dc.description.abstract"Mantle plumes produce basalts which provide fundamental information on the composition and history of the mantle. The Hawaiian plume is the classic example of a mantle plume and its basalts are unquestionably the best studied suite from any plume. The subaerially exposed lavas of Koolau Volcano belong to the Enriched Mantle1 endmember of ocean island basalts and they define a geochemical endmember among Hawaiian shield lavas in major and trace elements and in isotopes. Koolau lavas are important to an understanding of the origin and evolution of the Hawaiian plume and the mantle. In particular, Koolau lavas appear to provide the strongest evidence for deep mantle recycling of crust (sediments and basalt), although this interpretation remain controversial and is based on sampling only the uppermost veneer of the volcano. It is important to establish the longevity of the distinctive Koolau geochemical signature by sampling deeper and older lavas from the volcano. If there were basaltic and sedimentary components in the Hawaiian plume, were they restricted to the final stages of Koolau volcano´s growth? Scientific drilling will allow us to answer this question by obtaining lavas from subsurface of this enigmatic volcano."
