Through 1:250 000 geological mapping of Hegang City, the authors discovered adamellite in Motianling area in the middle and south of the Xiaoxinganling Mountain, which has the rapakivi texture, and was formed in Late Carboniferous.  A study of lithofacies, petrochemical and geochemical characteristics of the Motianling raparkivi granite and the rock assemblage shows that it is different from the representative anorogenic raparkivi granite of the Precambrian orogenic belt. It is the I-type granite in the orogenic belt related to the subduction of the plate system and the active continental margin of the island.
