Zheduoshan granitoids emplaced along Xianshuihe fault belt Consist Of earlier medium- to fine-grained granodiorite and monzogranite, slightly later predominated medium- to coarse-grained porphyry-like monzogranites and the latest granitoid pegmatites and aplites. The earlier medium- to fine-grained monzogranites have been dated by SHRIMP zircon U-Pb isotopes and an age of 18 +/- 0.3Ma is obtained. This SHRIMP zircon U-Pb age makes the time of emplacement of Zheduoshan granitoids and starting activation of the Xianshuihe fault belt, be predated for 6 Ma. Inherited zircons with 818 +/- 47 Ma and 156 +/- 8 Ma ages, respectively, are preserved in this sample. The earlier granodiorite and monzogranite samples were ploted into calc-alkaline and high-potassium calc-alkaline series domains and later porphyry-like monzogranite samples into shoshonite series domain in the K2O versus SiO2 diagram. All of these samples exhibit aluminium saturation to supersaturation. Earlier granodiorite samples display medium total REEs (162 x 10(-6) similar to 224 x 10(-6)), higher (La/Yb) (N) (=74 similar to 118) and positive Eu anomalies, and enrichment in LILEs, but depletion in the Nb, Ta, P and Ti in the primitive mantle normalized spider diagram, indicating that the granodioritic magma derived from lower degree of partial melting of calc-alkaline basaltic volcanic rocks. The earlier monzogranite samples show very similar geochemical characteristics to the earlier granodiorites, excepted that their total REEs and (La/Yb), are lower than these of granodiorites, Suggesting that the earlier monzogranite magma was most probably derived from lower degree partial melting of graywackes. Predominant later porphyry-like monzogranite samples display a wider total REE’s (the highest arrived to 533 x 10(-6)), the (La/Yb) (N) (the highest to 523), Obvious negative Eu anomalies, and intensive enrichment in LILEs, but depletion in Nb, Ta, Sr, P and Ti in the primitive mantle normalized spider diagram. These porphyry-like monzogranites also exhibit (Sr-87/Sr-86), = 0.7084 similar to 0.7133 and epsilon(Nd)(t) = -5.67 similar to -8.69, suggesting that the later monzogranitic magma was most probably derived from lower degree partial melting of Proterozoic Upper continental materials of siltstones and/or shales. These geochemistry features in various kind of granitoids in Zheduoshan intrusion indicate that the partial melting source materials have inherited some geochemisty characteristics of Proterozoic active continental margin arid underwent high-pressure metamorphism, and partial melting residuals should dominate garnet. The partial melting was probably produced with early shear melting process of Xianshuihe fault belt, also occurred strong compression before the magmatism to produce the high-pressure metamorphism.
