The results of the zircon trace elements are listed in Table 4.All zircons show typical LREE depletions and HREE enrichments with positive Ce and negative Eu anomalies(Fig.13).Total zircon REE contents for both the Paodaoling and Wushi porphyries range from 350 to1200 ppm,whereas those for both the Huayuangong granites and Wushi quartz-syenites are from 1800 to 4400ppm.Zircons from the Wushi quartz-syenites also show LREE enrichments,suggesting that the zircons may have been contaminated by LREE-enriched minerals(e.g.,apatite)or inclusions(Wang et al.,2014).
