Machida, S. and Ishii, T. (2003). Backarc volcanism along the en echelon seamounts: The Enpo seamount chain in the northern Izu-Ogasawara arc. Geochemistry Geophysics Geosystems 4. doi: 10.1029/2003GC000554. issn: 1525-2027.

We report results of detailed petrological analyses of volcanic rocks from the Enpo seamount chain that reveal the characteristics of volcanism in a backarc en echelon seamount chain in an oceanic island arc setting. We identified two types volcanic rock suites in the Enpo seamount chain based on bulk rock trace element chemistry and compositions of chrome spinels included in olivine phenocrysts of primitive basalts. More Enriched Suites (MES) have enriched HFSE compositions (such as Nb, Ta), higher Nb/Zr values, and low Cr
