Neoproterozoic granitic gneisses are widely developed in the Sulu UHP metamorphic belt, which are commonly considered to have affinity with the Yangtze Craton. Based on new survey data and previous researches, this paper puts forward a new insight that the Neoproterozoic granites were the product of the continental breakup of the North China Craton in the Neoproterozoic, which deeply subducted southward as the continental margin of the Jiaobei Terrane during the Triassic collision between the South and North China blocks. Several lines of evidence are shown as follows:① the Neoproterozoic granites intruded into the metamorphic rocks of the Jiaobei Terrane of the North China Craton, and the Wulian- Jimo- Muping fault zone is not the initial boundary between the North Sulu UHP Metamorphic Belt and the Jiaobei Terrane. ② The Neoproterozoic granitic gneisses contain a large amount of crustal rocks from the Jiaobei Terrane, recording the cratonization event of ～1.85 Ga in the North China Craton. ③ There is no Triassic arc magmatic record in the Jiaobei Terrane, but abundant Neoproterozoic inherited zircons have been identified in the Late Jurassic granites. ④ It is evident that the southeastern margin of the Jiaobei terrane underwent Triassic metamorphic event of amphibolite facies, consistent with Triassic subduction. ⑤ Regional geophysical information indicates that the deep crust of the North Sulu UHP metamorphic belt belongs to the North China Craton and its NE trending tectonic direction obliquely cut by the Wulian- Jimo- Muping fault. The new consideration will improve understanding the Neoproterozoic evolution of the North China Craton and the formation process of the Dabie- Sulu metamorphic belt, providing a new perspective for Mesozoic gold mineralization in the Jiaodong Peninsula.
