Abstract

Chemical compositions of magmas together with available liquidus experimental data suggest that the primary basalt magmas both in the Japan Sea (BABB magma) and the NE Japanese volcanic front (VFB magma) were equilibrated with harzburgitic mantle materials at almost identical pressure and temperature conditions. The observation that the BABB magma is more depleted in Fe and some incompatible trace elements and more enriched in Al than the VFB magma then suggests that these magmas may have been derived from source mantle materials with different chemical compositions. -from Authors
