This data release contains selected results of whole-rock and glass analyses of lava samples collected during the 2018 eruption of Kilauea’s lower East Rift Zone (LERZ). Included are sampling-site information, eruptive vent/fissure, and sampling descriptions. During the 2018 LERZ eruption, the chemical analysis of lava samples was performed within hours of collection using an energy-dispersive X-ray fluorescence (ED-XRF) pressed-pellet methodology. The accuracy of this method was evaluated by analyzing a subset of samples using the more widely accepted wavelength dispersive X-ray fluorescence (WD-XRF) fused-bead methodology. WD-XRF analyses were performed both during and after the eruption at the Hamilton Analytical...
ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete.
