Liaoning Xiuyan Sanjiazi mineralization concentration area in Qingchengzi mineralization concentrated area west of the Sanjiazi area, belonging to the western extension part of Qingchengzi mineralization belts. Within the mining area development in Waling adamellite of late Jurassic intrusive rocks, should have close relationship with local mineralization. Zircon SHRIMP U-Pb age weighted average value was 162.4 + 1.9Ma and represent magmatic crystallization age should be to Yanshanian magmatism and is part of the Jurassic granite in the eastern NCC. The whole rock chemical analysis results showed that the Waling adamellite for high-k calc alkaline magma series, which SiO2 (72.28-75.61) is more than or equal to 56%, Al2O3 (14.37-15.06) is more than or equal to 15% (very few below this value), MgO is less than 3% of, a / CNK value 1.035-1.083, were more than 1, with aluminum satiety and characteristics. Trace element data show that the loss of heavy rare earth elements (La/Yb) N is 18.06-22.66, Eu is not negative. With high Sr (497× 10-6~574 × 10-6) and low y (4.56 × 10-6~5.61 × 10-6) and Yb (0.47 × 10-6~0.62 × 10-6) in) feature and performance with adakitic affinity of I-type granite. Rock epsilon Hf (0) is negative, the epsilon Hf (t) to negative (-28.9 ~ 17.5), that Waling rock formation of crust derived material composition accounted for dominant position, single stage HF model ages (TDM) for an average of 1714Ma. Two stage HF model ages (tdmc) average 3704Ma. In summary, Waling rock formation to start from the Middle Jurassic (160mA) multi plate to the East Asian convergence of tectonic background, may is the product of melting of the crust in the thickened and adakite and copper mineralization is closely related to evidence.
