英文摘要Recognizing terminal ridge subduction is of first-order importance in chronicling the tectonic timeline of any accretionary orogens, but remains elusive in the final suturing zone of the Paleo-Asian Ocean along the Solonker- Xar Moron-Changchun-Yanji swath. Here we report two generations of ultramafic-mafic to intermediate intrusions from north-ern Liaoning, North China, linking eastern Central Asian Orogenic Belt and northern North China Craton. The ca. 259 Ma appin-ites show variable enrichment in large-ion lithophile elements (LILEs) but depletion in high-field strength elements (HFSEs), and variably enriched isotopic compositions with eNd(t) of 11.8 to 2.4 and zircon eHf(t) of -15.7 to +5.0. These petro-geochemical traits argue for their derivation from partial melting of subduction-modified lithospheric mantle. By contrast, the high-Mg diorites of 226-223 Ma display decoupling features between LILEs and HFSEs and juvenile isotopic signatures with eNd(t) of -0.3 to +2.6 and zircon eHf(t) of +5.4 to +11.4. These characters are con-sistent with a magmatic origin from partial fusion of sediment-fertilized asthenospheric mantle. Synthesizing the two mantle-melting events with regional coeval igneous activi-ties leads to the identification of Late Perm-ian (265-250 Ma) and Middle-Late Trias-sic (241-218 Ma) magmatic flare-ups with a 10-15 m.y. lull along the northern North China Craton. This magmatic tempo tends to record a salient mantle replacement from hydrous metasomatized lithosphere to anhy-drous asthenosphere. In combination with ensuing progressive crustal growth, simul-taneous metamorphism, and structural ac-tivities, these diverse manifestations make a compelling case of ridge subduction and con-comitant slab window formation during the eventual closure of the Paleo-Asian Ocean along the Solonker-Xar Moron-Changc-hun-Yanji swath.
