Detrital Garnets from Cenozoic Sandstones across Boxing Sag for Provenace Indicator and Its Implication for the Luxi Uplift

Key words: 
• Cenozoic

Abstract: For a long time, the evolution relationships between Luxi uplift and peripheral basins during Cenozoic is a research hotspot.In this study, Boxing Sag has been selected as the target area, and the evolution history between Luxi uplift and peripheral basins has been discussed on the basis of the analysis from the exact high spatial resolution for the detrital garnets from Cenozoic various horizons, and the exclusiveness of garnets compositions and their content variation. The results show that the primary provenance of Boxing Sag were from the Luxi uplift and Jiaodong terrane during Cenozoic, more importantly Jiaodong terrane. The content variation of detrital garnet implies that Luxi uplift had been rising up quickly during early Neogene, and two smallscale uplifts has been conjectured from Paleocene to early Eocene and from late Eocene to early Oligocene respectively.
