“…In recent years, geological samples have been often prepared by acid solution methods for REE and isotope measurements under an enclosed system at high temperature for a long duration [25][26][27][28] . For the scheelite, samples are often dissolved in hydrothermal bombs using a mixture of HF and HNO 3 with a ratio of 9/2 or HF-HNO 3 -HCl-HClO 4 and kept at 150℃ for at least three days.…”

The scheelite with large size and euhedral shape from Xuebaoding, Sichuan Province is an ideal mineral to study REE patterns and Sm-Nd dating of non-gold deposits. The scheelite has diameters of 1-10 cm and colors of pale beige to deep orange. Most of these scheelites occur in association with beryl, cassiterite and muscovite. The rare earth elements indicate that scheelite samples from Xuebaoding W-Sn-Be deposits contain high concentrations of rare earth elements with total ΣREE+Y contents in the range of 369-1725 μg·g −1 and nearly all of these scheelite samples are enriched in LREE and depleted in HREE and have negative Eu anomalies. The REE patterns of the scheelites are similar to those of A-type granite with obvious tetrad effect, similar to that of type II scheelites. Based on reported fluid inclusion studies, the mineralizing-fluid of the Xuebaoding W-Sn-Be deposit indicates low Na activity. The REE patterns of the scheelite are probably controlled by partition coefficient in hydrothermal fluid. In the 147 Sm/ 144 Nd-143 Nd/ 144 Nd diagram, the scheelites show a linear array corresponding to an isochron age of 182.0±9.2 Ma (MSWD = 0.52). The Sm-Nd age represents the formation age of the scheelite and can indicate that the W, Sn and Be mineralization at Xuebaoding took place in the Early Yanshanian. The Sm-Nd dating result is important for the study of the multi-metal resources in western Sichuan Province.scheelites, REE, Sm-Nd isotope dating, Xuebaoding deposit, Sichuan Province Since Fryer et al. used the Sm-Nd isotope method to date the age of hydrothermal deposits [1] , this geochronometer has been used to date metallic deposits using a few hydrothermal minerals such as fluorite, wolframite, tourmaline and calcite [2][3][4][5][6][7][8][9][10][11][12][13][14] . Scheelite is one of the Cabearing minerals and rare earth elements (REE) are incorporated into the Ca 2+ structural sites of the scheelite crystal structure. Scheelites can be dated to determine the age of mineralization of ore deposits using the SmNd isotope method. Since the late 1980s, geoscientists have studied the Sm-Nd isotope systematics of scheelites from some famous gold deposits to constrain their ages, especially in the Archaean-Early Proterozoic greenstone belt type gold deposits [12][13][14][15][16][17][18][19] . However, there are almost no studies on the REE patterns and Sm-Nd geochronology of scheelites from the non-gold deposits.Fortunately, scheelite with large size and euhedral shape from Xuebaoding, Sichuan Province is an ideal mineral for the Sm-Nd geochronometry of non-golden deposits.The Xuebaoding W-Sn-Be deposit in Sichuan Province is different from other W-bearing deposits in that most W-bearing deposits are exploited mainly for tungsten or gold. The Xuebaoding deposit is very famous for scheelite, cassiterite, beryl, fluorite, muscovite, apatite, kesterite, quartz and feldspar. As a result, the deposit has been highly recognized in the world due to its large, euhedral, and colorful crystals. Up to now, much attention h...

“…Given the complex nature of instrumental drift as illustrated in Figure 8, it would be difficult to monitor and correct for the drift by using single or even several internal standards [1,30]. It is considered that the method of standard additions (SA) or isotope dilution (ID) can avoid or minimize the drift, and improve the accuracy and precision [31,32].…”

We also show that mass-time-intensity drift curve is smooth as recognized previously, for which the correction can be readily done by analyzing a qualitycontrol (QC) solution and using off-line Excel VBA procedure without internal standards. With these methods, we can produce data in reasonable agreement with recommended values of international rock reference standards with a relative error of < 8% and precision generally better than 5%. Importantly, compared to the widely used analytical practice, we can effectively save > 60% of time (e.g., < 24 hours vs. > 60 hours).

“…Analyses of acids, deionized water and procedural blanks give levels of <1 ppb for REE, Nb, Zr and Hf, relative to their concentration in the rocks. Detection limits (in ppm) were defined as 3r of the calibration blank (Xie et al, 1994). All samples were run with BCR-2 that has been analyzed routinely at the University of Saskatchewan ICP-MS laboratory (Appendix 3).…”
