Palaeozoic

The Paleozoic Era ndiye refu Danho zvakakwana okukura Nyika. Vava nemakore mamiriyoni 370.

Yatangwa nzvimbo huru munyika panguva kuguma Proterozoic yaitonga, kuti Palaeozoic yaitonga vakatanga yakakura teura makungwa. Maererano Vanodzidza zhinji, apo paiva huru imwe chinogumbura nyika unonzi Pangea ( "yose" iri mumutauro wechiGiriki). Kumativi ose rakakomberedzwa mumakungwa. With ichi anovhara huru dzakawira vega pamusoro nguva. Saka Paleozoic yaitonga yaiva nguva paumbwe nheyo ramangwana yacho kondinendi. Munguva pakuzadzisa Nyika, nhengo iyi yaigona hwakawedzera, kubatanidza (kuburikidza orogenic pezvakaitwa) kana kuderera, nokuputsa zvakare zvidimbu, izvo zvinogona huchipera zvishoma nezvishoma kusvikira nguva hakusati dzatora nzvimbo ano makondinendi.

Pfungwa chokutanga "Continental vasakukurwa," akadaro Alfred Wenger (German geologist). Maererano naye, pakutanga, Pangea rwakakamukana Gondwana uye Laurasia.

The nguva yacho Paleozoic yaitonga inokamukana kupinda Permian, Carboniferous, Devonian, Silurian, Ordovician uye yeCambrian (dangwe).

YeCambrian Danho vakatanga vanenge mamiriyoni 570. Makore akapfuura (maererano zvimwe zvinyorwa, zvishoma apfuura). Ya nguva iyi, mamiriyoni 70. Years. The kutanga Danho chokuita shanduka kuputika munyika, umo makanga vamiririri dzakawanda zvikuru mapoka mhuka vanozivikanwa nhasi wokutanga.

Muganhu Precambrian uye yeCambrian akacherechedza ari pamatombo, apo pakarepo pane rakakura siyana mhuka zvisaririra pamwe chicherwa marangwanda. YeCambrian shanduka kuputika mumwe zvakavanzika nhoroondo nyika. Kuti aende nyore mumasero eukaryotic (more kunzwisisa) zvakatora makore maviri nehafu mamiriyoni. Kuburikidza Makore mamiriyoni 700. Kwaiva zvipuka zvine masero akawanda rokutanga. Uye. Nemakore anopfuura mamiriyoni 100 kubva nyika nyuchi incredible nemhuka dzakasiyana-siyana. Zvinofanira kucherechedzwa kuti kubva panguva iyoyo (makore anopfuura mamiriyoni 500) munyika vasina mhuka ane vangasimudzira itsva nemamiriro muviri.

Ordovician . Makore About mamiriyoni 500 apfuura akatanga uye dzakaguma -. Kusvika mamiriyoni 408 apfuura.

Vazhinji hwezasi hemisphere akatora Gondwana. Dzimwe nzvimbo huru munyika dzakanga dzichiitika munyika ine mapazi. Sea apo inogarwa mhuka dzakawanda, kwakasiyana chaizvo kubva vagere makungwa ose yeCambrian. Nyika yakanga kushanda kukodzera kuti upenyu - kwakanga kusina ivhu, hapana zvinomera, tsitsi inopisa zuva, kazhinji madutu uye kuputika kwemakomo.

By kuguma Ordovician pechikuva rakatanga kusarudzwa muna mumhenderekedzo yegungwa mumatope, decomposing nayo, notumwe nenzanga algae, mabhakitiriya. Saka, ivhu rukoko akaumba kusiri nyore.

Pakutanga hove Silurian akatora chimiro, pedyo yazvino chete. Pakazopera kwechikuva kutanga orogenic kwendangariro. Somugumisiro, havana akaumba yeCambrian, kuti Air makomo uye massifs muna Eastern Zimbabwe uye rwezasi Scotland.

Devonian Danho kukura Nyika kunoratidzwa mukuru njodzi panyika. Panguva iyoyo, paiva kurwisana pamusoro Zimbabwe, Europe uye North America. It akaumba mukondinendi guru Laurasia.

Carboniferous nguva (kabhoni faibha) inozivikanwa siyana mamiriro - change vakabva remakore remakore. Zvisinei, kazhinji, izvozvo (okunze) zvakasiyana nyorovera unozvidzora, subtropical uye mvura mapazi. Izvi akasika yakanaka ezvinhu kuti kupararira nomumachakwi uye masango zvinomera panyika.

Upenyu Paleozoic yaitonga yakaumbwa chaizvo kusvikira pakuguma rokupedzisira pechikuva.

Makore mamiriyoni 299. Kare, vakatanga yokupedzisira pavaipfuura Paleozoic. On pamuganhu Triassic nguva yakanga kupfuura zvikuru munhoroondo yepasi kuti mhando kutsakatika. Panguva ino, zvakanga akanyangarika vanenge 70% nyika uye 90% kubva zvomumvura zvipenyu. Saka akagumisa Paleozoic yaitonga.
