| 英文摘要 | A similar to 2500 km broadband digital seismic array was deployed in the South China Block and the northeastern Tibetan Plateau, from December 2009 to September 2013. Based on the teleseismic data from 130 portable stations in the South China Block of this array and 90 nearby national permanent stations, we utilize the wave equation-based migration technique on S-receiver functions (RF) to image the lithospheric structure. Our imaging results show that the lithospheric structure is dramatically distinct for different tectonic units and there are very local variations of the lithospheric structure near the tectonic boundaries. Thick lithosphere is mainly distributed beneath the Sichuan Basin. Thin lithosphere is mainly imaged beneath the Eastern Sichuan Fold Belt and the Cathaysia Block. The lithosphere is obviously thickened beneath the Xuefeng Mountain, and the lithospheric structure and feature show significant E-W difference separated by this mountain along the profile. Combining with other geophysical observations on the crust and the upper mantle, several conclusions are achieved as below: (1) The Sichuan Basin has preserved a thick and cold cratonic lithospheric root and the mid-lithospheric structure is characterized by obvious stratification. (2) The Xuefeng Mountain may be the tectonic boundary of the Yangtze Craton and the Cathaysia Block in the southwest. (3) The region to the east of the Xuefeng Mountain may have experienced lithospheric modification and thinning since Phanerozoic. The pattern of the modification is similar to that in the North China Craton, which shows different lithospheric structure on the opposite sides of the North-South Gravity Lineament. Our results could provide new insights into the tectonic evolution and dynamic process of the South China Block. |
