I-geology yeNhlonhlo Yase-Iberia iyathakazelisa kakhulu futhi ayiyeki ukusimangaza. Namuhla sihambela Izintaba zaseGalicia lokho kwaqala ukwakhiwa eminyakeni eyizigidi ezingama-350 edlule. Ngenxa yokushayisana phakathi kwamacwecwe amakhulu amabili ezwekazi elibizwa ngeGondwana neLaurasia, amaphuzu ahlukahlukene wokuthakazelisa komhlaba weGalicia angakhiwa. Sithola amaphuzu amaningana amele izimpawu zomhlaba kusukela sakhiwa.
Sijoyine kule ndatshana kusukela enkathini yePaleozoic kuze kube manje ukwazi izintaba ezihlaba umxhwele zaseGalicia.
Ukugoqwa kweCampodola Leixazós
Lolu hambo siluqale ngezintaba zaseGalicia ngesibaya esamenyezelwa ngonyaka we-2011 njengeSikhumbuzo Semvelo Somhlaba kanye Nendawo Yentshisekelo Yomhlaba Wonke. Kuyisakhiwo se-geological esinqamula kulo lonke elaseGalicia futhi nesiphetho saso esibonakala kakhulu eCourel. Ku-geology, Ukwakheka nezinqubo ezihlobene nezibaya zomhlaba ziyafundwa. Kodwa-ke, awukwazi ukumazi kahle mathupha futhi ubone amafolda. Kulokhu, sithola ukugoqwa kukobukhazikhazi bawo ngendlela yokuthi sikwazi ukubona ukuthi izinqwaba ezimbili zamazwekazi zashayisana kanjani.
Ngemuva kokushayisana kwala mapuleti amabili ezwekazi, kwakheka izwekazi elikhudlwana elaziwa ngePangea. Singasho ukuthi kungumphumela wokuqala obonakalayo we isigaba sokuqala okwakhiwa kuso iGalicia eminyakeni engaphezu kwezigidi ezingama-500 edlule. Ngenxa yalokhu inesihloko esaziwayo, ngoba inentshisekelo ekhethekile emphakathini.
Isiqongo Esingcwele
Lona umphumela wesibili ongabonakala kuyo yonke insimu yesigaba sokuqeqesha seGalicia. Inediphozi enkulu ye-quartz, umhlaba we-granite, njll. Le ngxenye yezintaba zaseGalician yaqanjwa ngenxa yokuhamba kwe amacwecwe e-tectonic lokho kwenzeka ngesikhathi sePaleozoic cishe eminyakeni eyizigidi ezingama-400 edlule.
Le ntaba iqukethe iphuzu elibaluleke kakhulu emlandweni wokuma komhlaba waseGalicia. Yilapho baboshwa khona amapuleti amabili we-tectonic ashayisana futhi akha i-geology eyaziwayo. Ekuqaleni, enyakatho yedayi lapho kutholakala khona i-quartz ephezulu, ibinganweba okwaziwayo njengeLaurasia futhi, ngaseningizimu, iGondwana, okuyiyona ezobeka umngcele ngaphakathi kweGalicia.
I-Granite massif ka-O Pindo
Elinye iphuzu elihlotshaniswa nalokhu kushayisana kwama-tectonic esikhuluma ngakho. Iyabonakala ngisho nasempilweni yamanje futhi ngenxa yayo ungafunda okuningi mayelana nokwedlule. AmaGranites ayengamatshe okuqala ukwakhiwa eGalicia. Lokhu kwenzeka eminyakeni eyizigidi ezingama-300 edlule.
I-morphology yalesi massif ibhekisa emzimbeni womlingo owahlanganiswa enhlabathini engaphansi ngamakhilomitha angaba ngu-20. Kusukela ama-geological agents Njengoba ukuguguleka komhlaba bekusebenza iminyaka eyizigidi ezingama-300, namuhla singabona yonke indawo lapho i- Isikhathi seMesozoic.
ICape Ortegal
ECabo Ortegal sithola amawa amaningi ahambelana nesigaba sesibili lapho kwakhiwa khona iGalicia. Cishe eminyakeni eyizigidi ezingama-200 eyedlule, ekuqaleni kweMesozoic, izwekazi elikhulu elaziwa njengePangea laqala ukuhlukana. Ngenxa yalokho, yayihlanganisa futhi ihlukanisa iNhlonhlo Yase-Iberia. Le nhlangano yiyo eyadala ukwakheka kogu lwaseGalician kusuka enyakatho kuye entshonalanga.
Lawa mawa aziwa njenge-intraplate, ngoba ayengaphakathi kwepuleti elikhudlwana elaziwa ngePangea. Akusilo iwa elenziwe ngenxa yokuguguleka kolwandle eminyakeni edlule. Ngenxa yokuthi zakhiwe ngokuqhekeka kwepuleti elikhulu, zigcinwe kahle kakhulu. Lokhu kungenxa yokuthi ama-geological agents awakwazanga ukwenza isikhathi eside ukudala lokhu kugqoka.
Impophoma ye-O arozaro-Xallas
Ngenye ingxenye yezintaba zaseGalicia lokho lakhiwa eminyakeni eyizigidi eziyi-145 edlule. Imifula eyayigobhoza phezu kwalokho manje okuyiGalicia yayingafinyelela olwandle futhi igelezele kulo. Ukuguguleka komhlaba okudala imifula phakathi naso sonke lesi sikhathi kuyimbangela yokukhululeka kwezigodi ezigelezayo zeGalicia.
Ukuguguleka komfula kunamadwala amelana impela, yize umfula ungeke wakwazi ukukhipha konke ukujula okusezigodini. Icala elibonakala kakhulu esinalo lokuguguleka komfula yilona esilibonayo ezimpophomeni zoMfula iXallas.
Ourense Depression-umthombo womfula iMiño
Elinye igugu esilibonayo futhi elisinikeza imininingwane eminingi mayelana nokwakheka kweGalicia. Silindele vele kuze kube yiminyaka eyi-2,5 million yeminyaka. Uhla lonke lwezintaba zaseCantabrian ludlulela eningizimu luze lufike eCelanova. Ngesikhathi sokuvakasha kwayo, ilandela uhlelo lwamathisele we-tectonic abelokhu esebenza kusukela ukuphela kwe I-Cenozoic. Yilawo wonke amathuna ajwayelekile abonisa ukudangala kwe-Ourense lapho umfula iMiño uzalwa khona,
Izingxenye zoxhumano lomfula olwaluhamba kuyo yonke le ndawo lwaphambukiswa ukucindezeleka. Yize umfula iMiño ungowokugcina kunayo yonke imifula yaseGalician, Yiyona ehamba kakhulu futhi, ngakho-ke, ebaluleke kakhulu.
Ukwakhiwa kwezizalo zemifula yaseGalician nezinqubo zezindunduma
Ukwakheka kwe-Dune nakho kwenzeke ezintabeni zaseGalicia. Imiphumela kusimo sezulu kanye nokuguqulwa kwaso okwalandela ngesikhathi seQuaternary kwakubangela izindawo ezithile ezisobala ogwini lolwandle. Ngakolunye uhlangothi, bekunezinqubo ezihlangana phakathi kwezinhlanga ezibangelwa yisimo sezulu esifudumele nezinye izigaba zeqhwa ezinesimo sezulu esibandayo. Ngesikhathi esifudumele, iqhwa lalincibilika futhi nolwandle lwakhuphuka. Lokhu kudale ukuthi amanzi olwandle angene phakathi nezwekazi. Yile ndlela okwakhiwa ngayo imifula njengoba sazi namuhla. Lonke ulwandle lwangena kwaze kwaba sekugcineni kwemifula, lwagcwala yonke into.
Ukwakhiwa kwezindunduma kufana nezinqubo zesimo sezulu esibandayo. Ngalesi sikhathi, isimo sezulu sasibanda, ngakho ulwandle lwalungaphansi. Kwahlala-ke ipulatifomu yasogwini ivezwe kakhulu futhi yambozwa ngesihlabathi ngenxa yokuguguleka.
Ngiyethemba ukuthi ngalolu lwazi ungafunda kabanzi nge-geology yezintaba zaseGalicia.
