Nyob hauv ntiaj teb no tsis tshua muaj qhov chaw loj loj uas muaj lub tiaj tiaj zoo li West Siberian Plain. Minerals tso rau hauv thaj chaw no tau pom nyob rau xyoo 1960. Txij thaum ntawd los, lub pantry ntuj no tau muaj txiaj ntsig tshwj xeeb rau peb lub xeev.
Hnub nyoog ntawm pob zeb ntawm Sab Hnub Poob Siberian Plain qhia tias muaj cov peev txheej loj hauv lawv. Txoj kev loj hlob ntawm sab qaum teb tshaj plaws deposits yuav tsum tau ntxiv sij hawm thiab siv zog. Niaj hnub no, vim muaj thaj tsam loj ntawm marshy swamps hauv thaj chaw xws li West Siberian Plain, cov zaub mov raug mined ntawm tus nqi ntawm kev siv zog ntau.
Qhov chaw
Sab Hnub Poob Siberian Plain nyob hauv thaj tsam ntawm daim phiaj epihercynian. Nws yog nyob rau hauv cov teb chaws Es Xias thiab nyob yuav luag tag nrho ib feem ntawm Western Siberia, pib los ntawm lub Ural Roob thiab xaus nrog lub Central Siberian Plateau.
Cov cheeb tsam ntawm Russia thiab Kazakhstan nyob rau ntawm lub tiaj no. Tag nrho cheeb tsam ntawm cheeb tsam notshaj peb lab kilometers. Qhov kev ncua deb ntawm sab qaum teb mus rau sab qab teb yog ob thiab ib nrab txhiab, thiab los ntawm sab hnub tuaj mus rau sab hnub poob - ib txhiab cuaj puas kilometers.
Kev piav qhia ntawm West Siberian Plain
cheeb tsam no yog ib qho chaw uas muaj qhov me ntsis rugged nyem, diluted nrog me me hloov hauv qhov siab txheeb ze. Tag nrho cov no txiav txim siab qhov tseeb zonality ntawm toj roob hauv pes.
Kev piav qhia ntawm West Siberian Plain muab lub tswv yim ntawm cov yam ntxwv ntawm thaj chaw ntawm thaj chaw. Sab qaum teb ntawm thaj chaw yog dominated los ntawm tundra, thiab steppe txuas mus rau sab qab teb. Vim lub fact tias lub tiaj yog tsis zoo drained, ib feem ntawm nws yog nyob rau hauv swampy struts thiab swampy forests. Tag nrho cheeb tsam ntawm xws complexes yog ntau tshaj li ib puas thiab nees nkaum-yim lab hectares. Vim muaj cov yam ntxwv ntawm thaj chaw, huab cua hloov tau.
qauv ntawm lub tiaj
Tus qauv ntawm West Siberian Plain yog heterogeneous. Nyob rau hauv qhov tob loj muaj cov pob zeb Paleozoic, uas yog them nrog Meso-Cenozoic deposits. Cov Mesozoic suites sawv cev rau cov dej hiav txwv thiab cov teb chaws Europe deposits ntawm cov organic teeb meem.
Tus qauv ntawm West Siberian Plain qhia rov qab hloov pauv hauv huab cua thiab kev tswj hwm ntawm nag lossis daus ntawm cov phaj no. Qhov no tau ua kom yooj yim los ntawm nws qhov kev tshem tawm thaum pib ntawm lub sijhawm Mesozoic.
Grey av nplaum, av nkos, glauconite sandstones sawv cev Paleogene deposits. Lawv tsub zuj zuj tshwm sim nyob rau hauv qab ntawm lub hiav txwv Paleogene, uas, nyob rau hauv lem, txuasLub Arctic phiab nrog hiav txwv Central Asia los ntawm kev nyuaj siab ntawm Turgai Strait. Tom qab ntawd, nyob rau hauv nruab nrab ntawm lub Oligocene, lub hiav txwv no tshuav cov kev txwv ntawm Western Siberia. Hauv qhov no, Upper Paleogene deposits sawv cev rau cov xuab zeb-argillaceous continental facies.
Colossal kev hloov pauv hauv qhov xwm txheej ntawm tsub zuj zuj ntawm sedimentary deposits tshwm sim hauv Neogene. Ib lub pob zeb tau tsim uas nce nyob rau sab qab teb ntawm lub tiaj thiab muaj cov pob zeb loj ntawm cov dej ntws thiab cov pas dej. Lawv tsim tshwm sim nyob rau hauv cov xwm txheej ntawm ib tug me me dissection ntawm lub tiaj, uas yog them nrog subtropical zaub, ces broad-leaved deciduous forests. Hauv qee qhov chaw nws muaj peev xwm ua tau raws li thaj chaw ntawm savannas nyob hauv giraffes, hipparions, ntxhuav.
txheej txheem ntawm kev tsim cov zaub mov
Qhov chaw ntawm West Siberian Plain qhia tias muaj lub hauv paus folded ntawm Paleozoic [deposits. Cov deposits no yog them los ntawm ib tug cover ntawm xoob marine thiab continental Mesozoic-Cenozoic pob zeb (av nplaum, sandstone, thiab lwm yam). Qhov no ua rau muaj laj thawj xav tias hauv qee qhov chaw muaj hnub nyoog ntawm pob zeb ntawm West Siberian Plain nce mus txog ib txhiab xyoo lossis ntau dua.
Raws li qhov tshwm sim ntawm qhov poob ntawm cov phaj hauv cov pas dej ntiav, cov organic teeb meem tau sau tseg, uas tom qab ntawd hloov mus rau kev txuag hauv cov pob zeb sedimentary. Raws li qhov tshwm sim ntawm lub siab thiab raug kub kub, kev tsim cov zaub mov tau pib. Cov txiaj ntsig tau txav mus rau sab nrog lub siab qis tshaj plaws. Raws li qhov tshwm sim ntawm cov txheej txheem no, cov roj tau ntws los ntawm lub submerged mus rau lub xeev uplifted, thiab cov pa roj sib txuas tau nce raws cov npoo ntawm cov pas dej. Sab saum toj qhov chaw ntawm qhov siab tshaj plaws ntawm cov bass muaj ib lub pob zeb sedimentary - av nplaum.
Muaj peev txheej
Ua tsaug rau kev ua haujlwm ntawm geologists hauv thaj chaw xws li West Siberian Plain, cov zaub mov pom hauv thaj chaw no tau dhau los ua lub hauv paus muaj zog rau kev loj hlob ntawm Western Siberia. Nws muaj cov khoom siv xws li cov pa roj carbon monoxide, hlau ore, xim av thee, roj.
Cov roj ntau ntau tau tsim tawm ntawm cov dej tsim hauv Western Siberia. Mos sedimentary pob zeb yog yooj yim rau laum. Ib qho ntawm cov nplua nuj thiab zoo tshaj plaws roj teb yog West Siberian Plain. Minerals tau raug mined ntawm no ntau tshaj li tsib caug xyoo. Lub pas dej loj tshaj plaws yog West Siberian roj thiab roj phiab. Nyob rau hauv lub ciam teb ntawm Khanty-Mansiysk synecise, raws li zoo raws li lub Krasnoselsky, Salymsky thiab Surgutsky cheeb tsam, nyob rau hauv lub Bazhenov tsim, muaj cov loj tshaj plaws shale roj reserves nyob rau hauv peb lub teb chaws. Lawv raug khawb ntawm qhov tob ntawm ob kilometers.
Lub dab tshos ntawm cov nyiaj xoob xoob npog lub qab ntug ntawm cov dej tshiab thiab cov dej ntxhia hauv av. Kuj tseem muaj qhov kub thiab txias, qhov kub ntawm qhov sib txawv ntawm ib puas mus rau ib puas thiab tsib caug degrees.
West Siberian Plain: minerals (rooj)
| npe nyiaj | Mineral resources |
| Sokolovsko-Sarbaysky, Kacharsky bass | hlau ore |
| North Sosva, Yenisei-Chulym thiab Ob-Irtysh bass | lignite |
| Ayat deposit | nickel, thee, chromite, bauxite |
| Lisava field | cob alt, khoom siv hauv tsev, nickel, thee |
| pas dej ntsev nyob rau sab qab teb ntawm Western Siberia | ua noj thiab Glauber's ntsev |
| Yakutsk deposits | pob zeb diamond tubes |
| Lensky, Tunguska, Irkutsk basins | coal |
| Southern thiab qaum teb tso nyiaj ntawm West Siberian Lowland | roj |
Yog li, cov qauv ntawm Sab Hnub Poob Siberian Plain qhia txog lub hnub nyoog ruaj khov ntawm pob zeb ntawm thaj chaw no thiab muaj cov nplua nuj nyob hauv pob zeb. Txawm li cas los xij, muaj teeb meem ntawm kev tsim roj thiab roj. Nws nyob rau hauv tej yam ntuj tso nyuaj. Lub neej thiab kev ua haujlwm ntawm cov neeg nyob rau sab qaum teb yog qhov nyuaj heev los ntawm cov huab cua hnyav thiab cua daj cua dub. Cov av nyob rau sab qaum teb yog them nrog permafrost, yog li kev tsim kho tsis yog ib txoj haujlwm yooj yim. Thaum lub caij ntuj sov, cov kab nqus ntshav nce ntxiv, uas tsim teeb meem rau cov neeg ua haujlwm.
Siv qhov xaus
Hnub no, qhov teeb meem ntawm kev tiv thaiv thiab kev siv cov peev txheej ntawm Western Siberia tseem cuam tshuam. Predatory kev puas tsuaj ntawm cov xwm nyob ib puag ncig tuaj yeem ua rau muaj kev puas tsuaj loj. Nws yuav tsum raug coj mus rau hauv tus account tias nyob rau hauv lub ntuj system txhua yam yog interconnected, thiab yog li ntawd ib tug yuav tsum siv zog tsis txhob cuam tshuam nws kev sib raug zoo.
