“…Instrumental mass bias for Hf was corrected based on the measured 179 Hf/ 177 Hf and its natural ratio (0.7325; Blichert‐Toft et al ), using an exponential law. Forty‐five analyses of R10 yielded a mean 176 Hf/ 177 Hf value of 0.282169 ± 0.000211 (2 s ), in agreement with the results reported by Luvizotto et al () and Li et al () (0.282178 ± 0.000012 and 0.282157 ± 0.000204, respectively). Thirty analyses of the Penglai zircon reference material yielded a mean 176 Hf/ 177 Hf value of 0.282915 ± 0.000037 (2 s ), in agreement with the recommended value (0.282906 ± 0.000010) reported by Li et al ().…”

“…At this stage, only RMJG, R10, JDX and R19 have been analysed for Hf isotope determination by the solution MC‐ICP‐MS method. Using LA‐MC‐ICP‐MS, Li et al () measured Hf isotopes in PCA‐S207 and Sugluk‐4. All these measured rutiles display homogeneous Hf isotopic ratios when the analytical error is considered.…”

“…Therefore, the mass bias factors for Yb and Lu were assumed to be the same as that for Hf. The very low Yb and Lu contents make 176 Hf/ 177 Hf insensitive to the mass bias factors for Yb and Lu (Li et al ). Instrumental mass bias for Hf was corrected based on the measured 179 Hf/ 177 Hf and its natural ratio (0.7325; Blichert‐Toft et al ), using an exponential law.…”

“…Rare magmatic rocks (e.g., anorthosites, pegmatites and quartz veins) also contain this mineral. Rutile attracts much attention from the Earth Science community (Meinhold , Triebold et al , Zack and Kooijman ) due to its: (a) significant U content, low common Pb content and resistance to weathering, which makes rutile an important geochronometer (Mezger et al , Luvizotto et al , Kooijman et al , Li et al , Zack et al , Xia et al , Axelsson et al ); (b) temperature‐sensitive Zr content, which allows rutile to be used as a geothermometer in metamorphic rocks (Zack et al , Watson et al , Zack and Luvizottow , Tomkins et al , Zheng et al , Ewing et al , Pape et al ); (c) Cr‐Nb‐Zr contents, which provide an indication of the source lithology (Zack et al , Stendal et al , Meinhold et al , Triebold et al ); and (d) moderate Hf content (~ 50 µg g −1 ) that allows Hf isotopic measurement of rutile by LA‐MC‐ICP‐MS to trace heterogeneous sources (Ewing et al , , Li et al ).…”

Matrix‐matched reference materials are necessary for accurate microbeam U‐Pb dating and Hf isotopic determination. This study introduces the RMJG rutile as a new potential reference material, which was separated from Palaeoproterozoic pelitic granulites collected in Hebei Province, China. LA‐ICP‐MS measurements indicate the RMJG rutile has extremely low Th (< 0.003 ± 0.01 µg g−1) and common Pb contents, but high Hf (102 ± 34 µg g−1), U (61 ± 11 µg g−1), and radiogenic Pb (~ 20 µg g−1) contents. Moreover, the rutile yields relatively constant U‐Pb ages and Hf isotopic data. The LA‐ICP‐MS analyses suggest that this rutile has a concordant U‐Pb age with a statistical mean 206Pb/238U and 207Pb/235U ages of 1749.9 ± 32.1 Ma and 1750.0 ± 26.4 Ma, respectively (2s), which are statistically indistinguishable from its ID‐TIMS ages (1750.6 ± 8.4 and 1750.1 ± 4.7 Ma). Precise determination of the 176Hf/177Hf ratio by MC‐ICP‐MS in solution mode (0.281652 ± 0.000006) is in good agreement with the statistical mean of the LA‐MC‐ICP‐MS measurements (0.28166 ± 0.00018). Therefore, the limited variations of RMJG U‐Pb age and Hf isotopic composition together with its extremely low common Pb and high Hf, U and Pb contents make it an ideal calibration and monitor reference material for LA‐ICP‐MS measurements.

“…, Li et al . ), there are relatively few established titanite reference materials (e.g., Khan, BLR‐1, OLT1 for U‐Pb dating and MKED1 for U‐Pb and Sm‐Nd isotope microanalysis), and with the advent of high‐throughput in situ analytical methods, demand for titanite geochronology reference materials is outstripping supply. Moreover, the growing application of in situ titanite Sm‐Nd isotope measurement by LA‐(MC)‐ICP‐MS has created a need for a range of homogeneous Sm‐Nd reference materials.…”

Titanite is a common accessory mineral that preferentially incorporates considerable amounts of U and light rare earth elements in its structure, making it a versatile mineral for in situ U‐Pb dating and Sm‐Nd isotopic measurement. Here, we present in situ U‐Pb ages and Sm‐Nd isotope measurement results for four well‐known titanite reference materials (Khan, BLR‐1, OLT1 and MKED1) and eight titanite crystals that could be considered potential reference material candidates (Ontario, YQ‐82, T3, T4, TLS‐36, NW‐IOA, Pakistan and C253), with ages ranging from ~ 20 Ma to ~ 1840 Ma. Results indicate that BLR‐1, OLT1, Ontario, MKED1 and T3 titanite have relatively homogeneous Sm‐Nd isotopes and low common Pb and thus can serve as primary reference materials for U‐Pb and Sm‐Nd microanalysis. YQ‐82 and T4 titanite can be used as secondary reference materials for in situ U‐Pb analysis because of their low common Pb. However, internal structures and mineral inclusions in YQ‐82 will require careful selection of suitable target domains. Pakistan titanite is almost concordant with an age of 21 Ma and can be used as a reference material when dating Cenozoic titanite samples.
