Strontium isotope ratios of lavas from Kīlauea Volcano, Hawaiʻi

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: January 27, 2026 | Last Modified: 2020-09-29T00:00:00Z
Strontium isotope ratios of historical Kīlauea summit and rift lavas were analyzed by thermal ionization mass spectrometry (TIMS) at the Southwest Isotope Research Laboratories of the U.S. Geological Survey (USGS) in Denver. There were 151 analyses of 49 samples obtained from the field, the collections of the USGS Hawaiian Volcano Observatory (HVO), and the Smithsonian Institution. Data for associated reference materials are described in the process steps . The Sr isotope ratios may be used to test models for the volcano’s magmatic plumbing system.
