Rationale Emerging research in the geological and nuclear forensics fields demands increasing analytical precision of isotope ratio measurements with decreasing sample sizes. Here we demonstrate the capability of a newly developed amplification technology to make precise neodymium (Nd) isotopic measurements on 100‐pg standard loads. Methods The reference materials were analyzed as NdO+ to increase the ionization efficiency of the small analyte loads. The Nd isotopic measurements were made using an IsotopX Isoprobe‐T thermal ionization mass spectrometer upgraded with the ATONA™ amplifier system. The ATONA™ amplifier system uses capacitance‐based amplification as opposed to traditional impedance‐based amplification. Results The long‐term gains of the ATONA™ amplifiers are shown to have less than 1 ppm variability. Repeat measurements of the JNdi‐1 reference material demonstrate the ability of the ATONA™ amplification technology to make measurements of 143Nd/144Nd ratios with 23 ppm external reproducibility on 100‐pg loads. The effect of increasing integration time on analytical reproducibility is also displayed as increasing integration time from 10 to 30 s reduced the external measurement uncertainty from 37 to 23 ppm. Conclusions These measurements represent an improvement of more than a factor of 3 in external measurement reproducibility relative to previously published 143Nd/144Nd measurements of 100‐pg loads. This new technology will allow for the measurement of smaller samples for precise isotope ratios and open new avenues of research in the geological and nuclear forensic communities.

“…Nonetheless, all Sr and Nd isotopic data, including melt inclusions that have unacceptably low sample/blank ratios, are reported in Tables S7 and S8. Blank corrections were made using the laboratory blank 87 Sr/ 86 Sr and 143 Nd/ 144 Nd ratios previously determined for the Sr and Nd chemistry at VU (Koorneef et al, 2015;Knaf et al, 2017); the total procedural blank isotopic ratio used for correction is 0.711120 ± 0.000050 (n =3) for 87 Sr/ 86 Sr and 0.511856 ± 0.000090 (n = 3) for 143 Nd/ 144 Nd.…”

ABSTRACTGeochemical investigations of mantle heterogeneity as sampled by ocean island basalts (OIB) have long relied on isotopic analyses of whole rock lavas. However, recent work has shown that significant isotopic disequilibrium can exist between the phases (groundmass and phenocrysts) of a single OIB lava. In this study, we target individual olivine hosted melt inclusions from two lavas-one Samoan and one Hawaiian-with melt inclusion 87 Sr/ 86 Sr heterogeneity previously observed using laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS). We report 87 Sr/ 86 Sr and 143 Nd/ 144 Nd in individual melt inclusions using thermal ionization mass spectrometry (TIMS). In melt inclusions from Samoan sample AVON3-71-2, we find highly heterogeneous (935 ppm) 87 Sr/ 86 Sr (0.705193 -0.705853, N=6), consistent with previously identified 87 Sr/ 86 Sr heterogeneity (~2030 ppm) by laser ablation multicollector ICP-MS (0.70459 -0.70602, N=12). In contrast, we find very little (251 ppm) 87 Sr/ 86 Sr Cabral et al., 2014;Rose-Koga et al., 2012 and Sr (Jackson and Hart, 2006;Harlou et al., 2009;Sobolev et al., 2011) isotopic compositions that span much of the variability observed in oceanic lavas globally. Despite their volumetrically minor contribution to the whole rock lava, the isotopic diversity preserved in melt inclusions provides important information about mantle melting and the processes that operate in magma chambers. The origin of the chemical and isotopic diversity in melt inclusions remains the source of debate, but has most often been attributed to either assimilation of oceanic crust or mixing of isotopically heterogeneous pristine mantle melts (e.Only a handful of studies have examined Sr isotopic compositions of olivine hosted melt inclusions from ocean island basalt (OIB) lavas. Jackson and Hart (2006) were the first to target individual olivine-hosted melt inclusions for Sr isotopic analysis, utilizing laser ablation multicollector inductively coupled plasma mass spectrometry (ICP-MS) to analyze melt inclusions from Samoan picrites. Jackson and Hart (2006) found 87 Sr/ 86 Sr variability within olivine-hosted melt inclusions from a single basalt as large as 3400 ppm, which is 13% of the total range observed in the lavas from the ocean basins (i.e., 0.7021 [Schilling et al., 1994;Fontignie and Schilling, 1996] to 0.7205 [Jackson et al., 2007]). This result was reinforced by the work of ...
