Early Permian A‐type Granites in the Zhangdaqi Area, Inner Mongolia, China and Their Tectonic Implications

There is a controversy regarding the amalgamation of Xing'an and Songnen Blocks along the Hegenshan‐Heihe Suture (HHS) in the eastern Central Asian Orogenic Belt (CAOB). To solve this problem, we performed detailed study on the granites from the Zhangdaqi area, adjacent to the north of the HHS in the northern part of the Great Xing'an Range, NE China. Geochemically, the granites in the study area are metaluminous‐weak peraluminous and high‐K...
