“…Garnet standards WS-20 and GRT-1 were used to monitor the garnet age determinations. They yielded Tera-Wasserburg concordia intercept ages of 1152.2 ± 5.8 and 137.0 ± 2.3 Ma, respectively, which are the same as the published ages within the analytical uncertainty (Li et al, 2022;Zhang et al, 2019). The raw data reduction was performed off-line using Iolite 4.0 software (Petrus and Kamber, 2012).…”

Numerous skarn-type Sn deposits have been identified in the Nanling Range (South China), of which the Shizhuyuan W-Sn-Bi-Mo, Xianghualing Sn, Jinchuantang Sn-Bi, and Hehuaping Sn deposits are the largest. The Xianghualing deposit, which is the focus of this study, hosts a resource of 0.17 Mt Sn grading 0.93-1.39 wt% SnO 2 .Whether the distal skarn-type mineralization and the cassiterite-sulfide vein-type orebody in the Xianghualing district are genetically related to the Laiziling granitic pluton, which produced the proximal skarn-type Sn mineralization, however, is still unknown. The Xianghualing Sn mineralization occurs exclusively as cassiterite and has been subdivided into four ore-types: (1) lenticular proximal skarn ore (Cst I) containing the mineral assemblage cassiterite-pyrrhotite-chalcopyrite-actinolitewollastonite; (2) layered distal skarn ore (Cst II) containing the mineral assemblage cassiterite-pyrrhotite-chalcopyrite-actinolite; (3) vein cassiterite-sulfide ore (Cst III) distal from the skarn and associated granite containing the mineral assemblage cassiterite-arsenopyrite-pyrrhotite-muscovite-fluorite; and (4) veinlet Sn-Pb-Zn ore (Cst IV) distal from the skarn and associated granite containing the mineral assemblage cassiterite-galena-sphalerite-topaz-quartz. Here, we report the results of in situ laser ablation inductively coupled plasma mass spectrometric (LA-ICP-MS) U-Pb age determinations for garnet from the Xianghualing skarn and the above four types of cassiterite. Our age determinations indicate that there were two independent magmatic-hydrothermal events at ~160 and 156~150 Ma, both of which led to Sn mineralization. The first Sn mineralization event at ~160 Ma (Cst IV U-Pb ages of This is the peer-reviewed, final accepted version for American Mineralogist, published by the Mineralogical Society of America.The published version is subject to change.

“…The time-dependent dris of U-Pb isotopic ratios were corrected with a standard-sample bracketing procedure, i.e., NIST612/NIST614 + 291 500 + 2 RMJG + 10-15 samples + 2 RMJG + 291 500 + NIST612/NIST614. As there were no matrix-matched primary standards for ilmenite minerals, several known RMs, i.e., zircon 91500, rutile RMJG, 37 and wolframite YGX (Febearing member) 30 and garnet PL-57 (Fe-and Ti-bearing member), 38 were chosen to calibrate the unknowns in experiment 1. In experiments 2 and 3, only zircon 91500 and rutile RMJG were analyzed as primary standards for comparison.…”

“…43 As the most homogeneous and widely distributed zircon RM in the world, 91500 has a concordant U-Pb age The PL57 garnet occurs in the calcite ijolite in the Prairie Lake alkaline complex, Canada, and has 6.5-15.0 wt% TiO 2 , 17.1-21.3 wt% Fe 2 O 3 , and 27-76 ppm U; it yielded a concordant ID-TIMS U-Pb age of 1156.2 ± 1.2 Ma. 38 Rutile RMJG, collected from Palaeoproterozoic pelitic granulites in Hebei Province, China, has low Th, high U, and radiogenic Pb contents of <0.003, ∼61, and ∼20 ppm, respectively. This rutile yields a weighted mean 207 38…”
