摘要

华北克拉通(NCC)在罗丁尼亚的位置仍然存在争议,因为与罗丁尼亚组合相关的岩浆和造山记录明显缺失。然而,在NCC东南部发现的大量来自晚埃迪卡拉世丰台组的碎屑锆石为评估NCC与Rodinia的关系提供了一个重要的机会。碎屑锆石U-Pb-Hf同位素分析揭示了八公山地区和四十里长山地区丰台组明显的年龄模式。八公山地区丰台组以中元古代-新元古代过渡锆石为主,其突出年龄峰约为0.99 Ga,次峰约为1.19 Ga、1.43 Ga、1.65 Ga、1.92 Ga和2.50 Ga。四十里长山地区辉长岩以新太古代—古元古代和次生中元古代锆石为主,其主要年龄峰值约为2.04 Ga,次峰值约为0.90 ~ 1.00 Ga、1.12 ~ 1.48 Ga、1.87 Ga、2.31 Ga和2.46 Ga。丰台组沉积来源于华北盆地东南部中元古代晚期-新元古代早期盖层和/或太古宙-古元古代基底。新太古代-古元古代锆石来自基底岩和/或盖层碎屑岩单元,而中元古代锆石则来自盖层碎屑岩单元的再循环碎屑。此外,中元古代-新元古代过渡锆石被解释为覆盖层碳酸盐岩单元中的凝灰岩组分。这些过渡锆石的元素特征表明,相关的长英质岩浆活动发生在大陆弧造山环境中。锆石εHf(t)值在1385 ~ 778 Ma之间呈下降趋势,表明存在内部造山体系。这些证据支持了NCC东南部发生格伦维利亚时代造山作用的假设,从而证实了NCC参与了Rodinia组合,特别是NCC东南部与Laurentia西北部的连接,这些证据通过古地磁数据和前低温期盖层的物源分析得到了证实。

Rodinia supercontinent assembly in the southeastern North China Craton: Detrital zircon evidence from the late Ediacaran Fengtai Formation
The position of the North China Craton (NCC) within Rodinia remains debated due to the notable absence of magmatic and orogenic records associated with the Rodinia assembly. Nevertheless, the discovery of abundant Grenvillian-aged detrital zircons from the late Ediacaran Fengtai Formation diamictites in the southeastern NCC provides a significant opportunity to evaluate the NCC’s affiliations with Rodinia. Detrital zircon U–Pb–Hf isotopic analyses reveal distinct age patterns of the Fengtai Formation in the Bagongshan and Sishilichangshan areas. The Fengtai Formation in the Bagongshan area is notable for its Mesoproterozoic–Neoproterozoic transition zircons, exhibiting a prominent age peak at approximately 0.99 Ga and subsidiary peaks at about 1.19 Ga, 1.43 Ga, 1.65 Ga, 1.92 Ga, and 2.50 Ga. Conversely, the diamictite in the Sishilichangshan area is marked by Neoarchean–Paleoproterozoic and secondary Mesoproterozoic zircons, featuring a primary age peak at about 2.04 Ga and minor peaks at approximately 0.90–1.00 Ga, 1.12–1.48 Ga, 1.87 Ga, 2.31 Ga, and 2.46 Ga. The Fengtai Formation sediments were derived from the late Mesoproterozoic–early Neoproterozoic cover and/or Archean–Paleoproterozoic basement in the southeastern NCC. The Neoarchean–Paleoproterozoic zircons are attributed to the basement rocks and/or the cover’s clastic rock units, whereas the Mesoproterozoic zircons represent recycled detritus from the cover’s clastic rock units. Furthermore, the Mesoproterozoic–Neoproterozoic transition zircons are interpreted as recycled tuffaceous components from the cover’s carbonate rock units. The elemental signatures of these transition zircons suggest that the associated felsic magmatic activity occurred in a continental arc orogenic setting. Notably, the declining trend of zircon εHf(t) values from 1385 to 778 Ma is indicative of the presence of an interior orogenic system. These lines of evidence support the hypothesis of Grenvillian-aged orogenesis occurring in southeastern NCC, thereby affirming the NCC’s involvement in the Rodinia assembly, particularly the southeastern NCC–northwestern Laurentia connection, as demonstrated through paleomagnetic data and provenance analyses of the pre-Cryogenian cover.

期刊介绍: Precambrian Research publishes studies on all aspects of the early stages of the composition, structure and evolution of the Earth and its planetary neighbours. With a focus on process-oriented and comparative studies, it covers, but is not restricted to, subjects such as: (1) Chemical, biological, biochemical and cosmochemical evolution; the origin of life; the evolution of the oceans and atmosphere; the early fossil record; palaeobiology; (2) Geochronology and isotope and elemental geochemistry; (3) Precambrian mineral deposits; (4) Geophysical aspects of the early Earth and Precambrian terrains; (5) Nature, formation and evolution of the Precambrian lithosphere and mantle including magmatic, depositional, metamorphic and tectonic processes. In addition, the editors particularly welcome integrated process-oriented studies that involve a combination of the above fields and comparative studies that demonstrate the effect of Precambrian evolution on Phanerozoic earth system processes. Regional and localised studies of Precambrian phenomena are considered appropriate only when the detail and quality allow illustration of a wider process, or when significant gaps in basic knowledge of a particular area can be filled.
