KuBaltic Shield: landform, tectonic marongerwo uye zvicherwa

Baltic nhoo akadana mukuru dobaykalskaya simba akapeta munharaunda Alps. Panguva yose yokuvapo unomutswa zvishoma nezvishoma pamusoro pegungwa. KuBaltic Shield asingatani rikukurwe. Anoratidza yakadzika mapazi ari girenayiti-gneiss bhanhire pasi goko.

nhoo Location

Wandisa inobudisa fungidziro wokuchamhembe-dzokumadokero expanses vokuMabvazuva European papuratifomu. Navo parutivi mamiriro Caledonia-dzekuma Scandinavia. Ivo vakaswedera pamusoro crystalline nematombo akapeta nzvimbo.

Yakarwiwa panzvimbo inonzi Karelia, Finland, Sweden, kuti Kola Peninsula anofukidza kuBaltic Shield. Chikuru protrusion Anomhanyira Murmansk uye Leningrad nharaunda. Ivo vakatora rinenge rose Air Peninsula.

landforms

Nokupesvedzera glaciations kuumbwa remadziro zvokuyamura. madziva vakawanda nenzwi ichitenderera kumiganhu. Vari achicheka munyika, dzikaumba vakawanda bays uye zvitsuwa. The nechekuchamhembe pleated anosimudza aumba kubva schists yekare uye igneous matombo. The zvivako vauye pamusoro kwose kwose. Ndivo chete mune dzimwe nzvimbo akafukidza simba raincoats Quaternary sediments.

Crystalline kuBaltic Shield haina yakafukidzwa nemvura gungwa Lower Paleozoic yaitonga, nokuti yaiva pasi kuparadzwa. Crumpled mipendero vane kunzwisisa maumbirwo akawana kunyanyisa kwoukukutu uye brittleness. Naizvozvo, kana iri goko iri dzaisiyana, kwakaonekwa makatsemuka, inova nzvimbo kutsemuka. Species kuparara, pova hombe zvinogumbura.

Relief yeRussian Platform

Mazitombo echando, zvishoma nezvishoma mumatope pasi mawere ari Air makomo, kuparadza crystalline bhesimendi matombo anoputsa kutsungirira kupfuura Russian papuratifomu. Stuffed mamiriro, kuunganidza, akaumba moraine.

Kubvunda rechando refu nguva nesimba rire kuBaltic Shield. Form yokusunungurwa pamusoro Musara vakatodzidza accumulative chimiro. The akapeta nzvimbo akazviratidza eskers, drumlins, uye zvichingodaro.

Relief Karelo- misa Kola

Kola Peninsula uye yakarwiwa panzvimbo inonzi Karelia akaumbwa pamatombo, anenge asiri razmyvam. Ndivo Eriya aitombotyawo mvura. Kunyange zvazvo nzizi vemo kunoratidzwa zhinji eko, vakanga vasingakwanisi kuva mumipata. Riverbeds yakazara pano Mangondo nemapopoma. Water mafashamo dzakawanda dzegirini akaumba pamusoro vachisimudza mugungwa akapeta.

Kunyevenutswa chikamu ichi asiri yunifomu bhodhi. Musi Kola Peninsula kunosvika kumadokero gomo bhandi, izvo anoda pakati huru mwoyo. Pamusoro Khibiny tundras uye Lavozerskimi kubhururuka chemhando gomo twi.

The kumabvazuva Peninsula anotora slaboholmistoe rwenze anorembera pamusoro pemvura yegungwa Bagretsovogo. chikomo diki Izvi merges pamwe nebani azviveza Sea White.

Munharaunda yakarwiwa panzvimbo inonzi Karelia ane maitiro nzvimbo Baltic Shield. Landform akapeta nzvimbo panguva ino denutatsionno-tectonic. goko The Earth riri chaizvo wakatsemuka. Dzegirini, ayo akapararira anezvimiti uye madhamu vari yaiteverwa ne matombo anooneka zvikuru nemichinjiziri uye zvikomo.

Pedyo Finland akatambanudza chikomo Maanselkya. pamusoro waro zvikuru dissected. On the akapeta vachisimudza kwose rakakurumbira glacial nomunzvimbo dzine, accumulative uye ekzaratsionnyh configurations. KuBaltic Shield iri Dziine misoro emakwayi, makuru boulders, eskers, moraine anooneka zvikuru nemichinjiziri uye mumipata.

Geological mamiriro

Akapeta waigona geosegmenta akakamurwa nhatu: Karelian-Kola, Svecofennian uye Sweco-Norwegian. In Russia dzinenge zvachose ndiye Karelian-Kola nharaunda uye kumaodzanyemba-okumabvazuva nendima Svecofennian misa.

The Geological nemamiriro Karelian-Kola chidimbu haina kufanana munharaunda muGungwa White, inozivikanwa zvikuru kukura Proterozoic idzodzo. Izvi imhaka matatu chinokonzera: Kuva akasiyana kutigumbura Geosyncline, nhoroondo kukura zvakasiyana Kuparara udzamu zvidimbu. Karelo- Kola chidimbu kusiyana Belomorian nechigumbuso hwakasimba kusiyiwa.

Vanhuwo chepfungwa tectonic nemamiriro zvikamu iri kuchamhembe-yokumadokero tatamuka nharaunda. Zvivako inoumbwa matombo uye pazvirugu, chete neapo vanobvuma kusatsauka Meridian kana latitudinal mirayiridzo.

Zvivako uye pazvirugu, akaputsa sezvinoita dzinoshandisa kumaodzanyemba kwakadziva kumabvazuva, wekuita kuchamhembe. Zvicherwa majini chokuita yekare igneous uye metamorphic matombo akaumba Baltic Shield. Tectonic mamiriro achitevedza miganhu Regional zvikamu akapa mitswe yakadzika.

Aidzorwa rinotsemuka ndiyo nzvimbo Precambrian intrusive zvivako uye dzavo metallogeny. Kunobereka dzikarongwa zvikamu amutambanudzira iri kuchamhembe-kumadokero. Ndivo akaererana nevakawanda nzvimbo panowanikwa Precambrian Geological hurongwa.

dhipoziti

Rich deposits of kuBaltic Shield. Mineral zvinhu anoparadzirwa pamusoro bhandi. Pfungwa iri accented pamusoro matatu. Mune Flower mapazi ari Kola Peninsula yakavanda mhangura-nickel ores. Achishingaira akadzidza Vetrenyi Belt mamiriro zvichienderana Karelian pasi uye Arkhangel'skii nyika. Muna Karelian-Kola chidimbu anonakidza nguva pamwe ferruginous quartzites, schists, kyanite uye pegmatites siyana. Sumbu yokucheka mapuranga akagadzirisa lithologic uye stratigraphic uye STRUCTURAL zvinhu tectonic.
