There is a long- standing controversy about the depositional age and tectonic significance of the Luanchuan Group located between the tectonic units of the Qinling orogenic belt and the North China Craton (NCC). In this paper, the provenance and regional comparative analysis of Luanchuan Group from the perspective of zircon U- Pb chronology and Hf isotopes could provide important evidence of late Precambrian tectonic evolution in the southern margin of NCC. The crystallization age of epi- metamorphic trachyte from the Dahongkou Formation in the upper part of the Luanchuan Group is 854±8 Ma, and its petrogenesis is mainly due to the recycling of Late Paleoproterozoic continental crust. The depositional age of the Luanchuan Group is constrained between 917~844 Ma by the youngest clastic zircon U- Pb age of the metaclastic rocks of the Luanchuan Group and crystallization age of epi- metamorphic trachyte from the Dahongkou Formation and related intrusive rocks in the Luanchuan area, which belong to the Qingbaikou period. There are similar U- Pb ages and two- stage Hf model ages (TDM2) of detrital zircons amongst upper and middle parts of the Baishugou Formation, the Meijiaogou Formation and the Yuku Formation of the Luanchuan Group in the Luanchuan area. The U- Pb ages are mostly 1. 85 to 1. 10 Ga, which indicates that the North Qinling Terrane (NQT) was the most probable provenance, and TDM2 are between 1. 33~2. 92 Ga, which signifies that the provenance area has undergone 4 episodes of Proterozoic crustal accretion at ~1. 45 Ga, ~1. 8 Ga, ~2. 1 Ga and ~2. 5 Ga. The change in the provenance of Luanchuan Group from NCC to NQT and its sedimentary tectonic setting from passive continental margin to collisional orogeny and post- collisional extension environment during sedimentation of the Baishugou Formation are suggested by marked differences in the detrital zircon age spectrum between lower parts of the Baishugou Formation and other strata of the Luanchuan Group. A Meso- Neoproterozoic tectonic belt similar to the NQT, which essentially belongs to a part of the NCC, developed at least in the eastern and the southern margin of the NCC. The tectonic belt was strongly involved in the Columbia supercontinent breakup process and the Rodinia supercontinent convergence, and was briefly combined with the NCC during the early Neoproterozoic era to transform into main provenance for the peripheral sedimentary basin of the NCC.
