Tihooceansko-antarktički hrbat
Tihooceansko-antarktični hrbat je divergentna granica tektonskih ploča na dnu južnog Tihog okeana, koja razdvaja Tihooceansku ploču od Antarktičke. [1][2][3]Smatra se južnim nastavkom Istočnog tihooceanskog hrbata, južno od zone prijeloma Challenger[4] i proteže se do trojnog čvora Macquarie.[5][6][7] južno od Novog Zelanda.[8]
Louisvillski hrbat[uredi | uredi kôd]
Louisvillski hrbat je najduži podmorski planinski lanac u Tihom oceanu, prostire se u dužini od 4300 km u smjeru sjeverozapada od rasjedne zone Eltanin do podmorske planine Osmond kod Tonge. Smatra se da je nastao pomicanjem Tihooceanske ploče preko Louisvillske vruće točke iz koje izlazi magma.
