The deepest and oldest volcanic rocks appear to be fore-arc basalt (FAB), a distinctive type of volcanic rock akin to mid-ocean-ridge basalt (MORB) that has been recovered during dredging and submersible sampling of the IBM fore arc (Reagan et al., 2010), as well as by drilling at Sites U1440 and U1441. More strongly subduction-affected magnesian lavas called boninites also erupted in the IBM nascent arc. These lavas are named after the type section on the island of Chichijima in the Bonin Islands (Umino, 1986) and were also drilled at Site U1439. | Publication Type: | Book Chapter | Grant Details: | ARC/LE140100047 | Source of Publication: | Proceedings of the International Ocean Discovery Program, v.352, p. 1-43 | Publisher: | International Ocean Discovery Program | Place of Publication: | Texas, United States of America | Fields of Research (FoR) 2008: | 040304 Igneous and Metamorphic Petrology 040202 Inorganic Geochemistry |
