishango. Tectonic dongosolo pamodzi malire a zigawo dera anapereka fractures kwambiri.

Pansi pa ulamuliro wa amang'amba ndi malo a Precambrian maofesi intrusive ndi metallogeny awo. Mitundu yagawidwa m'zigawo, anakafika kumpoto chakumadzulo. Iwo kufanana kwa malo wamba zosayembekezereka wa nyumba Precambrian miyala.

gawo

Olemera madipoziti ya Baltic Chishango. chuma mchere amafalitsidwa pa lamba. chidwi ndi accented pa atatu a iwo. Mu Flower zone wa Kola Peninsula chinabisidwa mkuwa faifi tambala ores. Mwakhama anaphunzira Vetrenyi m'Galimoto dongosolo malinga Karelian Kudzilambatitsa ndi minda Arkhangel'skii. Mu gawo Karelian-Kola nthawi chidwi ndi quartzites ferruginous, schists, kyanite ndi pegmatites zosiyanasiyana. Limodzi macheka kusintha lithologic ndi stratigraphic ndi mbali structural tectonic.
