The Mangling granite is located on the north side of the Shannan—Danfeng foult, eastern sector of the north Qinling Orogen. The granite is in North—West—West strech and in agreement with structural lineament. The paper reports the results of Zircon LA ICP MS U Pb age and geochemical data. The results show that the Mangling granite includs two granite emplacements. Early Monzogranite whose ages ranging from 158.4±1.8Ma to 160.5±1.3 Ma belongs to Late Jurassic Early Cretaceous period and the late alkali granite has an age of 124.1±2.0 Ma belonging to Middle Cretaceous. In addition, sample 09CL264 give inherited core age of 1883±36Ma and 1860±35 Ma belonging to proterozoic and may represent its protolith age. In geochemistry, monzogranite with the characteristics of high SiO2, K2O+Na2O , K2O/Na2O>1 and high Sr low Yb, Y. The alkali granite has the characteristic of high SiO2, K2O+Na2O, K2O/Na2O<1 and low Sr low Yb, Y. The εHf(t) values are from -9.4 to -3.1 which is consistent with previous study on εNd(t). In conclusion, the Mangling granite has character of multi source and the main is proterozoic material in lower crust.
