英文摘要The ductile Kaiyuan-Jiapigou Shear Zone (KJSZ) is located within the eastern part of the northern margin of the North China Craton (NCC). The foliation within the shear zone generally dips at 55 degrees towards N20 degrees and contains a lineation that plunges at 40 degrees towards N30 degrees. Field and thin section observations and quartz c-axis fabrics of the KJSZ indicate that this zone records top-to-the-SSW shearing associated with a NNE-SSW regional compression event. Muscovite, biotite, and hornblende 40Ar/39Ar step-heating ages constrain the timing of shearing and the tectonothermal history of the KJSZ. Quartz c-axis fabrics and mineral deformation features indicate the defor-mation within the KJSZ occurred at temperatures of 400 degrees C-450 degrees C, which are lower than the Ar-Ar closure temperature of hornblende but higher than the closure temperatures of muscovite and biotite. Samples from the KJSZ yield 40Ar/39Ar step-heating ages from 164.6 +/- 0.5 to 165.2 +/- 0.6 Ma for hornblende samples and from 161.4 +/- 0.4 to 163.1 +/- 0.4 Ma for mica samples. Combining these ages with the temperature of deformation within the KJSZ indicates that this shear zone most likely formed between 165.2 +/- 0.6 and 161.4 +/- 0.4 Ma. Linking these new data with the tectonics and geochronology of the eastern part of the northern margin of the NCC suggests that the deformation within this region was most likely controlled by a nearly N-S compressional event associated with the far field effect of the Mongol-Okhotsk Ocean closure during the Middle-Late Jurassic.
