“…After 242 Kilauea Iki samples had been analyzed for major elements (Helz and others, 1994;Helz and Taggart, 2010), the present subset of 84 was submitted for trace-element analysis. Samples for trace-element analysis were chosen to represent all rock types found in the lake and the full range of major-element compositional variation observed.…”

“…The results of studies based on the 1967-1981 cores were reported in Helz (1980;1987a, b), Helz and Thornber (1987), Helz and others (1989), Helz and others (1994), and Barth and others (1994). Helz (2009) was the first paper to make use of the major-element analytical results for the 1988 core, which were presented in Helz and Taggart (2010).…”

We quantify the behavior of Cu, Ga, Ge, As, Mo, Ag, Cd, In, Sn, Sb, W, Tl, Pb, and Bi during the differentiation of a picritic magma in the Kilauea Iki lava lake, Hawaii, using whole rock and glass differentiation trends, as well as partition coefficients in Cu-rich sulfide blebs and minerals. Such data allow us to constrain the partitioning behavior of these elements between sulfide and silicate melts, as well as the chalcophile element characteristics of the mantle source of the Kilauea lavas. Nearly all of the elements are generally incompatible on a whole-rock scale, with concentrations increasing exponentially below $6 wt% MgO. However, in-situ laser ablation data reveal that Cu, Ag, Bi, Cd, In, Pb, and Sn are chalcophile; As, Ge, Sb, and Tl are weakly chalcophile to lithophile; and Mo, Ga, and W are lithophile. The average D sulfide/silicate melt values are:

In order to investigate possible Ca isotopic fractionation during basaltic magma differentiation, we measured Ca isotopic compositions of lavas recovered from Kilauea Iki lava lake at Hawaii. This set of lavas record the whole crystal fractionation history of basaltic magma, ranging from olivine accumulation/fractionation to multiple phase crystallization, including plagioclase and clinopyroxene. Our results show no detectable Ca isotopic variation in all measured Kilauea lavas at a precision of ±0.07‰ for 44Ca/40Ca (δ44/40Ca = 0.80 ± 0.08, 2 SD, n = 19). Using such observation and published intermineral Ca isotopic fractionation factors, a Monte Carlo approach is used to estimate the mineral‐melt 44Ca/40Ca fractionation factors. We found that Ca isotopic fractionation between clinopyroxene and basaltic melt is small, with Δ44/40Cacpx‐melt = 0.04 ± 0.03 at 1200 °C. To the best of our knowledge, this is the first estimated mineral‐melt Ca isotopic fractionation factor reported. We use this estimated Δ44/40Cacpx‐melt and intermineral Ca isotopic fractionation factors to investigate Ca isotopic effects during mantle partial melting under 1–2 GPa. Our simulations show that the largest 44Ca/40Ca effect, up to +0.3‰, is achieved in large degree melting residues during fractional and dynamic melting. In contrast, partial melts show negligible 44Ca/40Ca isotopic effect, <0.07‰.
