The Ereendavaa area is located in the NE Mongolia, whereas various types of granitoids are distributed. The purpose of study is to understand the tectonic evolution of this area based on characteristics of granitoids. Therefore, we identified syn-collisional S-type and arc-related I-type granitoids. S-type granitoids were respectively formed at ca. 880 Ma, ca. 440 Ma and ca. 220 Ma. I-type granitoids were individually generated at ca. 540 Ma, ca. 470 Ma and ca 220 Ma in the Ereendavaa area.
