Mauna Kea volcano Magma

Summary:

All subaerial lavas at Mauna Kea Volcano, Hawaii, belong to the postshield stage of volcano construction. This stage formed as the magma supply rate from the mantle decreased and can be divided into two substages -- basaltic and hawaiitic. The objectives of this paper are to document the temporal geochemical trends that are defined by basaltic lavas that erupted during the late shield and postshield stages of Mauna Kea and to understand the processes that created the diversity of basalt compositions.
