Summary:

In 1993, the Hawaii Scientific Drilling Project successfully cored over 1000 meters of basalt that included 280 meters of lava from Mauna Loa and 800 meters of basalt from the flows of Mauna Kea. Of these cored basalts, thirty-one basalts that were collected from Mauna Kea were analyzed by inductively coupled plasma mass spectrometry for rare earth element (REE) concentrations. This paper focuses on the systematic variations in the REE of the sub-section of these Mauna Kea basalts and the ability of various models of melt generation to reproduce the REE patterns of liquids.
