The Zhongtiao Mountain, an important part of the Trans-North China Orogen, North China Craton, holds well preserved significant evolution records of the Trans-North China Orogen. The Jiangxian Group is divided into the Henglingguan Subgroup and the Tongkuangyu Subgroup, the Henglingguan Subgroup consists predominantly of metamorphic clastic rocks, specifically quartzite and phyllite. In contrast, the Tongkuangyu Subgroup primarily comprises acid and basic volcanic rocks, with “bimodal” volcanic rocks alternating with normal sedimentary clastic rocks. Based on field investigation on the rock composition and stratigraphic characteristics and comprehensive analysis of zircon isotopic ages of the volcanic rocks, intrusive rocks, and detrital zircon of the Jiangxian Group, the age for this Group is estimated to be around 2200 Ma to 2120 Ma, corresponding to the Paleoproterozoic era. By integrating the geochemical characteristics of clastic and volcanic rocks with the evolutionary history of the Trans-North China Orogen, it is inferred that the Jiangxian Group likely originated in a tectonic environment linked to a paleo-active continental margin. Specifically, the Henglingguan Subgroup was deposited in an active continental margin basin, whereas the Tongkuangyu Subgroup originated in a volcanic arc of an active continental margin.
