Iyo Archaic aeon yakaratidzirwa neyemeteor shawa
Iyo Archaic Aeon ndiyo nguva inotangira iyo Hadic Aeon. Iyo inovhara angangoita zviuru mazana matatu kusvika mazana maviri nemazana mashanu emakore apfuura. Tichiri mukati mePrecambrian Supereon, asi ndiyo yekutanga iyo yatinogona kutanga kusiyanisa mazera. Kufanana neyakatangira, yaive zvakare yakakanganiswa zvakanyanya nezvakanga zvichiitika musolar system.
| Supereon | Eon | Mamirioni emakore |
|---|---|---|
| Precambrian | Proterozoic | 2.500 a 540 |
| Precambrian | Zvekare | 3.800 a 2.500 |
| Precambrian | Hadic | 4.550 kusvika 3.800 XNUMX |
Kana iyo Hadic aeon yaive mavambo uye kutanga kwenyika yedu, kukosha kweyeArchaic aeon iri mune mavambo uye mavambo ehupenyu. Izvo zvinofanirwa kuwedzerwa kuti kutsanangura uye kujekesa nguva chaiyo yechiitiko chimwe nechimwe munhoroondo yepasi redu, zviri kana zvisiri, zvakaoma kwazvo. Nguva dzinozivikanwa, dzinotsanangurwa, asi dzichisimbisa zvakare, hapana zuva chairo rechinoitika chese. Tichishandisa chirevo ichi segwara, ngatitevere nzira yatakasiya mazuva mashoma apfuura.
Iwo haasi chero matombo, iwo maStromatolites. Mubhawa reShark Bay, Australia.
Iyo inozivikanwawo seArchaeozoic, ndiyo imwe yenguva dzakareba kwazvo dzakambovapo. Iyo inoumbwa muhuwandu hwayo, ingangoita chetatu chenguva izere yepasi redu. Mumanyoro ekare, iyo Archaic aeon yaimbove isina kusiyaniswa kubva kuHadic, kubatanidza nguva mbiri seimwe. Zita rekuti Archaic, iro rinobva muchiGiriki chekare, rinoreva "kutanga" kana "mavambo", nekuda kwezvikonzero zvinokurukurwa. Chinhu chakakurumbira kwazvo panguva iyi yaive shanduko yekukura kwepasi. Izvi zvinotitungamira kuti tifunge nezve yakakura ndiro tectonic kufamba, izvo zvinotungamira kuti tifunge kuti chimiro chemukati chenyika chaive chakafanana chaizvo nemabatiro atinochiziva nhasi.
Kuti unyatsonzwisisa kuverenga kwenguva kweiyi eon, inofanirwa kuve yakakamurwa pakati peakakura mana. Imwe neimwe yakatarwa neshanduko huru.
| Eon | Era | Mamirioni emakore |
|---|---|---|
| Zvekare | Neoarchic | 2.800 a 2.500 |
| Zvekare | Mesoarchic | 3.200 a 2.800 |
| Zvekare | Paleoarchic | 3.600 a 3.200 |
| Zvekare | Eoarchic | 4.000 / 3.800 3.600 kusvika XNUMX XNUMX |
Tsananguro inokurumidza kwazvo yeArchaeozoic inogona kutsanangurwa kubva pazviitiko zvikuru zvakaitika. Yekutanga heterotrophic uye photosynthetic anaerobic maseru akaonekwa (cyanobacteria). Iwo ekutanga masisitimu eakaberekerwa mavambo anotangawo, iyo stromatolites. Naizvo makondinendi ekutanga anoonekwa pamwe nekuumbwa uye kutanga kwema tectonic mahwendefa. Oxygen inotanga kusunungurwa mumhepo. Uye kunyangwe iri nguva yakatarwa nekudonha kwemameteorite, inguva zvakare iyo kunaya kukuru kwemvura kwadzo.
Iyo Eoarchic
Nyika ichiri mukuumbwa nguva dzose, mabota uye kuputika kwaive kwakajairika
Yakanga iri nguva yakagara makore mazana maviri / mazana mana emazana emakore. Zvichienderana nesosi inobvunzwa, sezvo International Commission yeStratigraphy isingazive muganho wezasi wenguva. Zvinosiyana nezvimwe zvese, mukuti inguva iyo inoonekwa zvisikwa zvipenyu zvekutanga. Inowanikwa makore 200 bhiriyoni apfuura. Nguva yakazotevera, makore 400 bhiriyoni apfuura, yekutanga chemosynthetic zvipenyu zvinoonekwa. Izvo zvipuka izvo hazvidi kuti zuva riwane simba razvo.
Iyo iripo yekuyerera kuyerera yaive yakapetwa katatu kupfuura iyo yazvino, mamiriro ekunze aivepo aidziya kwazvo. Izvi hazvina kungotsanangudza zera iri, asi zvakamakisa eon yese. Chete kubva kune inotevera, iyo Proterozoic, kuyerera kwacho kunogona kuve kwakapetwa ikozvino. Uku kuwedzera kwekuwedzera kwaigona kuve kwakakonzerwa nekupisa kubva pakuumbwa kwesimbi yepasi repasi. Zvakare kune yakakura kugadzirwa kweiyo radiogenic kupisa neapfupi-akararama radionuclides, senge Uranium-235. Zvakakodzera kutaura nezve chiitiko chekuputika chakavapo kutenderera pasirese, pamwe nekuputika kwemakomo nemakomba emabota. Dzese dzakaramba dzichikonzera nzvimbo dzakawanda dzinopisa.
Iyo Paleoarchic
Anoxygenic mabhakitiriya anoonekwa. Ndokunge, vano photosynthesize, asi havadzinge oxygen
Inosanganisira makore ari pakati pemamiriyoni matatu nemazana matatu nemazana matatu. Mafomu ehupenyu anozivikanwa kwazvo anotanga. Pano, izvo zvipenyu zvave zvichikura uye zvatova tinowana microfossils yakachengetedzwa zvakanaka kubva pamabhiriyoni 3.460 emakore apfuura, muWestern Australia. Iyo stromatolites.
Utachiona hunotanga photosynthesize, kuwana simba kubva kuzuva. Pakutanga ivo vaive anoxygenic, ivo vachiri vasina kupa oxygen. Parizvino, tinogona kuwana rudzi urwu rwephotosynthesis mumabhakitiriya egirini kubva kusarufa uye kwete kubva kwesarufa, uye hutachiona hwehute. Rudzi urwu rwekuwana simba rwakatangwa kusvika kupera kweyeArchaic eon.
Zvimwe zvinhu zvakatsanangura ino nguva. Zvinogoneka kuti mubatanidzwa wemamwe makatoni wakaumba Vaalbará, inova ndiyo fungidziro yekutanga supercontinent yaivepo. Izvo zvinofanirwa kucherechedzwa kuti havazi vese nyanzvi vanobvumirana kuti yaivepo. Kwaive zvakare kupera kwekunonoka kwakanyanya kwemeteor kugeza. Kune ese apfuura mazana emamirioni emakore, Pasi rakarohwa navo.
Iyo Mesoarchic
Kuonekwa kwekunyepedzera kwepasi munguva yekutanga yechando
Yakagara pakati pemakore zviuru mazana matatu nemazana maviri nemazana masere. Iyo yekufungidzira supercontinent Vaalbara ichatsemukayaizotevera munguva ino, ichipa nzira kuNeoarchic. Chinhu chekusimbisa ndechekuti paive kwenguva yekutanga glaciation pasi. Kugona kufungidzira kuti yaifanirwa kutaridzika sei, mvura iri mumakungwa inogona kuve nesimbi yakawanda. Izvo zvaizopa iyo greenish hue. Uye mumhepo yakatekesherwa zvakanyanya nekabhoni dhayokisaidhi, matenga airatidza zvitsvuku.
Kunyangwe paine chishuwo chitsva mukuumbwa kwemahwendefa emakondinendi, havafanirwe kunge vakatora zvinopfuura gumi nezviviri muzana. Pane rimwe divi, makungwa angadai asina kumira kuumbwa. Kumeso kwavaizosvika kwaizove kutove 50% yevhoriyamu yavainayo izvozvi.
The Neoarchic
Chitarisiko chekunyepedzera chaizotanga kuoneka nekuda kwecyanobacteria
Iyo yekupedzisira nguva uye kupera kweArchaic eon. Akanzwisisa pakati Makore 2.800 2.500 kusvika XNUMX XNUMX emakore apfuura. Mabhakitiriya akaenderera mberi kukura, uye atove tanga photosynthesize kuburitsa oxygen, cyanobacteria. Yakakura mamorekuru oxygenation inotanga pane iyo nyika ine mhedzisiro yayo mune inotevera eon. Iyo hombe huturu kuunganidzwa kweokisijeni kwaizopedzisira kukonzeresa iyo yakakura oxidation gare gare.
Ma protocontinents iyo yaivepo, saVaalbarah, uye imwe inonzi Uri, dzaive diki muhukuru. Kwete chete nekuti ivo vakatanga kufambidzana, asi nekuti kuhukura kwayo kwaizvimutsidzira. Kupesana nekugadzikana uko makondinendi anozviratidza kwatiri nhasi. Panguva iyoyo, kuputika kwemakomo kwakatanga kuonekwa, yakaita basa rakakura, pamwe chete nemapoka uye makratoni ayo aibuda.
Izvo zvaisazove kusvika rinotevera eon, iyo Proterozoic, uko kwakanyanya kuomarara mafomu ehupenyu akatanga kuoneka.
Kana iwe wanga uchishuwira kuziva kutanga kwezvose. Kuzivisa iyo Hadic aeon, kutanga kwenyika yedu. Iko iko zvakare kunoonekwa, iko kunoshamisa kuumbwa kweMwedzi.
