Tin stable isotopes in magmatic-affected coal deposits: Insights in the geochemical behavior of tin

Sn Isotopic Values in Ten Geological Reference Materials by Double‐Spike MC‐ICP‐MS

“…Tin, a moderately siderophile, chalcophile and volatile element, has ten naturally occurring stable isotopes. The isotopic signature of Sn has been used to investigate the magmatic sources, the differentiation of terrestrial rocks and meteorites (Badullovich et al 2017, Wang et al 2018, Yao et al 2018, Qu et al 2020, and the formation and differentiation of celestial bodies in the early history of the Solar System (Wang et al 2018, Wang et al 2019. Tin isotopic analysis has also been employed to determine the provenance of raw materials in ancient bronze and identify fakes consisting of bronze in archaeology (Haustein et al 2010, Nickel et al 2012, Yamazaki et al 2014, Brügmann et al 2017, Schulze et al 2017, Berger et al 2018, Mason et al 2020.…”

High-precision double-spike Sn isotope analysis of geological materials by MC-ICP-MS

“…High-precision Sn isotope analysis, with or without a double spike, could be compromised by the isobaric and molecular interference of Te, Cd, In, and Mo 41 (Table S1 †), thus these elements need to be effectively separated from Sn during the column chemistry that is aimed at purifying Sn from the rock matrix. In the literature, different resins, including TBP, AG MP-1, and AG1-X8, had been used for the purication of Sn; 25,30,41,43,44,57,58 more recently, several studies have utilized TRU resin for the Sn separation procedure. 1,30,[41][42][43]48,59 The elution curves of different elements for the two different column procedures are shown in Fig.…”

“…For comparison, AG1-X8 is an anion exchange resin that can separate Sn from a number of matrix elements, including Fe, Mg, Mo, In, and Cd. 30,43,44 Various elements, including In and Pb, could be eluted off the column before the Sn cut, but the full separation of Sn, Cd, and Zn cannot be achieved. In this step, the recovery of Sn was 99.1 ± 2.5% (2SD, N = 2).…”

“…Due to the "magic number" closed proton shell in its nucleus, 25 Sn has ten stable isotopes with the largest mass variations in the periodic table. [26][27][28] Stable Sn isotopes are a powerful tool for studying the behavior of Sn in various processes, 5,8,9,[29][30][31] as well as tracking the provenance of Sn in various natural samples and archaeological artifacts, [32][33][34][35] thus there has been a long interest in the Sn isotope variability of natural and articial Sn-bearing samples. Early studies used thermal ionization mass spectrometry (TIMS) for Sn isotope measurements, [36][37][38] however, the high ionization potential (7.3 eV) of Sn prevents efficient and stable ionization of Sn.…”
