Somugumisiro, iye akaumba munhu moraine? diluvium

Residues wamatombo hwakazununguswa rechando panguva dzakasiyana marefu, kwamakadarika akaumba moraine. Sezvo chikamu vakawanda ichi siyana dzinogona kuwanikwa ivhu nezvimedu, jecha, mavhu residues, uyewo zvitarisiko siyana uye Sizes mabwe kuti striated mune imwe nzira uye vane grooves yawo pamusoro.

Glacial deposits uye landforms

Mazizaya dzinoshanda paumbwe kwakaita nzvimbo yacho Wepasi. Ivo akaumba mune okunze dzinodengenyeka ari polar kumatunhu ari mukuru kukwira mumakomo. rechando kufamba kunokonzerwa rimwe unhu chando, anogona kuchinja nzvimbo imwe kumanikidzwa. Panguva iyoyowo chinokosha nzvimbo inoremekedzwa ari plasticity echando, iyo chinowedzera maererano tembiricha. Kazhinji, sangano kunoitika muna 30-mita udzamu.

Kana uchityaira kungachinja yepakutanga chimiro chando vakaumba panofamba, makatsemuka, mipendero siyana zvitarisiko uye hukuru. Kana kumhanya kufamba, ipapo Paavhareji vane diki, richisvika anenge 100 metres pagore. Somugumisiro kunyunguduka mazizaya vakaumba Rwako pakati meltwater uye rose glacial makungwa, unosanganisira nokuumbwa itsva, akachinja Zvinoumba deposits uye kuchinja kwenzvimbo.

Mhando glacial deposits

Ingangoita muzvitatu panyika rakafukidza mazizaya kusvikira. Zvino nhamba 10%. Kunyange chete glaciation kunogona kukonzera kuchinja pose. All deposits chando inogona kupatsanurwa muzvikwata zvikuru zviviri: arongwe uye unsorted.

Kupindura mubvunzo, zvokuti akaumba moraine, zvakakodzera kujekesa glacial deposits kwazvinoita chero marudzi. Zvakakwana unsorted hazvigoni zita, kunyange ndoweboka ichi. Morena munhu havaratidzi arongwe Marara, kana zvakananga vachiwirirana dzakamirira Glacier.

Mumwe chikamu zvinosanganisira glacial vakasara arongwe mvura. Vachiri akakamurwa pamusoro Division pedyo rechando, zvakananga kuonana nayo, uye mapfupa kuti dzave kusuka mhiri kwenzizi kana nzizi vakanyauka.

Deposits pamusoro kuonana rechando

Sorted glacial deposits chaizvo siyana yakarongeka, kuburikidza paunogona uchengete variability siyana zvokuyamura. Of mubereko mukuru vari deposits pamusoro neVadzidzi rechando. Akadaro inotungamirwa sezvo kame zvikwiriso akabva kubudikidza kuunganidza kwemarudzi akasiyana-siyana pamwe kumicheto rechando chando, iri kudiwa mumipata uye reservoirs. Kana chando ikavhunduka, zvimedu vakaparadzaniswa mumativi mumipata. Avo vanowira pasi chando, zvakakonzera collapses uye Madhaka. A kugomo rinonzi kamami akadzidza.

Eskers - mumwe Dzakarongwa glacial emadhaka, akafanana chinozunguzirwa akafanana anooneka zvikuru nemichinjiziri, zvinosanganisira guru matombo uye jecha mavhu. Noumwe nguva vari pasi mugero drains the uye kashoma akasarudzwa pamusoro pemvura.

Moraine: asi hunhu E. V. Shantseru

moraines Major akaumbwa nezvimedu zvakasiyana kukura, kubvira nevhu uye ndokuguma pamwe dombo. Mamirire zvinhu zviri areal kuwanika hunogara erudzi clastic zvokunyama uye hapana akaturikidzana pachena. Zvimwe chinoumbwa nezvinhu izvi mhando moraine, dzinoratidzwa yakakwirira arambe achirema, kunogona kuitika residues yokucheka mapuranga, atypical zvakakwana nharaunda iyi. Nokuda kwayo mukurumari, ichi zvinhu zvingashandiswa nokushingaira pakuvaka mabasa.

Murwiyo uye ruvara zvechadenga moraine ane simba guru Geological nemamiriro rechando. Kana inonyunguduka pamupata mawere mumwe nhamba akaturikidzana longline mhando kuti zvingaite rose moraine Miro. Dangwe deposits uye nokusazvibata masarasara vari ndokudzora kana nokushambidzirwa zvakakwana uchanyangadika mvura, hwekutambudzika nzizi gomo.

Morena rinoumbwa glacial idzodzo

Glacial boka sediments dzinoratidzwa siyana zvikuru, uye zvinosanganisira:

• glacial moraines;
• glaciofluvial sediments kubva kubvunda mazitombo echando;
• limnoglyatsialnye vakasara glacial zhinji;
• solifluction deposits;
• glacial zvomumvura sediments.

Somugumisiro, iye akaumba munhu moraine? Izvi chando idzodzo deposits havana ruzivo arongwe uye zvimedu vane chimiro murwi zvakasiyana kutigumbura, mabwe, zvakavhenganiswa jecha uye nevhu. Pakutanga, mukanyiwa wose zvachose zvakavhiringika nzira, asi hazvisi. Pamusoro pedyo uye kunyatsoongorora inogona vakagumisa kuti utsotso echando yomukati akaturikidzana moraine Kutamiswa kupinda nheyo dzaro. Asi dzimwe nguva yakasimba pasi-Ice hova kushambidzwa kwazvo moraine, somugumisiro chiri vakawanda guru boulders.

mhando nhatu moraines

glacial moraines vari vatatu marudzi. Internal glacial moraine inoumbwa ne kupinda marara muruvanze rwomukati akaturikidzana echando. Munguva kwebasa mazizaya kunosiyana Nzvimbo anogara aine kuwa munzira pamatombo, boulders, jecha uye ivhu. Bottom moraine inoumbwa tichibvisa uye tama dombo residues, uye zvakare, zvichienderana zvimwe zvinhu nesimba uye kumhanya kufamba anotakura zvinhu inounganidzwa pacharo, nechigadziko uye zvakadzika akaturikidzana echando.

Terminal moraines vari kuumbwa, ave mutemo, pamusoro pamuuyo rechando. matombo aya akazara nemavhinga vari aumba apo rechando kumucheto yaiva refu nguva panzvimbo imwe, uye panguva imwecheteyo Glacier akanunura detrital zvinhu pano dzose itsva. Izvi zvinogoneka kuna zvairambidzwa kwebasa rechando nokuda chero pamaberere kana zvimwe zvipingamupinyi. End moraine nezvechitarisiko chavo fananei zvikomo anooneka zvikuru nemichinjiziri kuti zvinofanana kune mumwe. Zvivako dzakadaro dzinosanganisira kwete chete dombo rakasimba, asi kusunungura akaturikidzana kwerwizi kana nyanza sediments akatorerwa rechando.

Moraine: zvokuimba kupatsanura

In ayo akafanana, zviri moraine ane kusiyana chaizvo. Zvinotevera mhando glacial moraine:

• Rocky;
• jecha;
• jecha loam;
• loamy;
• ivhu.

In yakaisvonaka chimiro moraine zvisinganyanyi kuitika, kazhinji ndepana dzakananga nzvimbo yakavhenganiswa sezvamunoita. To nemazvo rokuongorora uye kudzidza glacial deposits, mumwe kudzidza pamatombo uye zvinhu hazvina kukwana, unofanira kunzwisisa ukama hwavo paragenetic nevamwe masangano.

Special zviri moraine

Multi-chidimbu zvinhu anosarudzwa rechando zvishoma nezvishoma mumatope, apo moraine kuumbwa, izvo zvinogona zvose kutakurwa (chinjwa) uye kunonoka (chando aparadzana muaizi idzodzo magene marudzi). Morena anogona kuvapo ari yoga chimiro glacial nakuyenda. Ainyanya rinoumbwa yokusazvibata sediments kuti anowanzoramba nekuda mumapani, drumlins uye moraine zvikomo uye reliefs.

Water-glacial deposits vakawana mukufamba sedimentation chokumusoro akaturikidzana ari rechando. Morena ichi mhando izere zvinonyadzisa nejecha uye boulders makuru. End deposits akaumba panguva yokupedzisira nguva dzose rechando kutamira pakutanga utsotso. Moraine Zvinoumba zvicherwa (Goldstone, Mika, feldspar) iri zvakananga novimba pamatombo pachavo podmyatyh pasi chando muviri. Zvinonzi nemarererwo nezvenzvimbo glacial moraine kurema uyewo rokutendeutsa pezvakaitwa residues panguva kufamba kwenguva refu.

Glacial deposits zvose Continental uye makomo. Ivo zvisingapindirani dzinoverengeka parameters, chidimbu dzinotsanagura rokuyamura inotungamirwa uye chimiro, akafanana uye emadhaka mhando.
