Based on systematic collection of ages and geochemical data, this paper has preliminarily established geochronological framework of the Late Mesozoic granitoids in Russian Far East area. These granitoids can be mainly divided into two periods, i. e., Jurassic period (178~151 Ma) and Early Cretaceous period(142~122 Ma). The Jurassic granitoids consist mainly of granites, granodiorites and quartz monzonite, and show metaluminous-peraluminous high-K, calc-alkaline granites characteristics. The Early Cretaceous granitoids consist mainly of granite, quartz diorite and quartz monzonite, and are characterized by peraluminous calc-alkaline, high-K-calc-alkaline and shoshonite granites. REE patterns of two periods of granitoids are all of right-inclined type, their HREE assume relatively flat curves and are enriched with large ion lithopile elements(such as U and K) and LREE.
