Abstract:   The tectonic evolution of the Neoarchean North China Craton has been diversely debated, and it is necessary to conduct metamorphic studies. Mafic granulites from the Qingyuan terrane in North Liaoning were selected for systematic studies of petrography, mineral chemistry, phase equilibria modeling, and zircon dating to document their metamorphic evolution and tectonic significance. The selected mafic granulite sample is divided into garnet-bearing domains (19DJ07-GD) and garnet-free domains (19DJ07-NGD). The garnet-bearing domains are banded and inhomogeneous distributed. Both domains develop two phases of granulite facies assemblages. The first phase assemblages are dominated by orthopyroxene, clinopyroxene, amphibole, biotite, plagioclase, and quartz with garnet in the garnet-bearing domains. The first phase plagioclase (Pl₁) has complex compositional zoning with X_An (anorthite content) increasing from core to mantle and decreasing towards rim. The first phase amphibole (Amp₁) shows increasing Ti from core to mantle and decreasing Ti to rim. These mineral zoning and inferred mineral assemblages suggest that the first phase granulite facies metamorphism shows anticlockwise P–T paths characterized by pre-peak compression with heating and post-peak cooling with decompression. The peak P–T conditions are constrained to be 0.8~0.9 GPa/900~950 ℃ according to pseudosection modeling, reaching HT–UHT (high–ultrahigh temperature) conditions. Zircon dating yielded a metamorphic age of 2498 ± 6.9 Ma (MSWD = 0.39), representing the time of the post-peak cooling process. Combined with the “dome-and-keel” structure, the anticlockwise P–T paths, and the metamorphic time of mafic granulite which is consistent with the late pulse of the TTG magmatic activity, the UHT granulite facies metamorphism is considered to be controlled by the Archean unique vertical tectonics/sagduction. The second phase assemblages are characterized by the locally grown symplectites or coronae of garnet + quartz ± clinopyroxene, representing HP granulite facies related to a Paleoproterozoic orogeny.
