The Hutuo Group belongs to the Early Proterozoic strata. As one of the most typical Paleoproterozoic strata in North China, the timing redefinition of the Hutuo Group is of great significance to the establishment of the early Precambrian stratigraphic chronology framework, the discussion of the early Precambrian geological evolution process in North China and the study of plate assembly. This article conducts a detailed study of the Dongye Subgroup strata of the Hutuo Group, collecting 24 detrital zircon samples from the Jian'ancun Formation of the Hutuo Group. From 23 similar age detrital zircons, we define the weighted average age of the bottom boundary of the Hutuo Group is 2469 Ma, and regional tectonic movements occurred in the Wutai area around 1855 Ma. According to the 1109 zircon ages in Hutuo Group from previous studies, we considered that the ages of >2.5 Ga are from underlying Gaofan subgroup and the maximum depositional age of Hutuo Group was early Paleoproterozoic. Secondly, the crust of the Wutai area was unstable at 2376 Ma, 2170 Ma, 2066 Ma, 1988 Ma, and 1825 Ma, resulting in multiple magmatic events. The 1825 Ma zircon age can further indicate the occurrence of the Lvliang movement, and provide a basis for the early Proterozoic North China Craton integration.
