Qhov twg yog qhov Yenisei Ridge? Qhov xwm ntawm cov cheeb tsam no

Kawm Central Siberian toj siab, lub geologists xav nyob rau hauv ib tug txhawb txoj hauj lwm nyob rau hauv nws cov southwestern ib feem. Yuav ua li cas yog txawv nyob rau hauv lub cheeb tsam hu ua lub Yenisei Ridge? Yog vim li cas yog no qhov chaw kom ntau xim teem?

piav me ntsis txog

Ridge occupies lub tsev txhab nyiaj ntawm lub Yenisei dej, situated ntawm tus dej ntws Stony Tunguska thiab Caen. Qhov ntev ntawm lub Yenisei Ridge yog tsawg tshaj li 750 km. Lub dav ntawm lub roob yog ib lub toj 200 km. Qhov siab tshaj plaws taw tes ntawm lub caj ntseeg Enashimsky Polkan toj, nws qhov siab - 1104 m.

Qhov chaw uas tus Yenisei Ridge, conventionally muab faib ua ob lub roob ranges:

• South Yenisei tsawg roob caj.
• Zaangare.

Sib cais ntawm lub roob ranges sau raws Angara River.

geological Tom qab

Ridge geology yog tsis qoos taub. Zaum tsis tau txiav txim seb tus muaj hnub nyoog ntawm lub Precambrian sediments hais tias ua li lub pob zeb puag. Qhov no caj yog ib tug ntawm cov qhov chaw Yeneseisko Sayanskaya-fold-cheeb tsam ntawm lub txheej, uas tsim nyob rau hauv lub southwest cheeb tsam ntawm lub Siberian Platform.

Yenisei Ridge yog muaj li ntawm tuab ancient pob zeb. Muaj cim limestones, sandstones, conglomerates, shales, cuab. Roob system muaj ruaj khov tseeb quaternary nqa rau cov laus Proterozoic siv lead ua lub hauv paus. Geodynamic lub sij hawm Yeniseisky caj tsim yog suav tias yog Proterozoic. Qhov no yog hu ua cov Baikal folding. Tsis pub tsawg tshaj rau puas lab lub xyoo dhau los, tectonic qauv ntawm yav qab teb Siberia tau undergone heev heev variations. Nws sawv thiab poob. Toj siab puas lawm, ces tshiab thiab sawv rov qab. Sedimentary strata sau nyob rau hauv lub sij hawm thaum lub teb chaws yav qab teb Siberia twb sov hiav txwv. Yog li ntawd lawv muaj xuab zeb, av nplaum thiab limestone deposition (metabolic khoom ntawm lub hiav txwv creatures).

Lub ntsiab ntsuas geodynamic tej yam kev mob ntawm tsim ntawm lub continental ua kiav txhab xam tau tias yog Granites Yeniseisky caj. Qhov no yog ib tug general npe magmatic pob zeb keeb kwm, nyob rau hauv uas lub oxides ntawm silicon thiab silica yog muaj. Nyob rau hauv lub chav kawm ntawm kev tshawb thiab kev tshawb fawb nyob rau ib feem ntawm Ridge granitoid nws twb sau ntau yam kev cov ntaub ntawv thiab ob peb doctoral theses defended.

Lub complex qauv ntawm cov geological khaubncaws sab nraud povtseg thiab metamorphic pob zeb nrog sediments lub sij hawm coj mus rau tsim ntawm tsawg minerals, marble, dolomite thiab lwm yam minerals. Qhov no ua rau cov Yenisei Ridge cheeb tsam ntawm tib neeg cov xim.

nyem

Yenisei ntau muaj ntau hom struts. Entre Rios flattened los yog domed, hav dej - ntxhab, nrog zoo tob. Qhov siab tshaj plaws taw tes sawv nyob rau hauv txheej lub tsho tiv no ntawm lub caj. Lub qis tshaj yog lub sab qaum teb, Yenissei dej cheeb tsam, nws qhov siab yog 30 m. Cov kev tshuam caj Yenissei (sab qhov ncauj ntawm pob zeb Tunguska) riverbed ntaub ntawv Osinovsky chaw pib. Lwm lub chaw pib hu ua Kazachinsky yog nyob rau hauv pob zeb Cape, yog ib tug me ntsis tshaj 220 km ntawm Krasnoyarsk.

minerals

Lub ntsiab kom pom tseeb nyob rau hauv cov cheeb tsam no attracts loj loj tso ntawm minerals. Nws yog nrog lawv mas yam tib neeg kev ua ub no nyob rau hauv lub Yenisei Ridge. Muaj sab deposits ntawm hlau ore, bauxite (txhuas ore), magnesite, talc, titanite. Nyob rau hauv lub thib kaum cuaj xyoo pua, nyob rau hauv lub depths pom nplua nuj tso ntawm kub.

Nws yog ntseeg hais tias lub xub ntiag ntawm kub nyob rau hauv lub bowels ntawm lub caj scouted Yegor Ivanovich Zhmaev. Nws yog ib tug neeg ua hauj lwm ntawm lub lag luam Zotov. Zhmaev sau ntaub ntawv los ntawm lub Evenk (lub zos ib txwm), thiab nyob rau hauv 1839 muaj ntaub ntawv rau 5 kub mines sawv cev ntawm nws chaw ua hauj lwm. Thiab txij li thaum 1840 lub tiag tiag "kub maj" pib ntawm qhov Yenisei Ridge. Nyob rau hauv lub puas tawm xyoo dhau, hais txog 69% ntawm lub zus tau tej cov zoo zoo nkauj tshooj hlau nyob rau hauv Russia lees paub rau cov kub ntawm lub Yenisei Ridge.

Tam sim no, txoj kev loj hlob ntawm kub deposits los ntawm lub xeev tseem ntse. Qhov loj tshaj ntawm hnub no - Olympiada (North-Yenisei koog tsev kawm ntawv). Raws li kev tshawb kawm tag nrho kub reserves ntawm lub caj yog hais txog 1570 tons.

Ib me ntsis txog cov xwm. nroj tsuag

Yeniseisky caj nyob rau hauv ib tug cheeb tsam ntawm lub Siberian taiga. Ntawm no muaj ob hom: hauv lub yav qab teb taiga larch thiab Siberian ntoo thuv nrog tuab undergrowth. Ntoo thuv tsaus coniferous taiga - ib tug thaj slopes ntawm cov toj. Qhov siab tshaj plaws toj - treeless, lawv yog them nrog fab. Raws li ib tug undergrowth ntawm larch taiga ntau Alder, qus rose, qus raspberries, currants, rhododendron. Ntoo thuv Taiga muaj veynichny hellebore thiab undergrowth.

tsiaj

Nyob rau hauv lub roob ntawm lub Yenisei Ridge li ib txwm xim av dais, hma, mos lwj, lynx, wolverine. Ntawm no muaj ntau hom ntawm hma liab, Badger, weasel, ermine, weasel, sable, mos lwj, cov yaj thiab lwm yam tsiaj. Nyob rau hauv cov qhov chaw tau ntev hunted plaub-kev coj tus kheej cov tsiaj.

txawv cov noog nyob rau hauv cov ntoo. Lawv daim ntawv teev yog heev loj: ntawm no thiab crossbill, thiab cov Nutcracker, thiab qhov ncauj tawm, thiab woodpecker. Nrog ib tug loj tus naj npawb ntawm cov noog vim lub abundance ntawm cov noog of prey: owls, niam txiv dav thiab lwm hom. Ntawm no nws yog pom ib tug lossis loj tus naj npawb ntawm grouse thiab grouse. Lub abundance ntawm cov noog yog txuam nrog ib tug muaj zog nog puag, raws li nyob rau hauv lub hav zoov muaj ib tug ntau ntawm cov kab.
