Cov eon yog qhov dav tshaj plaws ntawm lub sijhawm geological. Lub ntiaj teb keeb kwm yog tus yam ntxwv ntawm plaub xyoo; nyob rau hauv kev txiav txim los ntawm tus hlob mus rau tus yau, cov no yog Hadeon, Archean, Proterozoic, thiab Phanerozoic.
Lub eon ntev npaum li cas hauv geology?
Hauv kev siv raug cai, eons yog qhov ntev tshaj plaws ntawm geological lub sijhawm (eras yog qhov thib ob ntev tshaj plaws). Peb eons tau lees paub: Phanerozoic Eon (tam sim no rov qab mus rau qhov pib ntawm Cambrian Lub Sijhawm), Proterozoic Eon , thiab Archean Eon .
