“…It has been demonstrated that the lowermost crust (~5 km) of the northern NCC is mafic and contains zircons with Phanerozoic ages (e.g. Liu et al., ; Wei et al., ; Zhang et al., ). Here we demonstrate that the protoliths of these lower‐crustal rocks were formed by Phanerozoic magma underplating.…”

“…This has been exemplified by lower‐crustal granulite xenoliths that contain zircons with younger ages than the exposed basement rocks (Davis, ; Moyen et al., ). For example, Phanerozoic zircons (45–220 Ma) have been reported in granulite xenoliths from the Cenozoic basalts in the Hannuoba area of the North China Craton (NCC) (Fan et al., ; Liu et al., ; Wei, Zheng, Su, Ma & Griffin, ; Zheng et al., ). These ages are obviously younger than those of the rocks of the nearby exposed Archaean granulite terrane, and have been regarded as strong evidence for Phanerozoic underplating underneath Archaean cratons.…”

Evidence for post‐Archaean crustal growth via magma underplating is largely based on U–Pb dating of zircons from granulite‐facies xenoliths. However, whether the young zircons from such xenoliths are genetically related to magma underplating or to anatexis remains controversial. The lower‐crustal xenoliths carried by igneous rocks in the Chifeng and Ningcheng (North China Craton) have low SiO2 and high MgO, indicating that parental melts of their protoliths were of unambiguous mantle origin. The xenoliths contain abundant magmatic zircons with late‐Palaeozoic ages, and have more radiogenic zircon Hf‐isotope compositions and hence younger model ages than ancient crustal magmas and the “reworking array” of the basement rocks. Our data suggest that the granulites represent episodic magmatic underplating to the lower crust of this craton in Phanerozoic time. Considering the observation that regional lowermost crust (~5 km) is mafic and characterized by Phanerozoic zircons, this work reports an example of post‐Archaean crustal growth via magma underplating.

Recycling of Paleo-Asian Ocean carbonates and its influence on the lithospheric composition of the North China Craton

The deep carbon cycle, which plays a critical role in mantle evolution and Earth habitability, is closely linked to the recycling of carbonate-bearing rocks through subduction. Marine carbonates are subducted to different depths during the closure of oceanic basins, thus carry important signatures of the disappeared oceanic basins. Petrological and geochemical features of the Hannuoba carbonatites in the northern North China Craton indicate that they were formed by melting of limestone subducted to mantle depths. Here, we show that detrital zircons carried by these carbonatites have a broad spectrum of U-Pb ages from Precambrian to Phanerozoic. Precambrian age peaks are at ~2.
