“…The TNCO is a Palaeoproterozoic continental collision zone formed at ~1.85 Ga from the amalgamation of the Eastern and Western crustal blocks which contain Archean and Paleoproterozoic rocks [31−38]. The majority of the igneous rocks found in this belt are calc-alkaline and have affinities to magmatic arc rocks [36,39,40]. Early tectonic models assumed that the Hengshan and Fuping gneiss assemblages represented an older basement to the Wutai greenstone terrane [36−38].…”

Microorganisms that inhabit sub-seafloor lavas are capable of etching volcanic glass and creating micron-sized tunnels and pits. Mineralization of these bioalteration traces ensures that these textures survive deformation and transformation of the host glass to metamorphic minerals. The fossil record of such bioalteration textures extends far beyond volcanic glass from in-situ oceanic crust to include meta-volcanic glass from ophiolites and Precambrian greenstone belts. Investigation of petrographic thin section reported here from ~2.52 Ga tholeiitic pillow lavas from the Wutai Group of N. China found filamentous micro-textures. Laser Raman spectroscopy confirmed that these textures are mineralized by titanite. Moreover, the Wutai micro-textures are comparable in size, morphology and distribution to bioalteration textures from Archean greenschist facies pillow lavas. In-situ U-Pb dating of the titanite by laser ablation multi-collector inductively coupled plasma mass spectrometry (LA-MC-ICP-MS) gives an age of 1.81 ± 0.12 Ga (2σ, n=22, 206 Pb/ 238 U weighted average). This provides a minimum age for the mineralization of these candidate bioalteration textures and corresponds to a regional metamorphic event. This also represents a minimum age estimate for the timing of bioalteration and is compatible with the existence of a Late Archean-Proterozoic sub-seafloor biosphere. meta-volcanic glass, microbial bioalteration, titanite, sub-seafloor biosphere, Archean, North China Craton Citation:McLoughlin N, Fliegel D J, Furnes H, et al.

“…1). Both the Fuping and Hengshan Complexes are dominated by gray tonalite-trondhjemite-granodiorite (TTG) gneisses, mafic granulites, and supracrustal rock assemblages at amphibolite-to granulite-facies metamorphic grade (Zhao et al 2001;Guan et al 2002;Liu et al 2002aLiu et al , b, 2004Liu et al , 2005Kröner et al 2005Kröner et al , 2006O'Brien et al 2005). The Fuping TTG gneisses were emplaced between 2523 and 2486 Ma and are largely coeval with the Hengshan TTG gneisses dated at 2524-2479 Ma (Liu et al 2002b;Guan et al 2002;Zhao et al 2002;Kröner et al 2005a, b).…”

Detrital zircon U-Pb ages, whole-rock Nd isotopic, and geochemical data of metasedimentary rocks from the Wutai Complex in the Central Zone, North China Craton, have been determined. Compositionally, these rocks are characterized by a narrow variation in SiO 2 / Al 2 O 3 (2.78-3.96, except sample 2007-1), variable Eu anomalies, spanning a range from significantly negative Eu anomalies to slightly positive anomalies (Eu/Eu* = 0.58-1.12), and positive e Nd (t) values (0.1-1.97). The 18 detrital zircons of one sample yielded age populations of 2.53 Ga, 2.60 Ga, and 2.70-2.85 Ga. Geochemical data reveal intermediate source weathering, varying degrees of Kmetasomatism in the majority of these metasedimentary rocks, whereas other secondary disturbances seem to be negligible. Detailed analysis in detrital zircon U-Pb geochronology, whole-rock Nd isotope, and geochemistry shows that these metasedimentary rocks are derived from a mixed provenance. The predominant derivation is from the late Archean granitoids and metamorphic volcanics in the Wutai Complex, and there is also input of older continental remnants, except TTG gneisses, from the Hengshan and Fuping Complexes. The sediments were probably deposited in fore-arc or/and intra-arc basins within an arc system.

“…Nevertheless, several linear tectonic belts have been defined, i.e., the Jinyu Mobile Belt/Central Zone/Trans-North China Orogen/Sanggan Belt, the Fengzhen Mobile Belt/Khondalite Belt/Inner Mongolia Suture Zone, and the Jiao-Liao-Ji (Liaoji) Mobile/Orogenic Belt (e.g., Zhai et al 1993Zhai et al , 2005Guo et al 2005Guo et al , 2012Zhao et al 2000Zhao et al , 2001aZhao et al , b, 2005Li et al , 2000Kusky et al 2001Kusky et al , 2007Kusky and Li 2003;Zhai and Liu 2003;Zhai and Peng 2007;Kröner et al 2005a, b;Liu et al 2005;Santosh et al 2007aSantosh et al , b, 2012Santosh et al , 2015Trap et al 2007Trap et al , 2009aTrap et al , b, 2012Zhai and Santosh 2011;Zhao and Zhai 2013;Peng et al 2014).

It is well known that there are widespread Paleoproterozoic high-grade rocks, mainly garnet amphibolites and granulites, in the North China Craton. The granulites could be classified into two types, the high-pressure granulites and (ultra-) high-temperature granulites. The high-pressure granulites mainly distribute in the Huai'an-Xuanhua, Hengshan, Fuping, Zanhuang, Qianlishan-Helanshan, and Jiaobei regions (the central and east of the craton), while the (ultra-)high-temperature granulites distribute mainly in the Liangcheng-Jining-Zhuozi and the Daqingshan regions (west of the northern margin of the craton). Nevertheless, (ultra-) high-temperature granulites have been also discovered in northeast Hebei, north Henan, Shandong and Liaoning provinces, and the Korean peninsula, and some drilling cores from under the Ordos basin, though some of them might be formed in the Late Archean. The Paleoproterozoic high-grade metamorphism has partly overprinted on the Late Archean low-to high-grade rocks. Both types of granulites have recorded clockwise P-T paths, which might indicate a process similar to those happened in the Phanerozoic orogenic belts. In the past 20-30 years, several different tectonic models have been introduced to interpret the environments of the Paleoproterozoic granulites in the North China Craton. However, there are several things need to be clarified before any conclusion, e.g., (1) the distribution of the different types of high-grade rocks; (2) the relationship between the high-pressure granulites and the (ultra-)high-temperature granulites; and (3) the exhumation rate and genetic mechanism of these rocks. These Paleoproterozoic high-grade rocks in the North China Craton are more complex than any high-grade rocks in the Phanerozoic orogens, and await further study.
