Kīlauea summit photomicrographs of lava fluid inclusions and data

Detailed Description
Photomicrographs of fluid inclusions trapped inside olivine crystals present in rock samples collected on September 10th, 2023, during a summit eruption of Kīlauea (a-b, on left). Data from these fluid inclusions, collected over three days, reveal that the magmas resided in the shallow Halemaʻumaʻu (HMM) chamber before erupting; the deeper South Caldera magma chamber (SC) is also shown (c, on right).
