- Summary:
- Thirteen samples of lavas from the island of Hawaii, including six from Kilauea, the 1919 lava of Mauna Loa, the Puu Anahulu trachyte, and a lava from Mauna Kea, show radium content, ranging from 0.75-1.09x10(super -6) ppm. Four samples of lavas from the older islands have radium contents ranging from 0.79-1.47x10(super -6) ppm. The average for all Hawaiian lavas is 0.96x10(super -6) ppm and is similar to the radium content of granites. The paper includes a complete major-oxide analysis from E.S. Shepherd of an olivine-rich block ejected from Halemaumau in 1924.
