The Great Xing’an Range (GXAR) is one of the most important metallogenic belts in China. Previous study has shown that porphyry Cu-Mo deposit distributed in the northern Great Xing’an Range formed mainly in two stages: (1) Early Ordovician, such as Duobaoshan and Tongshan deposits (Liu et al., 2017); 2) Triassic-Early Jurassic, including Wunugetushan, Taipingchuan and Badaguan deposits (Tang et al., 2016). In recent years, two potential porphyry Cu-Mo deposits, Huoluotai and Xiaokele, were discovered in the Erguna Block, northern GXAR (Figs. 1a–b). However, the ore formation ages and regional metallogenic regularity are ambiguous due to the lack of isotopic ages. Two zircon U-Pb ages from the orecausative granites were reported in this paper, with the aims to constrain the metallogenic ages and provide evidence for study of the regional metallogenic regularity and ore prospect prediction.
