Nqe lus piav txog kev nyiam

Ilmensky glint yog lub ntuj tsim, thaj chaw ib puag ncig nyob hauv Shimsky thiab Starorussky koog tsev kawm ntawv ntawm cheeb tsam Novgorod, nyob rau thaj tsam sab hnub poob ntawm ntug dej hiav txwv sab qab teb ntawm Lake Ilmen, nruab nrab ntawm Delta ntawm Shelon thiab Lovat dej.

Ilmensky Klint yog qhov siab, liab qab-cliff-ledge. Nws qhov ntev yog 8 km, qhov siab tshaj plaws - txog 15 meters - nyob nruab nrab ntawm cov zos Korostyn thiab Pustosh. Ntxiv mus, klint kis mus rau sab hnub tuaj, maj mam txo qis thiab, vim li ntawd, xaus. Los ntawm nws, nyob ib puag ncig ntawm lub zos Ustreka, Dej Psizha thiab Savateika kwj dej ntws mus rau hauv Lake Ilmen. Ilmensky Klint yog qhov dej hiav txwv Devonian ntev tshaj plaws ntawm Lavxias Plain thiab yog lub tsev khaws puav pheej geological tshwj xeeb.

Cov xwm txheej huab cua, ua ke nrog nthwv dej nthwv dej, maj mam tshem cov pob zeb dag hauv txheej: sab hnub poob, cov no yog av nplaum, xuab zeb tshwm saum lawv, thiab tom qab ntawd limestones. Qhov ua txhaum ntawm phab ntsa limestone tau tsim los ntawm kev ua ntawm Quaternary glacier, uas tau txav cov pob zeb loj ntawm cov pob zeb uas muaj suab thaj tuaj ntawm no.

Nyob rau ntawm ntug dej hiav txwv sab hnub poob sab hnub poob, raug nthuav tawm, thaj tsam qis dua uas tau sawv cev los ntawm qhov hu ua Ilmenian txheej. Lawv cov tuab nyob hauv qee qhov chaw yog 10-15 m. Ntawm no koj tuaj yeem pom cov xim ntsuab-ntsuab nrog cov xim av nyias txheej thiab cov xuab zeb dawb nrog cov seem ntawm cov tsiaj thiab cov ntoo qub. Cov xuab zeb muaj cov seem ntawm cov plhaub thiab cov pob txha ntawm cov ntses qub, nrog rau lub plhaub ntawm chara algae. Cov av nplaum tau nthuav dav los ntawm cov neeg sawv cev ntawm cov tsiaj hiav txwv tob.

Qhov kev tsim geological ntawm ib lub sijhawm tau nyiam cov kws tshawb fawb thiab kws tshawb fawb ntau yam. Piv txwv li, Academician I. G. Lehman (1719-1767) yog thawj tus neeg tshawb xyuas Ilmensky ci. Xyoo 1779, tus kws tshawb fawb E. Laxman tau tshuaj xyuas cov ntaub ntawv paub thiab xaus tias thaum ub qhov chaw no tuaj yeem yog ib feem ntawm lub hiav txwv lossis pas dej. Xyoo 19th, tus kws tshawb fawb V. M. Severin tsim cov lus piav qhia ntxaws ntawm sab qab teb hnub poob ntawm Lake Ilmen. Tsis tas li, thaj chaw no tau kawm los ntawm kws tshawb fawb N. Ya. Ozeretskovsky txoj kev. Nws txoj kev tshawb fawb hauv 1805 tau xav txog hauv kev tshawb fawb thiab keeb kwm hauv zos ua haujlwm "Txoj Kev Taug Kev ntawm Tus Kws Kawm Ntawv N. Ozeretskovsky raws cov pas dej Ladoga, Onega thiab ib puag ncig Ilmen." Xyoo 1840s, Ilmensky glint tau kawm los ntawm tub ceev xwm tub ceev xwm, tus saib xyuas toj roob hauv pes (tom qab - tus kws tshaj lij) G. P. Gelmersen. Nws txheeb xyuas qhov tsim ntawm Ilmensky Klint li Devonian tso nyiaj. Xyoo 1849, Scotsman R. I.

Xyoo 1962, los ntawm kev txiav txim siab ntawm kev mus ntsib ntawm Academy of Sciences ntawm Soviet Union, Ilmensky Glint tau tshaj tawm tias yog lub ntuj tsim, uas yuav raug tiv thaiv los ntawm lub xeev. Yog li ntawd, txhua yam haujlwm uas tuaj yeem rhuav tshem lossis hloov pauv cov toj roob hauv pes hauv ib cheeb tsam tau txwv. Txawm li cas los xij, nyob rau ib nrab ntawm lub xyoo pua 20th, cov pob zeb lim zeb tau txua hauv cov dej ntawm tus dej Psizha, uas yog siv los tsim txoj kev hauv zos. Qhov no ua rau muaj kev puas tsuaj tsis zoo rau lub geological monument.

Txhua qhov kev tshuaj xyuas av, kev ua liaj ua teb thiab kev tsim kho kuj raug txwv nyob rau thaj chaw no. Ntxiv rau kev tiv thaiv lub xeev, Ilmensky Glint yog nyob hauv kev saib xyuas ntawm ecologists los ntawm Veliky Novgorod. Txij li xyoo 2001, nws yog thaj chaw tshwj xeeb tiv thaiv ib puag ncig. Ntxiv nrog rau tus nqi ntawm kev tsim geological nws tus kheej, nws muaj cov tsiaj tsawg thiab tiv thaiv hom tsiaj (piv txwv li, orchids). Kuj tseem muaj qhov hluav taws xob tawm mus rau saum cov ntxhia thiab cov dej tshiab.

Lub keeb kwm geological tuaj yeem nkag tau, yog li ntawd, nws tso cai rau koj koom nrog cov tub ntxhais kawm thiab cov tub ntxhais kawm hauv txoj kev kawm thiab siv nws ua qhov chaw ncig tebchaws.
