Some evidence from the Ratak Chain suggests that its volcanoes are Cretaceous in age and are related to the Rurutu-Arago Hotspot, which is currently located near Arago (also known as Tinomana) Seamount in the Southern Pacific Cook-Austral Islands. The Ralik Chain also formed during the Cretaceous, but it has remained sparsely sampled to date, and its origins are not yet firmly identified.
