Plume-type is a new branch of ophiolite classification introduced by Dilek and Fumes （2011; GSAB, 123,387-）. Its most typical example is the komatiite-basalt-gabbro- wehrlite assemblage that is exposed on the Gorgona Island off Colombia, South America and is interpreted as a part of the Caribbean large igneous province （LIP）. Analogous rock assemblage occur in the accretionary complexes in the circum-Pacific orogenic belts such as in Japan （Ishiwatari and Ichiyama, 2004; Int.
