Xilligii Mesozoic

Xilligii Mesozoic waxaa loo tixgeliyaa sida marxalad KMG ah ee horumarinta caalamka. Haseyeeshee qaar waxa ay ugu yeedhaan "nafleyda iyo dhulka ee qarniyadii dhexe."

Xilligii Mesozoic bilaabay dhamaadkii Variscan (Variscan) ee geedi socodka buurta u-dhiska, oo dhammaadkeedu wuxuu - iyadoo bilowgii Alpine laabi (kacaanka ee la soo dhaafay tectonic waaweyn).

In Hemisphere koonfurta, waxaa dhamaaday kala ah qaaradda hore ee Gondwana. Guud ahaan, nolosha xilligii Mesozoic lagu gartaa deji qaraabo. geedi socodka dhismaha buurta ahaayeen dhif iyo muddo kooban ah.

Mesozoic Era ayaa socday ku dhowaad 160 million. Years.

Laga soo bilaabo dhibic noolaha of view, Zaman this waa waqti kala guur ah oo ka heer hoose ah, foomamka jir cusub ayaa in ka badan horumar. dunida oo wakhtigaas ahaa kale oo badan oo kala duwan ka badan in Paleozoic ah, iyo dhirta iyo ugaarta ayaa si weyn u la casriyeeyay.

Era Mesozoic. muddooyinka

Waxaa jira saddex marxaladood ee Zaman this.

Midkii kowaad wuxuu u - Triassic - si la odhan jiray sababtoo ah xaqiiqda ah in lacag dhigaal ah oo uu ka mid ah saddex adag noocyada kala duwan ku qoran. Kuwaas waxaa ka mid neyper - calcareous sare - sandstone qaaradda dhexdhexaad - hoose. Inta badan caadiga ah waa qaaradda dhagax weyn ciid-dhoobo (oo inta badan leh lenses carbon), Shale, nuuradda badda, gypsum, cusbada, haro badda anhydrides.

xarunta Triassic waxay ahayd qaaradda koonfurta (Gondwana) la qaarada waqooyiga (Laurasia). Oo ay la socdaan, kuwaas oo isbeddel ah ee qaybinta dhismaha buurta, formation of meelaha cusub ee Kobenhagen Barriga iyo Badda,, meel qaaday arrin degdeg ah iyo warsiinta dhirta iyo ugaarta. Si kastaba ha ahaatee, keliya ah noocyada yar ayaa ka soo dhaqaaqay Paleozoic si Mesozoic. Sida baadhayaashu, arrimahaasi waxay yihiin natiijada masiibooyinka oo baaxad weyn oo ka dhacay on soohdinta reer xilliyo.

marxaladda soo socota, oo ay ku jiraan xilligii Mesozoic - Jacka ah. Waxaa bilaabay 200 oo dhammaadkeedu wuxuu ku saabsan 145,5 milyan. Years ka hor. muddo Jacka noqday mid ka mid ah muddooyinka ugu caansan ee horumarinta caalamka.

Wakhtigan, ugu ballaaran ka mid ah dhirta ku helay gymnosperms iyo ferns isticmaalo. Waxaa la malaysan in xaaladaha deegaanka ahaayeen mid ah xaaladaha muddada Carboniferous ah, si formation char ballaaran xusay. Jiraye ee Permian ah, Triassic bilaabay inuu crack nidaamka qaarada weyn sii waday in ay suuska. Hawlgalkani waxa uu leeyahay saamayn wayn ku yeelan hadda badda, roobab, cimilada iyo shuruudaha jiritaanka noolaha guud ahaan.

Muddada Jacka waxaa loo arkaa "wakhtiga xamaarato." Dalka oo la degganaa by dinosaurs. In badaha ku noolaa plesiosaurs iyo ichthyosaurs, hawada - pterosaurs ah. Ka mid ah dinosaurs ahaa ayaa bilaabay inay sameeyaan noocyada Rafaa. Oo ay la socoto this, waxaa jiray pterodaktili yar carnivorous. Marka ay dhamaato muddada Jacka, waxay bilaabeen raasamaal of layers israac awood nuuradda - nuurad lahayn. Sidaas darteed, marxalad cusub.

Bilowgii muddada Cretaceous waxa lagu gartaa qaar ka mid ah dhacdooyinka ugu waaweyn ee dhismaha dunida organic. Wakhtigan waxay bilaabeen inay u muuqdaan ugu horeeyay ee dhirta ubax, fossils kuwaas oo lagu soo bandhigay in caleemo qoryo iyo dhagaxyo dhexdooda, sii kordhaya, iyo maanta (tusaale ahaan, Elm, geedkii ku, safsaf, Maple). dubato ee muddada Cretaceous waa la mid ah ka mid ah in uu u qoondeeyey in muddada Jacka.

dhamaadka marxaladda this waxaa lagu gartaa orogeny daran (dhismaha buurta) ee Bariga Asia, Waqooyiga iyo Koonfurta America. dhagaxyadii ku aasan ayaa ku ururtay in geosyncline Andean inta lagu guda jiro muddo dhawr, is dulfuulan oo crumpled galay laalaabka. Sayidka sameeyay geedka kokaha.

dhaqdhaqaaqa Kobenhagen ayaa kor u kacay ee gobolo badan oo caalamka. Qaybta dhan koonfureed ee Jasiiradda Indian qariyeen dhagax dab (sidaas sameeyay bannaanka weyn "Dean"). Dhamaadka xilligii Mesozoic on dhammaan qaaradaha ahaayeen uplift weyn.
