Baikal quav: cov qauv, topography, roob systems, tshwj xeeb yog

Baikal folding originates los ntawm lub sij hawm ntawm orogeny, thiab nws yog nyob rau hauv Siberia. Qhov no lub npe twb qhia geologist Shatsky nyob rau hauv lub thirties ntawm lub xeem caug xyoo nyob rau hauv Honor ntawm tus eponymous lub pas dej, vim hais tias nws yog nyob rau ntawm lub sij hawm, qhov no yog ib feem ntawm lub cheeb tsam tau tsim.

Nyob rau hauv muaj pes tsawg leeg thiab cov yam ntxwv ntawm folding hais tias qhov no tsab xov xwm. Cov ntaub ntawv no yuav pab kom paub ntau ntxiv txog qhov no rau thaj tsam ntawm lub ntiaj chaw.

Tus qauv ntawm folding

Qhov no fold system tsim los ntawm cov merger ntawm ob cheeb tsam - lub Baikal thiab Yenisei. Nws muaj ib tug txheej thiab ib tug puab ib feem, thiab cov ciam teb ntawm lawv protrudes tsam, sau los ntawm lub pas dej rau Mame dej. Baikal cheeb tsam ntawm folding muab faib mus rau hauv sab nraud thiab sab hauv. Cov yav tas muaj xws li cov khoom uas nplua nuj nyob rau hauv ancient pob zeb.

nta

Lub ntsiab feature ntawm lub Baikal yog quav System yog hais tias nws twb tsim los rau ib tug ntev lub sij hawm (tag nrho cov dhau theem Proterozoic), thiab nws tracts muaj nyob rau hauv ntau qhov chaw ntawm lub Urals, Taimyr, Kazakhstan, lub Caucasus, Iran, Tien Shan thiab lwm tus neeg. Nyob rau hauv tas li ntawd, baykality ntau nyob rau hauv lwm qhov chaw ntawm lub ntiaj teb. Piv txwv li, nyob rau hauv Fabkis, Is Nrias teb, North America thiab Australia. Txawm li cas los, nyob rau hauv cov aav yog, es, lawv analogs (Kadoma, minaaskaya, musgravidy). Baikal quav "npog" thiab ib feem ntawm Brazil, nyob rau lub hiav txwv liab ntug dej hiav txwv.

Nyob rau hauv ib qho era ntawm ntau yam platforms baicalensis tectogenetic ces tsim raws li ib tug tshwm sim ntawm cov tectonic furrows, uas tom qab pib sau ib plurality ntawm sedimentary pob zeb. Raws li ib tug tshwm sim ntawm drilling thiab kev tshawb fawb tej hauj lwm nyob rau hauv lub teb ntawm geophysics, cov grooves tau pom nyob rau lwm lub platforms - lub East European thiab Siberian. Txawm nyob rau hauv sab qab teb ntawm lub ntiaj chaw (nyob rau hauv qhov chaw ntawm lub Antarctic), qhov no tsim ib tug folding platform, kev metamorphic thiab sib nqus dab.

lub system

Roob yog hom twg, uas muaj Baikal folding, muaj xws li cov yav qab teb ib feem ntawm Siberia. Cov muaj xws li cov Trans-Baikal thiab cov Baikal cheeb tsam, uas yog ib lub toj Olekma nrog cov plateaus (Vitim, Baikal) thiab uplands (Charskaya, Patom thiab Severobaikalsk). Cov chaw no yuav glaciation. Ntawm no yog situated cov uas tsis muaj roob thiab hav, uas yog nyob rau hauv lub txhaum kab.

Ib tug loj tus naj npawb ntawm cov nplua nuj tej yam ntuj tso kev pab ntawm lub Baikal yog quav. Koom Haum Niam yuav ua li cas tshwj xeeb uas ntau yam deposits yog nyob rau hauv no system (e.g., tooj liab, mercury, kub, tin, zinc, thiab lwm tus). Thiab, raws li lub npe implies, qhov tseem ceeb attraction no yog lub pas dej Baikal, uas muaj ib tug crescent zoo. Nws yog nyob rau hauv lub Baikal roob, ncig rau tag nrho cov sab los ntawm roob ranges. Ua hauj lwm ntawm cov chaw thiab nyiam tourists.

pas dej Baikal

Baikal daim ntau quav tso - tiag tiag ib tug tshwj xeeb qhov chaw. Uas muaj no tsuas muaj ib lub pas dej, hais txog leej twg nws tau hais tias ib tug me ntsis ntau dua. Nws ntev yog ntau tshaj rau puas kilometers, thiab tag nrho cov cheeb tsam npog ib qho chaw peb txhiab square meters. km. Raws li paub ntau, nws yog ib lub deepest nyob rau hauv lub ntiaj teb no. Nyob rau hauv ib co chaw lub qhov tob nce mus txog dua ib mais deb, thiab yog hais tias peb coj tus phem tus nqi, hais txog xya pua. Nws yog ib qho kev txawj ntse uas ntws mus rau hauv lub pas dej muaj ib tug ntau ntawm cov dej ntws (ntau tshaj peb puas), thiab ua raws li tsuas yog ib - lub Angara. ntau tshaj ib nrab los ntawm cov khoom dej ntawm tus dej. Selenga. Nyob rau Baikal muaj ob peb Islands tuaj, qhov loj tshaj plaws uas yog Olkhon. Nws pom hais tias lub pas dej yog tsim txog 25 lab lub xyoo dhau los. Yog li ntawd, ib tug loj lub cev ntawm cov dej yog hais tias yuav tsis tau tsuas yog lub deepest tab sis kuj cov feem ntau ancient. Thiab ua tsaug rau lub varied struts ntawm Baikal nplua nuj ntiaj teb no muaj thiab fauna.

Baikal

Nyob rau hauv sab qaum teb-western pas dej yog hom twg yog Western Pribaikalye uas yog ib tug nqaim sawb thiab nce mus txog ib qhov siab ntawm 450 meters. Cov pob zeb formations sab nraum saib zoo nkauj incredibly thiab txig qhia txog tus ntug dej ntawm lub pas dej. Tshwj xeeb tshaj yog tseem ceeb spiky roob peaks. Baikal folding (nyem daim ntawv yog tsis yog-tus qauv) attracts ntau zaum nyob rau hauv lub ntiaj teb no.

Baikal

Zabaikalye pov tseg ntawm Pribaykalye thiab dej Argun. Nws ntev yog hais txog ib tug thiab ib tug ib nrab txhiab kilometers thiab cov lus dag rau sab qab teb-sab hnub poob cheeb tsam mus rau sab qaum teb-sab hnub tuaj. Nyob rau hauv ib co chaw, lub roob nyob rau hauv dej theem. Nyob rau cov qauv thiab cov uas muaj hnub nyoog ntawm lub nyem, Baikal yuav tau muab faib mus rau hauv ob peb txog tej thaj chaw. Qhov siab tshaj plaws caj yog ib qho encoder, uas nce mus txog ib qhov siab ntawm peb kis lus mev. Vim hais tias ntawm nws feem ntau, thiab muaj ntau yam climbers mus saib no tej yam ntuj tso khoom, xws li cov Baikal fold. Daim ntawv ntawm tus nyem ntawm qhov cheeb tsam yog amazing. Thiab tsuas yog nyob rau qhov no mountaintop glaciers tau muaj thaum lub Quaternary glaciations. Qhov no caj yog muaj nyob rau hauv Stanovoy system, uas yog tsim nyob rau ntawm hav thiab roob nyob nruab nrab ntawm chains. Muaj pes tsawg leeg ntawm txhua saw muaj xws li zij char thiab tiaj tus ridges. Nyob rau hauv lub yav qab teb Trans-Baikal cheeb tsam kis lowlands. Vim hais tias nyob rau hauv cov chaw thaum lub sij hawm lub xyoo uas tsis muaj ntau ntau cov dej nag, yaig dab yog sob. Nyob rau sab hnub tuaj ib feem ntawm lub Trans-Baikal vim hnyav rains tsim proluvial-ntsev loops. Lub nyem no zoo li tseem cia nrog. Nws yog tsuas yog qhia nyob rau hauv tiaj seem, uas sawv tawm sharply tiv thaiv lub siab ridges. Qhov no hom ntawm nyem hu ua Gobi.

Tag nrho cov roob ranges ntawm lub Baikal folding thiab ib tug tshwj xeeb topography, dua li lawv yog cov paj laum rau zaum.
