Abstract

We determined the major and trace element and Sr, Nd and Pb isotopic compositions of Quaternary magma from Futagoyama volcano, northeastern Kyushu, Japan. From the results, the most silisic magma keeps primary magma character, which is adakite generated by slab melting, and the less silisic magmas affected a contribution of crustal materials.
