Paratiki Shield: hangawhenua, hanganga nekeneke me ngā kohuke

whakangungu rakau Paratiki huaina te dobaykalskaya rohe kaha matamua takai o nga māeroero. Puta noa i te wā o te oraraa e whakatika reira āta runga ake te taumata moana. Paratiki Shield e pängia ana ki te horo. heheu mai ratou i te rohe hohonu i roto i te whitiki ofa'i-te kāhuarau kanapa o kirinuku o te whenua.

Wāhi whakangungu rakau

Nui hopu te ngä o te whanuitanga raki-hauauru o te tūāpapa Te Tai Rāwhiti Pākehā. Ki a ratou taha i hanganga taha Caledonia-Scandinavie. i whakanuia ratou i runga i toka, tioata takai rohe.

Ko te wahi raki o te aranga ki konumihia i hanga i schists tawhito me toka ngiha. haere mai nga hanganga ki te mata nga wahi katoa. Ko ratou anake i roto i te tahi mau wahi hipokina raincoats ngoikore parataiao Quaternary.

e kore te tioata Paratiki Shield taupokina e te wai moana ki Lower Paleozoic era, no te mea o nei i waiho i raro ki te whakangaromanga. Manusinusi taiepa ki te hanganga matatini riro pakeke nui, me te brittleness. Na reira, ka te kirinuku e rerekē, i reira puta kapiti, riro te wahi o te whati. Momo taka motu, hanga poraka nui.

Sotaiete o te Pūhara Russian

Kōpaka, retireti iho nga titahatanga o nga maunga Scandinavian, whakangaro i te kamaka basement tioata tangoro mau tua atu tūāpapa Russian. hanganga puru, piki, i hanga moraine.

Rewa wa awa kōpaka roa kaha i ui ai te Baltic Shield. Puka o te te tauturu whiwhi i runga i te papa hanga Whakaemiemi. puta te rohe takai eskers, drumlins, a na i runga i.

Katia ki Finland totoro pukepuke Maanselkya. Kei te tino dissected tōna mata. I runga i te takai ara hurinoa whakanui whenua glacial, Whakaemiemi me ekzaratsionnyh whirihoranga. mararatia te Paratiki Shield te ki upoko hipi a, toka nui, eskers, tupuke moraine me awaawa.

āhuatanga arowhenua

geosegmenta toronga takai wehea ki toru: te Karelian-kola, Svecofennian me Sweco-Norwegian. I roto i Russia tata katoa ko te rohe Karelian-kola me tuhaa fenua tonga-rawhiti poraka Svecofennian.

e kore te mea rite i roto i te rohe Moana White te hanganga arowhenua o te wāhanga Karelian-kola, āhuatanga e te whanaketanga whānui Proterozoic ngā. he tika ki te toru take tenei: no ki poraka rerekē Geosyncline, te whanaketanga o mua o rerekē poro hohonu horo. Karelo- kola wāhanga pērā poraka Belomorian kaha mahue.

Ko te āhuatanga noa o te hanganga nekeneke o te wāhanga kei roto i te totoro ki te raki-hauauru o te wāhi. Complexes i hanga e te toka, me taiepa, wā anake tukua ki a ratou ano afe aronga afaraa latitudinal ranei.

Complexes me taiepa, whawhati ake rite te powhiriwhiri ki te tonga, ūngutungutu i te raki. Kohuke ira hono ki te ngiha tawhito me toka kāhuarau i hanga Paratiki Shield. hanganga nekeneke haere te rohe o wāhanga rohe aroaro piere hohonu.

I raro i te mana o vaevae ko te wāhi o te complexes urutomo Precambrian me ratou metallogeny. E whakarōpūtia ahu ki rohe, te whakawhānui i te-uru raki. He whakarara ki nga wahi noa o te takanga o ngā hanganga arowhenua Precambrian ratou.
