摘要

1. Objective The Xing'an block (XB) is located in the eastern part of the Xingmeng orogenic belt, bounded by Erguna block (EB) to northwest and the Songnen block (SB) to the southeast (Fig. 1a). The Xinghuadukou Group is generally considered to be the metamorphic basement of the major blocks in the Xingmeng orogenic belt, while the depositional age is still debated.
