• 1. [Article] Olivine Crystallization Depths within Kilauea's Lower East Rift Zone: The Use of Rehomogenized Melt Inclusions to Interpret Magma Transport, Storage, and Energetic Fountaining

  H2O and CO2 concentrations in olivine-hosted melt inclusions, assuming vapor saturation at the time of trapping, can be used to estimate crystallization depths for the olivine host. Estimating the true ...

  Citation × Citation Citation Abstract Copy Title: Olivine Crystallization Depths within Kilauea's Lower East Rift Zone: The Use of Rehomogenized Melt Inclusions to Interpret Magma Transport, Storage, and Energetic Fountaining Author: Tuohy, Robin Year: 2014 H2O and CO2 concentrations in olivine-hosted melt inclusions, assuming vapor saturation at the time of trapping, can be used to estimate crystallization depths for the olivine host. Estimating the true CO2 in melt inclusions is difficult, as much is lost to shrinkage bubbles, which form upon post-entrapment cooling and crystallization. Reheating olivine to temperatures above the melt inclusion trapping temperature and then quenching rapidly can restore CO2 to the glass because the CO2 in the bubble redissolves at high temperature. Previous work has established that olivine crystallization for the1959 Kilauea Iki eruption took place in the shallow summit reservoir, but crystallization depths have not been established for the rift extension of the eruption, at Kapoho. The new data presented here suggest that the most primitive Kilauea Iki component bypassed the summit reservoir for the east rift zone prior to the start of the eruption and was later erupted at Kapoho.
