Abstract:Exploring the growth and evolution of continental crust has always been one of the most fundamental challenges in Earth sciences. As one of the oldest cratonic blocks, the North China craton, which extensively records early Precambrian tectono- thermal events, is a key area for investigating this issue. Although there is a basic consensus that the Archean is the main period of crustal growth, the growth mechanism is still controversial. This paper summarizes recent studies on zircon U- Pb geochronology, Th- U contents, and Hf- O isotope data from early Precambrian studies across the North China craton, aiming to explore the growth and evolution of its continental crust. Our findings reveal the following: ① Archean to Paleoproterozoic rocks, especially Neoarchean rocks, are widely developed in the North China craton. Pre- Mesoarchean rocks are predominantly distributed in the Eastern block, while Mesoarchean to Neoarchean rocks are mainly concentrated in the Eastern block and the Trans- North China Orogen. In contrast, the Western block is dominated by Neoarchean to Paleoproterozoic rocks. ② The Hf- depleted mantle model ages closely match the U- Pb ages of Mesoarchean- Neoarchean zircons, suggesting dominant crustal growth during this period. However, after the Neoarchean, especially in the late Paleoproterozoic, the Hf- depleted mantle model ages of the zircons are significantly older than their U- Pb ages, indicating a shift to crustal recycling as the dominant process. ③ The Precambrian continental crust growth curve for the North China craton reveals rapid growth during the Mesoarchean and Neoarchean, with slower growth rates in the pre- Mesoarchean and late Paleoproterozoic. ④ Significant changes in zircon Th and U contents, Th/U ratios, and oxygen isotopes in the late Neoarchean and Paleoproterozoic mark a shift in geodynamic mechanisms. The late Neoarchean crustal growth was dominated by horizontal growth associated with subduction, indicating that modern- style plate tectonics likely initiated during the Neoarchean.
