Baleyoarkeyaan (/ˌpeɪlioʊɑːrˈkiːən/), oo sidoo kale loo higaadiyay Palaeoarchaean (hore loogu yiqiin hore Arkeyaan), waa xilli juqraafiyeed gudaha eonka Arkeyaan. Magaca waxa uu ka yimid Giriiga "Palaios" qadiimiga ah. Waxay socotaa muddada 3,600 ilaa 3,200  milyan oo sano kahor. Xilliga waxa loo qeexaa si taariikhi ah lamana tixraacin heer gaar ah oo qaybta dhagaxa ah ee Dhulka.  Caddaynta ugu horraysa ee la xaqiijiyey ee noloshu waxay ka timid wakhtigan, iyo Faalbara, oo ah mid ka mid ah qaaradaha sare ee ugu horreeya Dunida, ayaa laga yaabaa inay samaysmeen muddadan.Lepot, Kevin (2020).
