Ali Yenisei Ridge? Chikhalidwe cha m'dera lino

Kuphunzira chapakati Siberia Plateau, Akatswiriwa ndi chidwi ndi malo apamwamba mu mbali kum'mwera chakumadzulo. Kodi zachilendo m'dera lotchedwa Yenisei Ridge? N'chifukwa chiyani malo awa kotero chidwi ziti?

kufotokoza mwa chidule

Ridge akuchita banki lamanja la Yenisei mtsinje unali pakati pa mitsinje ya miyala Tunguska ndi Caen. Kutalika kwa Yenisei Ridge ndi zosakwana 750 Km. M'lifupi mwa phiri ndi phiri 200 Km. The chimbuzi cha lokwera amakhulupirira Enashimsky Polkan phiri, kutalika kwake - 1104 m.

Dera kumene Yenisei Ridge, conventionally ogaŵikana ranges awiri phiri:

• South Yenisei otsika phiri lokwera.
• Zaangare.

Kulekana kwa m'mapiri akuthamanga limodzi Angara Mtsinje.

Geological Background

Ridge nthaka si bwino. Asayansi koma kudziwa zaka za m'dambo Precambrian amapanga thanthwe m'munsi. Malowa Ichi ndi chimodzi mwa magawo Yeneseisko Sayanskaya khola-dera la ❖ kuyanika, amene anapanga dera kum'mwera chakumadzulo kwa Siberia nsanja.

Yenisei Ridge wapangidwa ndi miyala wandiweyani wakale. Pali amalembedwa limestones, sandstones, conglomerates, shales, misampha. Mountain dongosolo ali khola atsopano quaternary kulimbikitsa pa akulu Proterozoic maziko krustalo. Geodynamic nthawi Yeniseisky lokwera mapangidwe imatengedwa Proterozoic. Zimenezi zimatchedwa ndi yopindika Baikal. Osachepera zaka miliyoni mazana asanu zapitazo, tectonic Kapangidwe ka Kumwera Siberia kakusintha yofanana ambiri. Iwo ananyamuka ndipo anagwa. Mapiri kuwonongedwa, ndiye kusinthidwa nauka. Nyanja strata anapeza m'nthawi imene gawo la Kumwera Siberia anali ofunda nyanja. Choncho iwo ali mchenga, dongo ndi laimu mafunsidwe (kagayidwe kachakudya mankhwala a zolengedwa za m'nyanja).

Zowonetsera zinthu geodynamic mapangidwe wa kutumphuka chokhala ankaona granites Yeniseisky lokwera. Ichi ndi ambiri dzina magmatic miyala chiyambi, imene oxides wa pakachitsulo ndi silika zili. Mu maphunziro ndi kafukufuku pa mbali ya Ridge granitoid lidalembedwa zambiri zokhudza sayansi ndi mfundozo angapo digirii kumbuyo.

Kapangidwe zovuta zigawo Geological ndi miyala metamorphic ndi m'dambo pa nthawi zinachititsa kuti pakhale mchere yosowa nsangalabwi, dolomite ndi mchere. Izi zimapangitsa m'dera Yenisei Ridge chidwi anthu.

mpumulo

Yenisei osiyanasiyana tichipeza zosiyanasiyana mtunda. Entre Rios flattened kapena ozungulira, mtsinje zigwa - phompho, ndi kuya kwambiri. The chimbuzi waima pa malaya akunja a lokwera lapansi. Wotsikitsitsa ndi kumpoto, dera Yenissei Mtsinje, kutalika kwake ndi 30 m. The mphambano lokwera Yenissei (m'munsi pakamwa pa Stone Tunguska) mtsinje mitundu Osinovsky pakhomo. pakhomo china chotchedwa Kazachinsky lili Stone Cape, ndi pang'ono pa makilomita 220 kuchokera Krasnoyarsk.

mchere

Chamene mderali amakopeka madipoziti yaikulu mchere. Ndi nawo ntchito makamaka okhudzana anthu mu Yenisei Ridge. Pali anapeza miyala ya chitsulo miyala, bauxite (zotayidwa miyala), magnesite, talc, titanite. M'zaka za m'ma chakhumi ndi chisanu ndi chinayi, kozama anapeza madipoziti za golide.

Iwo ankakhulupirira kuti kukhalapo kwa golide m'chikondi cha lokwera la scouted Yegor Ivanovich Zhmaev. Iye anali wantchito wa wamalonda Zotov. Zhmaev anasonkhana zambiri kuchokera Evenk (mbadwa wamba), ndipo mu 1839 yofunsira migodi 5 golide m'malo mwa abwana ake. Ndipo kuyambira 1840 weniweniwo "golide liwiro" anayamba pa Yenisei Ridge. M'zaka za m'ma chakhumi ndi chisanu ndi chinayi, za 69% ya yopanga zitsulo wamtengo Russia kudawerengedwa kwa golide wa Yenisei Ridge.

Pakali pano, chitukuko cha madipoziti zagolide ndi boma akupitiriza bwinobwino. The kwambiri lero - Olympiada (North-Yenisei chigawo). Malinga kufufuza okwana nkhokwe za golide wa lokwera ndi za 1570 matani.

A pang'ono za chilengedwe. zomera

Yeniseisky lokwera ili mu zone ya nayonso Siberia. Apa pali mitundu iwiri: kum'mwera nayonso larch ndi Siberia paini ndi m'tchire wandiweyani. Amawonda mdima coniferous nayonso - ndi otsetsereka kumadzulo kwa mapiri. Phiri lalitali - treeless, iwo ataphimbidwa ndi tchire. Monga m'tchire wa larch nayonso alder wamba, duwa zakutchire, raspberries zakutchire, currants, rhododendron. Pine nayonso ali veynichny hellebore ndi m'tchire.

nyama

Mu mapiri a Yenisei Ridge mwachizolowezi bulauni chimbalangondo, nkhandwe, mphalapala, amphaka, wolverine. Apa pali mitundu yosiyanasiyana ya nkhandweyo, akatumbu, weasel, ermine, weasel, sable, mphalapala, nkhosa ndi nyama zina. Mu malo awa akhala ankasakidwa ubweya zobala nyama.

mbalame osiyana moyo mitengo. mndandanda awo ioneka: kuno ndi crossbill, ndi nutcracker, ndi thrush, ndi woodpecker. Ndi mbalame zambiri chifukwa cha kuchuluka kwa mbalame zodya nyama: akadzidzi, hawks ndi mitundu ina. Apa izo anapeza nambala yaikulu grouse ndi grouse. Kuchuluka kwa mbalame amagwirizana ndi amphamvu forage m'munsi, monga mu nkhalango zambiri tizilombo.
