Baltic Shield: elimi, isakhiwo ziitectonic plates kunye neeminerali

ikhaka lweBaltic ebizwa dobaykalskaya enamandla kummandla esongiweyo mdala Alps. Ngalo lonke ixesha lokubakho ukuba liyanda ngaphezu komphakamo wolwandle. Baltic Shield othambekele kukhukuliseko. Aveza izowuni nzulu ibhanti lenyengane-gneiss of kolu qweqwe lomhlaba.

isihlangu Indawo

Kuku inyathela ezayo emantla-ntshona babeziindleko kweqonga European East. Nabo ecaleni isakhiwo kwicala Caledonia-yaseScandinavia. Bona phambili ematyeni crystalline elisongiweyo ndawo.

Karelia, eFinland, eSweden, i Kola Peninsula ubandakanya kwiBaltic Shield. Le Buze enkulu isebenza kummandla Murmansk naseLeningrad. Anazo phantse lonke laseScandinavia Peninsula.

zomhlaba

Phantsi yempembelelo glaciations kwakhiwa uncedo panel. emachibini abaninzi yabakho ngokubhijela mida. Baya ukunciphisa ezweni, ukwakha iindawo ezininzi iziqithi. Inxalenye esemntla okukunyusa elincane wabumba schists yamandulo igneous. Izithinteli beza kumphezulu yonke indawo. Bathi kuphela kwezinye iindawo agubungele njengeebhatyi ibuthathaka neetyuwa koqeqesho.

Crystalline Baltic Shield kungakhankanywanga phantsi kwamanzi olwandle ne Lower Paleozoic xesha, ngenxa apho phantsi kwintshabalalo. ezibayeni Ndayishwabanisa kunye nesakhiwo esimbaxa olufunyenwe ngokuba lukhuni ngokugqithiseleyo kunye brittleness. Ngoko ke, xa kwesikhoko tshintshwa, kwabonakala kuvela iintanda, uba indawo zaphuka. Iintlobo uyachitheka, ukwakha iibhloko omkhulu.

Uncedo lo Platform Russian

Ezihambayo, beya phantsi kwamaxandeka zeentaba yaseScandinavia, batshabalalisa namawa ongaphantsi crystalline ozithukululeyo ukunyamezela ngaphaya platform Russian. isakhiwo eyimitha, baba, ukusekwa gquma.

Ukunyibilika ixesha glacier elide ngamandla eyayihamba kwiBaltic Shield. Ngohlobo oluthile loncedo kwi Inqwanqwa abazifumene imilo numbers. Le ndawo elisongiweyo wabonakala eskers, drumlins, njalo-njalo.

Uncedo Karelo- block Kola

Kola Peninsula kunye Karelia iqanjwa ematyeni, phantse non-razmyvam. Yokuba ingenwe emanzini. Nangona imilambo zasekuhlaleni luphawulwa kwamanzi amaninzi, abazange bakwazi ukuphuhlisa iintlambo. Imifula yokuhamba apha ohamba neengxangxasi. nezikhukhula Water misinga amaninzi kwakheka kwi okukunyusa echibini esongiweyo.

Isiqabu kule nxalenye lebhodi non-uniform. On the Kola Peninsula zinabela ibhanti ezintabeni ngasentshonalanga, leyo yakhona ukuba ukudakumba enkulu. Kule Khibiny namathafa angenamithi kunye Lavozerskimi inokubhabha ezi ziphakamileyo iintaba.

Icala mpuma lizwe kuthatha slaboholmistoe isisitheliso ihewu phezu kwamanzi olwandle Bagretsovogo. Le induli encinci zidibana kunye esezantsi Wayakha Sea White.

Xa babekwingingqi Karelia na indawo uphawu Baltic Shield. Elimi esongiweyo ndawo kule ngongoma denutatsionno-ziitectonic plates. kuqweqwe lomhlaba ingcole aqhekekileyo. Misinga, ezo imigxobhozo esichitha-chithwe kunye amachibi Zinokuxutywa emile lengxondorha, neenduli.

Sondela Finland Wasolula hill Maanselkya. kumphezulu wayo dissected kakhulu. On the siphindwe uphakamisa sisimo yagubha jikelele ntlango glacial, numbers kunye ekzaratsionnyh. KwiBaltic Shield ligcwele neentloko zeegusha, ukuze kuvuleke ezinkulu, eskers, nakummango gquma neentlambo.

phawu neznye

geosegmenta liphakamisa esongiweyo izigaba ezintathu: i Karelian-Kola, Svecofennian kunye Sweco-Norwegian. In Russia iphantse ngokupheleleyo ummandla Karelian-Kola kunye nakwimimandla kumzantsi-mpuma block Svecofennian.

Isakhiwo zejoloji Karelian-Kola ingxenye ayinjalo kummandla kuLwandle White, esibonakala uphuhliso olubanzi Proterozoic namabandla. Oku kungenxa yokuba izinto ezintathu: ngoweqela iibhloko ezahlukeneyo Geosyncline, uphuhliso yembali ezahlukeneyo izilayi ukhukuliseko ubunzulu. Karelo- Kola ingxenye ngokungafaniyo ibloko Belomorian lishiyiwe ngakumbi.

Olona phawu oqhelekileyo isakhiwo ziitectonic plates seziqingatha na umgama kumntla-ntshona kwimimandla. Izakhiwo zenziwe ngamatye nezibaya, ukuvumela manqaphanqapha ngokwabo ukuba ziphambuke ulwalathiso okuyi okanye latitudinal.

Izakhiwo kunye nezibaya, waziqhekeza kunyuka fan kwi mpuma, idibane emntla. Nezithako ezinxulumene izakhi kunye igneous yamandulo nemetamorphic wabumba Baltic Shield. isakhiwo ziitectonic plates ngaphaya kwemida amacandelo emimandla thaca kuziphuko zendalo ezinzulu.

Phantsi kolawulo nobanda na indawo kwizakhiwo Precambrian izifaka kunye metallogeny zabo. Kubangela zihlelwe zayimimandla, esukela emntla-ntshona. Bona ngaxeshanye kwiindawo eziqhelekileyo ingenzeka kwezakhiwo Precambrian zejoloji.

idiphozithi

iidipozithi Rich ye kwiBaltic Shield. imithombo yezimbiwa zisasazwa ebhantini. ingqalelo oluthile uzakuwushiya ungajongwangwa ngexeshana abathathu kubo. In the Flower izowuni i Kola Peninsula ores ezifihlakeleyo ubhedu-nickel. Ngenkuthalo wafunda isakhiwo Vetrenyi Belt ngokuvumelana Karelian ngobuso kunye namazwe Arkhangel'skii. In the Karelian-Kola ingxenye amaxesha umdla quartzites ferruginous, schists, kyanite kunye pegmatites ezahlukeneyo. amaplanga Cluster zilungiswe lithologic kwaye stratigraphic kunye nemiba zezakhiwo ziitectonic plates.
