BackgroundSmall basaltic islets forming a volcanic neck rise only 8 m above sea level north of Genkaijima off the NW coast of Kyushu and are dated at about 1.13 +/- 0.12 million years (Nakano et al., 2001; Yokochi et al., 2005). Kurose is actually a small reef, formed from a highly eroded lava flow and columnar basalts (Yokochi et al., 2005). It is known for its ultramafic xenoliths, rich in olivine and pyroxene, which have been extensively studied geochemically for insight into the origin of these back-arc magmas (Senda et al., 2007).
