Due to the influence of Paleoproterozoic metamorphism and deformation, the structure characteristics of the Archean basement of the North China Craton were blurred. The central region of the Western Shandong Province, located in the eastern part of the North China Craton, developing 2.7~2.5 Ga supracrustal rocks, are almost not affected by the Paleoproterozoic events. In this study, detailed field structure analysis and geochronological work were carried out. We suggested that the Taishan Group was subjected to three stages of deformations: early foliation(S1) and tight folds(F1) formed in the stage DA-1. Large upright folds, foliation(S2) and thrust faults formed in the stage DA-2. In the stage DA-3, lots of ductile shear zones formed. Combined with some published chronological data, we proposed that the stage DA-1 occurred in >2.56~2.53 Ga, the stage DA-2 occurred in 2.53~2.52 Ga, the stage DA-3 occurred in 2.52~2.50 Ga. Large number of structural geometric features in peak deformation stage indicate that the deformations of the Taishan group is different from those of the dome and keel structure under the vertical mechanism. It is similar to the structure formed by the lateral extrusion orogeny of the Phanerozoic. Accordingly, we suggest that the Archean horizontal structure in Western Shandong is the result of horizontal movement under the plate tectonic system.
