A great deal of early-to-mid Early Cretaceous magmatic activities have been recorded in the Zhalantun area of Inner Mongolia, while the late Early to Late Cretaceous magmatic rocks have been barely reported (Guo et al., 2018; Zhang Xiangxin et al., 2017). At present, only a few Late Cretaceous magmatic activities were reported in the Arongqi area, such as volcanic rocks of the Gushanzhen Formation. However, the Gushanzhen Formation lacks accurate isotopic age, and contemporaneous intrusive rocks has not been reported yet. In this work, we collected the volcanic rocks from the Gushanzhen Formation and contemporaneous intrusive rocks in the Zhanlantun and nearby, and aim to figure out the formation ages of volcanic rocks of the Gushanzhen Formation and accompanied intrusive rocks by analyzing zircon U-Pb isotopes (Fig. 1).
