Abstract— Reproducing the geological evolution of the Yenisei Range is important not only to understand how mobile belts at boundaries between ancient cratons tectonically evolved but also to gain an insight into how the Siberian craton was incorporated into the Nuna and Rodinia supercontinents. The paper presents geological, geochemical, and isotope geochronologic evidence of Meso- to Neoproterozoic events in the western margin of the Siberian craton and demonstrates that multiple pulses of intraplate magmatism occurred during the late evolution of the Yenisei Range. The rocks produced by these processes crystallized from high-temperature and hydrous magmas, which were rich in alkalis, iron, and most incompatible elements, as is typical of A-type anorogenic granites in intraplate environments. According to U–Pb zircon and monazite dates, the emplacement age of the granites is constrained between two peaks at 1380–1360 and 800–720 Ma. These magmatic events well correlate with the breakup ages of the Precambrian Nuna and Rodinia supercontinents and provide evidence that the Siberia was close to the North-Atlantic cratons (Laurentia and Baltica) during a long time span starting at 1.38 till 0.72 Ga, which is consistent with modern paleomagnetic reconstructions of the position of the supercontinents and the age spans when LIPS were formed.

叶尼塞山脉花岗岩类非造山岩浆作用：西伯利亚克拉通西部岩石圈伸展的证据

摘要：再现叶尼塞山脉的地质演化不仅对于了解古克拉通边界处的移动带如何构造演化很重要，而且对于深入了解西伯利亚克拉通如何并入努纳和罗迪尼亚超大陆也很重要。本文提供了西伯利亚克拉通西缘中新元古代事件的地质、地球化学和同位素年代学证据，并证明叶尼塞山脉晚期演化过程中发生了多次板内岩浆作用脉冲。这些过程产生的岩石是由高温含水岩浆结晶而成的，岩浆富含碱金属、铁和大多数不相容的元素，这是典型的板内环境中 A 型非造山花岗岩。根据 U-Pb 锆石和独居石日期，花岗岩的就位年龄限制在 1380-1360 和 800-720 Ma 的两个峰值之间。这些岩浆事件与前寒武纪 Nuna 和 Rodinia 超大陆的破裂年龄密切相关，并提供证据表明西伯利亚在从 1.38 到 0.72 Ga 的很长一段时间内靠近北大西洋克拉通（Laurentia 和 Baltica），这是一致的用现代古地磁重建超大陆的位置和 LIPS 形成的年龄跨度。
