- Summary:
- Isotopic and incompatible element abundance ratios in the Haleakala postshield basalts changed systematically with time, resulting the evolved Haleakala lavas formed from a range of parental compositions. Although alkalic basalt and hawaiite are the dominant lavas of the postshield stages of both Haleakala and Mauna Kea volcanoes, there are important differences, which indicate that the evolved lavas at Haleakala formed at lower pressures. In addition, basalts are intercalated with hawaiites at Haleakala whereas basalts and hawaiites are separated by a sharp boundary at Mauna Kea.
