Pasi rine makore mangani?
Context:Chiyero chenguva ye geology inzira yekumirira nguva yakadzika yakavakirwa pazviitiko zvakaitika munhoroondo yePasi, nguva yenguva ingangoita 4.54 ± 0.05 Ga (4.54 mabhiriyoni emakore). Inoronga matanda, uye gare gare nguva, mukutevedzana kwenguva, kupfurikidza nokucherechedza chinjo dzinokosha mu stratigraphy dzinowirirana nezviitiko zvikuru zvegeological kana kuti paleontological. Somuenzaniso, kuparara kweCretaceous<unk>Paleogene, kunoratidza muganhu wepasi wePaleogene System/Period uye nokudaro muganhu pakati peCretaceous nePaleogene Systems/Periods. Nokuda kwezvikamu zvakatangira nguva yeCryogenian, tsanangudzo dzomuganhu dzomuganhu (Global Standard Stratigraphic Ages, GSSAs) dzinoshandiswa kugovera nguva ye geologic. Zvikarakadzo zvakaitwa kuti izvi zvikamu zviwiriraniswe zviri nani nechinyorwa chamatombo.
Pasi rine makore anenge mabhiriyoni 4,54 okuberekwa.
