Summary:

The Hawaiian plume is long-lived, hot, and deep-seated, and offers an advantageous setting for unraveling the chemical and physical mantle structures because its tectonic setting is less complicated than other deep plumes. In an effort to gain further insight on the structure and dynamics of mantle plumes, the Hawaii Scientific Drilling Project (HSDP) was designed to recover a significant portion of the eruptive history of Mauna Kea, on the island of Hawaii, and to provide a coherent geophysical and geochemical data set with a semi-continuous time stratigraphic context. As a result, Sr, Nd, and Os isotopic measurements were made on 110 Mauna Kea lava and hyaloclastite samples from the drillcore retrieved from the second phase of the (HSDP-2) with the samples, methods of testing, and the results described in this document.
