Tectonic Origin

As a main part of the North China craton collage system, the tectonic origin of the Bainaimiao arc terrane is still hotly debated, especially its relationship with the North China craton. Thus, we report on a field-based petrological and zircon U-Pb-Hf isotopic study of (meta-)sedimentary and volcanic rocks from the Bainaimiao arc terrane and northern margin of the North China craton in the Damao region. The lower and middle successions of the Bayan Obo Group from the northern North China craton, including the Dulahala, Jianshan, Halahuogete, and Bilute Formations, were deposited ca. 1.81−1.35 Ga and show age peaks at 1.85, 1.90, 2.0, and 2.5 Ga. This age pattern is in accordance with the coeval and extensively outcropped metamorphosed basement rocks of the northern North China craton. The upper succession, including the Bayinbaolage and Hujiertu Formations, deposited ca. 1.19−0.92 Ga, shows age peaks at ca. 1.35, 1.57, and 1.69 Ga, and sediments were derived from coeval rift-related magmatism characterized by a significant increase in positive εHf(t) values in detrital zircons. Thus, the Bayan Obo Group can be subdivided into North China craton basement−derived sediments and Mesoproterozoic to Neoproterozoic rift-derived sediments, and the change of the provenance was probably caused by the ca. 1.35−1.30 Ga rifting event related to the breakup of the Nuna supercontinent. In the Bainaimiao arc terrane, zircon U-Pb geochronological results of (meta-)sedimentary rocks indicate they were formed in the Neoproterozoic and Paleozoic and have mainly late Paleoproterozoic to Neoproterozoic ages (ca. 0.6−0.9, 1.1−1.2, 1.4−1.7, and 1.8−2.0 Ga) with peaks at ca. 0.86, 0.96, 1.15, 1.47, 1.66, 1.75, 1.80−1.87, and 1.94 Ga. The abundant Neoproterozoic ages for the Bainaimiao arc terrane detrital zircons are distinct from the scarcity of these ages in the northern North China craton, southern Siberia (age peaks at ca. 1.87, 1.92, and 2.0 Ga), and Mongolia (age peak at ca. 0.62, 0.83, 0.93, 1.84, and 2.0 Ga), but they are similar to the features of the Tarim craton (age peaks at ca. 0.62, 0.85, 1.15, 1.47, 1.66, 1.75−1.80, 1.85, and 1.94 Ga). Together with the recognition of a possible preexisting Proterozoic basement (ca. 0.7−2.0 Ga) in the Bainaimiao arc terrane, as evidenced by the Hf model ages of continental arc magmatism in the Bainaimiao arc terrane, this late Paleoproterozoic to Neoproterozoic detritus probably resulted from local recycled sedimentation, and the preexisting Bainaimiao arc terrane basement rifted away from a continent with Tarim craton affinity. The rifting probably occurred between ca. 0.6 and 0.52 Ga, because the reworking of the Precambrian rocks in the North China collage system occurred between ca. 520 and 230 Ma.

The late Palaeozoic was an important period of tectonic evolution for the northern margin of the North China Craton (NCC). The source(s) and tectonic setting of early Permian granitoid rocks emplaced along the northern margin of the NCC are still unclear. These granitoids formed between ~295.4–276.1 Ma (uncertainties ranging from ±1.5 to ±7.8 Ma) according to zircon laser ablation inductively coupled mass spectrometry (LA-ICP-MS) and sensitive high-resolution ion microprobe (SHRIMP) U-Pb data. The Dadongou (DDG) pluton is an A1-type granite and the Dananfangzi (DNFZ) pluton is an A2-type granite. The Erdaowa (EDW), Lisicun (LSC), Wuhai (WH) and Gehuasitai (GHST) plutons are I-type granites. The Yuanbaoshan (YBS) dykes are diorite and syenodiorite. All the granitoids are enriched in large ion lithophile elements and light rare earth elements, depleted in high field strength elements and have negative εNd(t) and εHf(t) values. The A1-type granite was formed by the melting of the mafic crust. The A2-type granite was derived from partial melting of tonalite gneiss from the NCC crust and mantle materials. The EDW, LSC, WH and GHST granites mainly originated from partially melted granulite, with some mantle input. The YBS dykes are formed by the magma mixing of hot mantle melt and the relatively cold crustal magma. The northern margin of the NCC experienced anorogenic and collision tectonic stages, and the structural setting started to transform to post-collision at the later period of early Permian.
