The Bayan Obo developing at the northern margin of the NCC could be taken as a proof that the NCC rifted from the Columbia supercontinent and formed an ocean basin along Bayan Obo Aulacogen in 1,350-1,320 Ma (e.g., Li et al, 2009;Shi et al, 2012;Yang, Fan, Santosh, Hu, & Wang, 2011;Zhang et al, 2009a;Zhang et al, 2012;Wang et al, 2017), perhaps even at 1.3-1.2 Ga (e.g., Hou, Santosh, Qian, Lister, & Li, 2008;Liu, Zhao, & Liu, 2014;Rogers & Santosh, 2002;Santosh, Maruyama, & Yamamoto, 2009;Wang, Zhou, Zhao, Chen, & Yan, 2014;Zhai, 2004;Zhao et al, 2003). If this was the case, the concept of "Bayan Obo Aulacogen" is not suitable for Bayan Obo Group's geological background.…”

Porphyritic olivine kimberlitic breccia, discovered in the Dörbed Banner of Inner Mongolia, Western China, is referred to as Longtou Shan Kimberlite in our study. This kimberlite occurs as a pipe in the Halahuogete Formation of Bayan Obo Group. Zircon U–Pb ages of Longtou Shan Kimberlite reveals a Mesoproterozoic age of ~1,552 Ma, constraining the deposition age of Halahuogete Formation to the Mesoproterozoic. Compared with Mesoproterozoic kimberlite of the ancient landmass, it can be inferred that the North China Craton is a member of the Ur ancient continent of the Columbia supercontinent. Furthermore, according to the tectonic background of the Bayan Obo Group, we raise this possibility that “Bayan Obo Aulacogen” should be renamed the “Bayan Obo Continental Rift.”

“…1A). The Yangtze Block consists of Archean crystalline basement, Meso-to Neoproterozoic folded basement and Paleozoic to Mesozoic cover sequence (Liu and Lin, 1999;Qiu et al, 2000;Zhou et al, 2012a;Wang et al, 2014). In the western Yangtze Block, the folded basement includes the Dongchuan (~1.7 to ~1.5 Ga) and Kunyang/Huili (~1.2 to ~0.9 Ga) Groups and equivalents (Sun et al, 2009;Zhao et al, 2010) that consist of greywacke, slate and other carbonaceous and siliceous sedimentary rocks.…”

“…The Yangtze Block is considered to preserve an important geologic record of the Late Paleoproterozoic-Mesoproterozoic convergence and breakup of the Columbia supercontinent [20][21][22][23][24][25][26][27][28][29][30][31][32][33][34]. In particular, the area between the western margin of the Yangtze Block (from the north of Kangding, Sichuan Province), the Yuanjiang county, the Yunnan Province to the south, the Puduhe Fault to the east, and the Yuanmou-Luzhijiang Fault to the west contains the most extensive distribution of the Paleoproterozoic to Proterozoic rocks in southern China.…”

“…This area is ideal to study the Precambrian rocks of the Yangtze Block, especially the Paleoproterozoic-Mesoproterozoic geology. Various types of magmatic rocks are located on the western margin of the Yangtze Block, e.g., Late Paleoproterozoic-Mesoproterozoic ultrabasic to acidic rocks [27,[35][36][37][38][39][40], and Paleoproterozoic-Mesoproterozoic sedimentary rocks, e.g., the Hekou Group, Dahongshan Group, and Dongchuan Group (DCG) [22,28,29,[41][42][43][44][45][46]. Recently, the study of these rocks has generated considerable amount of geochronological and geochemical data.…”

“…Moreover, the Late Palaeoproterozoic and Mesoproterozoic tectonic settings of this margin are not well defined. Currently, the interpretations range from an island-arc system related to the subduction that occurred 1.7-1.6 billion years ago [45,46] to a Late Paleoproterozoic-Mesoproterozoic plate-rift environment [22,28,29,31,42]. These different viewpoints constrain the understanding of the Late Paleoproterozoic-Mesoproterozoic tectonic setting of the Yangtze Block.…”

Precambrian Basement and Late Paleoproterozoic to Mesoproterozoic Tectonic Evolution of the SW Yangtze Block, South China: Constraints from Zircon U–Pb Dating and Hf Isotopes

et al. 2018

Zircon U–Pb dating and Hf isotopic analyses are performed on clastic rocks, sedimentary tuff of the Dongchuan Group (DCG), and a diabase, which is an intrusive body from the base of DCG in the SW Yangtze Block. The results provide new constraints on the Precambrian basement and the Late Paleoproterozoic to Mesoproterozoic tectonic evolution of the SW Yangtze Block, South China. DCG has been divided into four formations from the bottom to the top: Yinmin, Luoxue, Heishan, and Qinglongshan. The Yinmin Formation, which represents the oldest rock unit of DCG, was intruded by a diabase dyke. The oldest zircon age of the clastic rocks from the Yinmin Formation is 3654 Ma, with εHf(t) of −3.1 and a two-stage modeled age of 4081 Ma. Another zircon exhibits an age of 2406 Ma, with εHf(t) of −20.1 and a two-stage modeled age of 4152 Ma. These data provide indirect evidence for the residues of the Hadean crustal nuclei in the Yangtze Block. In combination with the published data, the ages of detrital zircons from the Yinmin Formation yielded three peak ages: 1.84, 2.30 and 2.71 Ga. The peaks of 1.84 and 2.71 Ga are global in distribution, and they are best correlated to the collisional accretion of cratons in North America. Moreover, the peak of 1.84 Ga coincides with the convergence of the global Columbia supercontinent. The youngest age of the detrital zircon from the Yinmin Formation was 1710 Ma; the age of the intrusive diabase was 1689 ± 34 Ma, whereas the weighted average age of the sedimentary tuff from the Heishan Formation was 1414 ± 25 Ma. It was presumed that the depositional age for DCG was 1.71–1.41 Ga, which was in accordance with the timing of the breakup of the Columbia supercontinent. At ~1.7 Ga, the geochemical data of the diabase were characterized by E-MORB and the region developed the same period A-type granites. Thus, 1.7 Ga should represent the time of the initial breakup of the Yangtze Block. Furthermore, the Yangtze Block continues to stretch and breakup until ~1.4 Ga, which is characterized by the emergence of oceanic island, deep-sea siliceous rock and flysch, representing the final breakup. In brief, the tectonic evolution of the Yangtze Block during the Late Paleoproterozoic to Mesoproterozoic coincided with the events caused by the convergence and breakup of the Columbia supercontinent, because of which, the Yangtze Block experienced extensive magmatic activity and sedimentary basin development during this period.
