英文摘要	The Sangong granite series of Ritu batholish include granodiorite, tonalite and quartz-diorite, also many xenoliths, which composed by sandstone slate inclusions, amphibolitie inclusions and dark microgramular mafic inclusions. The geochemistry characteristics of Sangong series, the host rocks, indicate high-silica, unsaturated-weak saturated of aluminum, talc-alkaline or high-K calc-alkaline, also LREE-enriched accompanying weak to middle Eu anomaly. The geochemical relevant covariance diagrams of the host rocks reveal the crust-mantle magma mixing production, in addition, the single-grain zircon U-Pb concordance diagrams of granodiorite shows the invasion time, 115. 5 +/- 0. 4Ma, so the series of mixed granite is correlated to the collision between the island arc and Bange microplat in the process of the Shiquanhe belt closing.
