Abstract
Mauna Kea Volcano, on the Island of Hawaii, is capped by lavas of alkalic and transitional basalt (Hamakua Volcanics) erupted between approximately 250-200 and 70-65 ka and hawaiite, mugearite, and benmoreite (Laupahoehoe Volcanics) erupted between approximately 65 and 4 ka. These lavas, which form the entire subaerial surface of the volcano, issued from numerous scattered vents and are intercalated on the upper slopes with glacial deposits. The lavas record diminishing magma-supply rate and degree of partial melting from the shield stage through the postshield stage. Much of the compositional variation apparently reflects fractionation of basaltic magma in reservoirs within and beneath the volcano.
