the term ocean island basalt (also known as oib) is used to describe volcanic rock, usually basaltic in composition, erupted in the oceans away from tectonic plate boundaries. it is worth noting that while the name suggests that ocean island basalts are basaltic in composition, a wide range of compositions can be found at some ocean island basalt locations. for example, iceland is home to ocean island basalts that range in composition from tholeiitic basalt to rhyolite, and the intraplate volcano fernando de noronha also hosts ocean island basalt with diverse compositions, such as phonolites and trachytes. unlike mid-ocean ridge basalts (morbs), which erupt at spreading centers (divergent plate boundaries), and arc lavas, which erupt at subduction zones (convergent plate boundaries), ocean island basalts are the result of intraplate volcanism. however, some ocean island basalt locations coincide with plate boundaries like iceland, which sits on top of a mid-ocean ridge, and samoa, which is located near a subduction zone.
