Graben - waxaa ... Maxaa grabens, iyo sida ay loo sameeyay

In this article ha na baaro su'aasha la xiriirta dhacdo dabeeci ah. Waa maxay dhacaan iyo sida ay u qabanqaabiyey? Sidoo kale, ka hor raadinaya, lacag bixisid si ka duwan ee Graben dareenka - Horst ah.

Waa maxay Graben ee

Graben - Qayb dhula of qolof ah dhulka ee, kaas oo uu sameeyay ay sabab u tahay qalad tectonic oo u taagan ka mid ah qaybaha soo sara kacay.

Grabens inta badan dhaca sabab u ah ciidamada siligga meelaha dhulka sara kiciyey. Under tallaabada ee dagitaan ciidda dhacdaa oo ah qaababka dhagaxa weyn maquufin.

Dhinacyada cidhifyada Graben muuqan Dhuur qaybo, kuwaas oo la aasaasay by raasamaal eyda cusub, kuwaas loo yaqaannaa "baalasheeda Graben ah."

oo dhererkeedu wuxuu gaari kartaa tobanaan dhowr ama boqollaal kiilomitir - in width. The grabens ugu dhawaaqaa oo si fiican u yaqaan waa in East Africa. Waxay ku yaalaan hareeraha harooyinka Tanganyika, Victoria, Nyansa. In Russia, Graben ugu weyn - waa weysada Barguzin, iyo maddiibad ee Lake Baikal.

In Graben nidaamka qoraxda ugu weyn - Valles Marineris, ku yaalaan on Mars. Sababta Education - waxqabad Kobenhagen.

Waa maxay Horst a

Horst - waa Salel on unu block of qolof ah, dhismaha iyadoo ay sabab u dhaqdhaqaaqa tectonic ah.

Qaraabo in ay dusha ka jira saddex nooc oo Horst:

1. Dhiiran - dusha ka badan meesha oo dhan waxaa janjeera hal dhinac.
2. Waslad - waxaa jira stepwise a ku hayay ayaa hoos u.
3. Kali - beddeli unu ama unu dhici on dhinac oo kaliya.

Horst inta badan isu geeyo si ay u abuuraan buuraha dushooda la flat. oo dhererkeedu wuxuu sida caadiga ah waxay gaadhaa boqolaal, iyo width ah - tobanaan kiiloomitir, sarajooggiisuna - dhawr kun oo mitir. Tusaalayaal iska cad cad yihiin kala duwan ee buurta Horst kala duwan buurta Spain Sierra Nevada ee koonfur-galbeed Germany, Forest Black.

Waayo, markii ugu horeysay ee ereyga "Horst" ayaa lagu soo bandhigay in sayniska dhulka ee 1873 by Edward Austria ee Suess. Isagoo ka hadlayay in erayada isaga u gaar ah, Graben - a godkii, Horst - buuraha leh.

khilaaf

Rift - jabka siman toosan weyn ee qolof dhulka ee. Sida caadiga ah, set oo ah Niyadjabka, degan degaanka weyn ee territory.

Waxaa jira laba nooc oo goobaha khilaaf - Oceanic iyo qaaradda.

Natiijadan ayaa waxa ay marka hore ka gaadhista shubay magma soo socda ka bixiyo Dhulka dhulka badda. Magma cadaadis riixo ku adag taarikada lithospheric, sida ka dhashay geedi socodka this waxaa la aasaasay qolof ah dhallinyarada Oceanic.

zones khilaaf Continental loo sameeyay by korinta oo ciiryaamo dusha sare (go'iisii kulul), iyo dhaqdhaqaaqa Kobenhagen dhacdaa khafiifinta iyo iskala of qolof ah qaaradda. ayna duleella u noocan oo kale ah oo keeni karta in formation of Bad cusub. Nidaamka Rift ee Bariga Afrika, kuwaas oo gobolka Canfarta ah, in qaar ka mid ah meelaha la aasaasay qolof ah Oceanic waa yar yahay.

Duleella, taas oo joojisay in horumarka iyo waxa aan la gelin badaha u soo jeestay, wuxuu u yeedhay aulacogens. Sida caadiga ah, meelaha sida sameeyay kayd khayraadka dabiiciga ah. Tusaale ahaan, darbo Devonian Donetsk anigaa iska leh a dhuxusha waaweyn.

Sida caadiga ah isku-dar ah Horst-Graben - aulacogene ah.
