英文摘要The Lushun-Dalian area of the South Liaodong Peninsula, in NE China, located in the SE margin of the North China Craton (NCC) exposes a suite of Middle-Late Proterozoic low-grade metamorphic sedimentary rocks which can be divided into a lower competent layer, a middle incompetent layer, and an upper competent layer on the basis of lithology and deformation style. Two stages of deformation recorded both in the metasedimentary rocks and a magmatic complex intruded in them indicate that the Lushun-Dalian area is a key region to decipher the Triassic-Jurassic tectonic evolution of the eastern NCC. The earliest D-1 deformation mylonitized the magmatic complex and thrusted it northeastward over the lowgrade metasedimentary rocks, in which a series of NE-verging folds and NE-directed brittle thrust faults developed. The D-2 deformation erased the D-1 fabrics in the incompetent layer by a top-to-the-NW ductile shearing and refolded the D-1 fabrics in the lower and upper competent units, producing a series of km-scale SW-plunging folds. New zircon secondary ion mass spectrometry and laser ablation-inductively coupled plasma-mass spectrometry U-Pb ages from the magmatic complex and the granite porphyry dikes intruded in it, combined with the unconformity between the low-grade metasedimentary rocks and the Early Cretaceous volcanic rocks, indicate that D-1 and D-2 occurred after 211 Ma and before the Early Cretaceous. The decrease of the deformation intensity of D-1 and D-2 from the Lushun-Dalian area toward the interior of the NCC in the NE and NW directions suggests that D-1 was the structural response in the overriding plate to the NCC-South China Block convergence during the Late Triassic to Early Jurassic, and D-2 was the structural response to the northwestward subduction of the Paleo-Pacific plate beneath the NCC in the Middle-Late Jurassic. The superimposition of D-2 on D-1 recorded a significant tectonic transformation from the nearly E-W-trending Tethysian domain to the NE-SW-trending Pacific domain.
