Summary:

This paper studies major and trace element compositions of lavas from the entire 3098 m stratigraphic section from the phase II of the Hawaii Scientific Drilling Project. The top 245 m are lavas from Mauna Loa volcano and the bottom 2853 m are lavas from Mauna Kea volcano. Four magma types are recognized on the basis of MgO and Zr/Nb values. Type-1 is high SiO(sub 2) and Zr/Nb; type-2 is low SiO(sub 2) but high Zr/Nb; type -3 is low SiO(sub 2) and Zr/Nb; and type-4 is high SiO(sub 2) and low Zr/Nb.
