There were a great deal of biotite alkali-feldspar granite in the Yingchengzi gold deposit which located the western of Jiamusi massif, eastern of Zhangguangcailing area. We chosen biotite alkali-feldspar granite from the deposit for single zircon LA-ICP MS U-Pb dating., subdivided in to foue groups ages，as ages of 612±4Ma，495.2±2.7Ma，476.8±5.5Ma and 431±3Ma by the zircon analysis with LA-ICP MS, the date of 612±4Ma indicated t some granites formed in the late Proterozoic during the process of crustal growth; the date of 495.2±2.7Ma was consistent with the metamorphism of mashan group, the age of 431±3Ma was consistent with the regional metamorphism in the late Paleozoic, the real crystallization age of the biotite alkali-feldspar granite was 476.8±5.5Ma. The result indicated this area had happen crustal growth during the mid-new Proterozoic, and the new crust was opened formed ocean. Until the early of earlypaleozoic, the terranes between the ocean were collided and aroused granulite facies metamorphism with mashan group in the area. In late Early Paleozoic, the ocean was closed and formed syn-collisional granite which has the crust source characteristics in the western of Jiamusi massif. The ductile deformation with the collision offered some advantages for the gold deposit.
