I-Meghalai century - igama elisemthethweni lekhulu lama-21
I-International Commission on Stratigraphy yathatha isinqumo esivumelana futhi yavuma negama lesikhathi esiphila kuso. Isikhathi esiqale eminyakeni engama-4200 edlule futhi esaqhubeka kuze kube namuhla sibizwa ngekhulu le-Meghalai.
Le ncazelo iyatholakala kuwebhusayithi esemthethweni yenhlangano.
Ukuqomisana komlando weplanethi kusethwe esikalini se-geochronological. Futhi isilinganiselo sisuselwa ku-stratigraphy. Akucaci kabani kuye - ekushintshanisweni kwengqimba yamatshe. Yize imigomo iyamangaza phakathi kwama-uninitiated (futhi lokhu kungama-99,9% wabantu bonke beplanethi enguMhlaba), kepha phakathi kososayensi, konke kunengqondo futhi kunengqondo.
Iminyaka ye-Meghalai
Uma ufunda umlando, khona-ke ubuntu buhlala esikhathini se-Holocene. Ngokuqondile, esikhathini se-Cenozoic se-Quaternary. Ukuze bangazihlanganisi nesigama, ososayensi batusa ukuthi umfundi akhumbule kuphela igama lekhulu leminyaka futhi azi ukuthi laqhamuka ngasiphi isikhathi. Ukukala kuqala ngesomiso esikhulu, esathatha amakhulu amabili eminyaka.
Umbono ngaphandle kokwenza ufile, inqobo nje uma kungekho bufakazi - hhayi ukholo!
Igama "Meghalai Century" linikezwe ukuhlonipha iMeghalaya Cave, ese Indiana, USA. AmaMelika abeka isikhathi sokuqala kwesomiso kusuka edwaleni ledwala. Abaphenyi e-Asia naseYurophu banemibuzo emakhulu kososayensi base-US mayelana ne-stratigraphy kanye nemihume yaseNdiya. Kodwa-ke, abamele i-US abasheshi ukwaba imiphumela yabo. Ukuchazwa kwe- "Meghalai Age" kwavela eminyakeni eyisithupha edlule, futhi kusasenabo ubufakazi. Ngakho-ke, okwamanje, kuzofanela saneliswe imibono yabachwepheshe kanye nomcabango.
