Subject:: Geology Mauna Kea volcano Xenoliths
Summary:: In this study, major element compositions of clinopyroxene, olivine and plagioclase grains and trace element compositions in clinopyroxene grains in xenoliths lacking orthopyroxene indicate a transitional magma parentage consistent with postshield magmas. Liquids calculated from the clinopyroxene in the xenoliths were compared to Mauna Kea shield lavas and to the postshield Hamakua and Laupahoehoe units.
