Sirt Kutalika okwana phiri. Ali zomwe zili General Sirt?

Total Sirt - ndi kumveka kwa okwera yachonde ngati, amene kugona pa expanses wa Russia ndi Kazakhstan. Ikani okulira pa mitsinje yambiri. Pali makumi chiyambi mitsinje. Chiyambi cha phiri imatengedwa Kuyan-matchalitchi anayamba - mapiri, kuyambira ku malire chapamwamba za Kama Mtsinje lamanzere gombe tributary wa White Mtsinje.

Chiyambi cha dzina

Mawu "Sirt" akupezeka m'zinenero awiri - Turkey ndi Chitata. Mu Turkey amatanthauza "phiri, chitunda". M'chilankhulo cha Chitata amatsogoza izo mochuluka kwambiri. Pogwiritsa ntchito mawu amenewa akutanthauzanji Chisa lokwera okulira vodopusk, vododerzhu ndipo anagubuduza chokwera phiri kulekanitsa mtsinje wamanja.

Mawu oyamba mu dzina la malo "General Sirt" ali awiri Mabaibulo a anayambira. Malinga E. A. Eversmanna, mawu akuti "wamba" inatuluka mu mutu, chifukwa phiri kuti asiyanitse watersheds awiri. EM Murzaev kukhulupirira kuti mawu akuti "ambiri" Ufumuyo dzina la Sirt chifukwa mbali ya ntchito m'dziko m'dera.

Anthu nthawi yaitali, ukhale gawo pa phiri. Russian ndi Chikazaki alimi agwiritsa ntchito kwa msipu dziko. Ndipotu, dziko kukwezeka zigwa anali ambiri Kazakhs ndi Russian. Choncho dzina la dzina malo - zomwe zili General Sirt.

Udindo Hrs wa okwera

Steeply mumbali akutambasula m'chigwa cha m'dera Orenburg, Saratov ndi Samara zigawo. Iye kusesa m'mayiko a Kazakhstan ndi ili kum'mwera kwa Bugulma-Bebeley phiri. Kummawa mapiri m'chigwa cha m'mphepete mwa otsika kum'mawa kwa Volga, kumene ndondomeko ya Bezenchuk-Khvorostyanka. Choncho malo ake kuwonjezera pa malangizo easterly ndi pafupifupi 500 makilomita. Ndipo analanda m'dera pakati Wamkulu ndi Wamng'ono Irgiz.

Mu malire kumpoto kwa zigwa za mapiri anathamangira mu mtsinje Samara. M'dera Orenburg izo limatulukira M'madera a zitunda a chigawochi ndi juts mu madzi a Kinel Small. Kummawa, m'chigawo cha m'gawo lake ndi oyenera kuti phazi la mapiri a Urals Kumwera. Kuchokera woyera tsitsi Rifey phiri anapambulwa chimathandiza. Kodi pali okwana Syrt pamwamba Kadulidwa Volga, umene zitunda dongosolo amachita mbali okulira mabeseni ndi inali pakati pa mitsinje awiri - Volga ndi Ural.

Kufotokozera za dera la kumadzulo kwa phiri

Sirt ndi chidagawika patatu - kumpoto, kum'mawa ndi kumadzulo. Zitunda, atabalalika kum'mawa, ndi kukula msinkhu. Mwambamwamba (405 meters) imatengedwa kuti ndi phiri m'kati Nyamuliranani mphumi (Aka - Arapova phiri). Apa pali chizolowezi kuonjezera kung'ambika pamwamba.

Syrty ili kummawa mpaka kumadzulo malangizo, akusiyana kutchulidwa asymmetry wa malo otsetsereka. Kum'mwera, iwo ali ozizira, ndi kumpoto M'malo mwake, canopies. Watersheds mu chapakati dzenje ndipo mbali kuti steeply mumbali pamwamba. Malinga interfluves kudutsa m'madera Sheehan - ozungulira outliers.

Features Syrt kumpoto

Mbali wakumpoto wa Syrt "cholizira" pakati pa Big Kinel ndi Samara. malowa amaoneka ngati chisa dongosolo interfluves Ndikuchepetsa ndi otsetsereka m'goli. Msinkhu mwala zitunda kwanthawi mkati mamita 220-300. The chimbuzi - phiri Kuli. msinkhu wake anafika chizindikiro mamita 333. Volcano lili pakati pa mitsinje aumbike mwa makhwawa monga Small ndi Borovka Kinel.

Dera la kumadzulo kwa phiri

Mu kumadzulo kwa unyolo lathyathyathya-steeply mumbali mapiri amatchedwa Blue Sirt. Anatenga kuyamba kumwera chakumadzulo, Ayala kumpoto pamodzi mizere kuti osonyeza Samara ndi Orenburg zigawo. Low mapiri analenga kugawa kwa Samara ndi Chagan. Kutalika pazipita (273 m) pano pa Grishkina mapiri.

Wapakati okwera wa mamita General Syrt 190-240. Choncho, kukwezedwa si chikhalidwe choona mwa phiri. chizindikiro chake apamwamba ndi phiri m'kati Kuyan-matchalitchi anayamba. kutalika kwake si upambana mamita 619. Ku mbali ya phiri monga yaing'ono yachonde ngati phiri.

mpumulo

Cacikulu Syrt ali mpumulo zofunda-tiered kapangidwe ndi outliers. Kumwera kwa phiri pang'onopang'ono utachepa ndi flattens. Chifukwa, kumanja banki bwalo la Ural Mtsinje bwino anaphatikizidwa izo. Pansi anati malo latitudinal nyumba tectonic ndipo anatambasula mu migodi ticker mwala kuti anapanga interfluves zigawo kugwa ukutsika kum'mwera, kumene kuyambira pa Caspian beseni.

Entre Rios, anafola mwa njira iyi, dulani mzere kunsi kwa asymmetry zakuthwa zigwa za mitsinje. m'zigwa zakuya ndi lathu ndi ambiri, nayenso lagawidwa mapiri angapo zitunda asymmetrical, amene kubweretsa kafukufuku wakapangidwe kazachilengedwe wapadera.

Otsetsereka kum'mwera ali otsetsereka, ngati kukadulidwapo. Otsetsereka a kumpoto ndi ofatsa, nthawi, anatambasula makilomita ambiri. kumapazi awo mosadziwa kuphatikiza ndi masitepe pamwamba floodplain ndi, anapanga kumanzere m'mbali mwa mtsinje wa beseni.

Geological mbali

Common Hill Syrt unakhazikitsidwa pa shales, marls, sandstones, limestones, shales, ndi madipoziti choko siltstone. The heterogeneity a m'dambo kupanga mpumulo, bwanji chikhalidwe cha amacheka kukokoloka.

madera kumpoto ndi mabacteria clayey marl ndi contours yosalala. Places ndi sandstones mwamphamvu apangidwe amasiyana reliefs kwambiri indented. Pamwamba ukryvshaya miyala kuligaŵa kuchepetsa zigwembe ndi zisa okulira.

Kum'mwera, General Sirt apangidwe flattened ostantsevo-liwiro Mesopotamia. Pano phiri kusokoneza saline-mzikiti tectonics. Mtunda yosiyana anayamba mchere kwambiri ndi laimu karst, kukhala chifukwa cha zolakwa nisin yaikulu lathyathyathya matendawa, pansi pa mbali zosiyana za phiri.

Kumadera kumene pali zotsala za zomwe zili watersheds boulders zakhala zikuzunza m'miyoyo perforated quartzite, sandstones khwatsi ndi conglomerates. Pa chigwa okwera anapanga njira eolian.
