The pillow basalt is indeed formed under glacier and the unit on the top is most likely one of the many depositional facies one can find within the overlying hyaloclactite. They form during The initial phase of Surtsey's eruption was highly explosive, as the magma was quite wet, causing the rock to be blown apart by the boiling steam to form a tuff and cinder cone. pillow basalts, is formed at the contact with the glass rind. Pillow basalts have a structure consisting of overlapping pillow-shaped pods of basalt. These pillow structures are capped by several tens of metres of broken lava fragments from explosive shallow-water eruptions. Hydrothermal megaplumes are huge volumes of anomalously warm water that are located up to 1,000 metres above the sea floor and appear to be generated at mid-ocean ridges.
