...Keke Sun; Bin Chen Abstract The Shimensi deposit (South China) is a newly discovered W-Cu-Mo polymetallic deposit with a reserve of 0.76 million tones WO 3 , one of the largest tungsten deposits in the world. We report elemental and Sr-Nd isotopic data for scheelites from the giant deposit...

Chondrite-normalized REE patterns of scheelites from the Shimensi deposit. (a) Scheelites hosted in the porphyritic granite (DHT-138) exhibit complicated REE patterns, with negative Eu anomalies in the scheelites precipitated from “primitive” fluid and positive Eu anomalies in those from more evolved fluid. (b) A single scheelite from the Neoproterozoic granite (DHT-102) exhibit complicated Eu anomalies in the REE patterns, with negative anomalies seen in the center and positive Eu anomalies in the rim. (c) Scheelites in the Neoproterozoic granite (DHT-104) exhibite positive Eu anomalies in the REE patterns. (d) Scheelites hosted in quartz vein show exclusively positive Eu anomalies in the REE patterns. (e) Fluorite coexisted with scheelite hosted in the Neoproterozoic granite shows enriched HREE. (f) Wolframites hosted in quartz vein show no Eu anomalies and enriched HREE in the REE patterns. Scheelites with negative Eu anomalies are shown as red lines, and scheelites with positive Eu anomalies as black lines. Also shown for comparison are the REE data of the Mesozoic porphyritic granite, fine-grained granites (blue lines; unpublished data), and the granite porphyry (gray lines; unpublished data). The normalization values were from Sun and McDonough (1989). (Color online.)

(a) (87Sr/86Sr)i vs. εNd(t) diagram for scheelites of the Shimensi deposit. The Sr and Nd isotopic data of the Mesozoic porphyritic granite, fine-grained granite and granite porphyry are from Mao et al. (2014), the Neoproterozoic granites are from Wu et al. (2006), and the Shuangqiaoshan group rocks are from Zhang et al. (2012). Isotope modeling for a simple mixing between the Mesozoic porphyritic granite and the Shuangqiaoshan Group, the porphyritic granite with Sr = 75.6 ppm, ISr = 0.721, Nd = 17.4 ppm, εNd(t) = −5.1; the Shuangqiaoshan Group with Sr = 120.6 ppm, ISr = 0.759, Nd = 31.1 ppm, εNd(t) = −12.1. (b) Plots of Nb+Ta vs. (87Sr/86Sr) for scheelites in the Shimensi deposit. Note that the scheelites precipitated from “primitive” fluid (the porphyritic granites) show higher Nb+Ta and lower Sr isotopic ratios than those from evolved fluids (the Neoproterozoic granites), except one data point with low Sr isotopic ratio, which could be caused by less contribution from the surrounding rocks.

Distribution of the Mesozoic granites and volcanic rocks in South China. Also shown are the location of the Jiangnan orogen and Shimensi ore deposit (modified after Zhou et al. 2006; Deng et al. 2014). The Jiangnan orogen is mainly consisted of greenschist facies Shuangqiaoshan Group meta-sediments (and small amounts of meta-volcanics) with age of 860–825 Ma (detrital zircon ages; Wang et al. 2014b) and un-deformed Jiuling granite with zircon U-Pb age of 819 ± 9 Ma (Li et al. 2003), which intruded into the Shuangqiaoshan Group.
