Major-element compositional data and thermal data for drill core from Kīlauea Iki lava lake, plus analyses of glasses from scoria of the 1959 summit eruption of Kīlauea Volcano, Hawaii

Nickel Isotope Fractionation During Magmatic Differentiation

“… δ 60/58 Ni, TFeO (total Fe expressed as FeO), and Cu versus MgO for samples from Kīlauea Iki (KI) lava lake (orange circles; left panel), and Kamchatka arc lavas (yellow diamonds; right panel). TFeO data of KI lavas are compiled from Helz (2020), Helz et al. (1994), Helz and Taggart (2010), and Murata and Richter (1966), with bulk‐rock analyses shown in gray (Helz & Taggart, 2010; Helz et al., 1994; Murata & Richter, 1966) and electron microprobe analyses of glasses shown in blank (Helz, 2020).…”

“…The KI lavas have been extensively studied as a natural laboratory of basalt differentiation (Badullovich et al., 2017; H. Chen et al., 2013; X. Ding et al., 2020; Helz, 1987, 2020; Helz & Taggart, 2010, 2012; Helz et al., 1994; Johnson et al., 2019; Shen et al., 2020; Teng et al., 2008; Zhang et al., 2018; X. Zhao et al., 2020). Samples with MgO < 11 wt.% experienced fractional crystallization of olivine, augite, feldspar, and then Fe‐Ti oxides (Helz, 1987; Teng et al., 2008).…”

“…Samples with low MgO contents (less than 6 wt.%) occur in forms of segregation vein and ooze (collected in the molten state in the hole and later also cored), representing the last stage of magmatic fractionation (Helz, 1987;Wright et al, 1976). Electron microprobe analyses of the glasses in the most evolved KI lavas (<5 wt.% MgO) show decreased TFeO, which is a result of magnetite crystallization (Helz, 1987(Helz, , 2020. Those glasses also contain Cu-rich sulfide phases, leading to strong Cu depletion in the glasses as determined by in situ LA-ICP-MS (Greaney et al, 2017).…”
