“…Tin could occur in stoichiometrically Sn-bearing and stoichiometrically Sn-free sulfides, and Sn-bearing sulfides like kesterite could have implications for exploration at the porphyry–epithermal environment . As shown in Figure , the Sn-bearing sulfide precipitates from the coexisting fluid would enrich in lighter Sn isotopes.…”

“…Such processes do not need the redox reaction of Sn in hydrothermal fluids, i.e., Sn(IV) species are predominant during the precipitation of hydrothermal cassiterite, which is also indicated by our transport-precipitation model built with Sn isotope fractionation during the hydrothermal ore-forming processes. 30 Tin could occur in stoichiometrically Sn-bearing and stoichiometrically Sn-free sulfides, 110 and Sn-bearing sulfides like kesterite could have implications for exploration at the porphyry−epithermal environment. 111 As shown in Figure 5, the Sn-bearing sulfide precipitates from the coexisting fluid would enrich in lighter Sn isotopes.…”

Quantifying equilibrium Sn isotope fractionation among Sn-bearing minerals is fundamental for understanding the partitioning of Sn isotopes during various geological and cosmochemical processes. In this study, we used first-principles calculations to evaluate equilibrium Sn isotope fractionations among 13 Sn-bearing minerals. The Sn isotope reduced partition function ratios (RPFRs or β factors) calculated with the state-of-the-art r2SCAN functional decrease in the order of brannockite > eakerite > megawite > cassiterite > pirquitasite > kesterite > stannite > berndtite-2T ≈ hydroromarchite > romarchite > ottemannite > herzenbergite > native tin. At high temperatures, the variation range can still be large. The 1000 ln122/116 β values show a linear relationship with the average Sn force constants in minerals. The results indicate that under equilibrium, the preference of heavy Sn isotope partitioning decreases in the order of Sn(IV) minerals > Sn(II) minerals > native tin. Stannic silicates are enriched in heavy Sn isotopes among all of the minerals, and oxides are enriched in heavy Sn isotopes relative to sulfides in addition to the effect of the oxidation state of Sn. The RPFRs for hydrothermal Sn species are between those of oxide and sulfide minerals at the corresponding oxidation states. These results provide a data set of equilibrium Sn isotope fractionation factors, which indicates that the changes in the coordination environment and in the oxidation state can have similar effects on equilibrium Sn isotope fractionation. This could be important in interpreting natural Sn isotope variabilities.

“…[1][2][3] Laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) has been successfully employed for the microanalysis of sulde minerals, yielding successful results. [4][5][6] Due to their unique physical and chemical properties, sulde minerals show different laser ablation behaviors from conventional geological samples, such as silicate glass. The most intuitive phenomenon is related to the melting, vapor redeposition, and heat-affected zone around the ablation crater caused by a laser thermal effect, which is the main factor limiting the precision and accuracy of sulde minerals analysis.…”

“…Due to its high sensitivity, low detection limit, and broad linear range, inductively coupled plasma mass spectrometry (ICP-MS) has become one of the most competitive and promising methods for trace and ultratrace REE analysis in geological materials [7,[23][24][25] and is widely used in trace element testing compared to other analytical techniques like neutron activation analysis [26][27][28][29][30], X-ray fluorescence spectrometry [31][32][33], laser-induced breakdown spectrometry [34][35][36][37], atomic absorption spectroscopy [38][39][40][41], and inductively coupled plasma atomic emission spectrometry [42][43][44][45]. There have been many reports of concentrations of trace elements in coals that were successfully determined by ICP-MS [46][47][48][49][50][51][52].…”

Europium (Eu) in coal and sedimentary rocks has important mineral resource potential as well as being a crucial parameter in geochemical studies that can represent changes in the depositional environment during coal deposition and identify the depositional source region. Therefore, it is essential to realize the precise measurement of Eu in coal as this could be a useful parameter for paleoenvironmental reconstruction studies and the exploration of mineral resources. During inductively coupled plasma mass spectrometry (ICP-MS) analysis, polyatomic ions of Ba may interfere with Eu, causing the observed value to be higher than the actual value. This paper develops a new approach for Eu determination by using a high-resolution inductively coupled plasma mass spectrometry (HR-ICP-MS). The mass spectral interference and correction of Eu in the coal and sedimentary rock samples at low, medium, and high resolutions were investigated. The results showed that in the high-resolution mode (resolution = 10,000 amu), the interference of polyatomic ions of Ba could be distinguished from Eu; hence, Eu was determined under this circumstance. Under the optimal experimental circumstances, the detection limit was 0.006 μg/mL, the relative standard deviation was 0.80%–1.22%, and the linear correlation coefficient of the standard curve was over 0.9999. The recoveries of the 103Rh internal standard solution ranged from 94.41% to 100.10%. This method was verified using standard reference materials and selected samples, which demonstrated its high sensitivity, accuracy, and reliability, and a low detection limit, making it appropriate for detecting Eu in samples of coal and sedimentary rocks.
