摘要
This paper takes Zibo, Linqu,Pingyi, Mengyin Basin as the key study area.Through composition analysis of fragment garnet in Mesozoic sandstone,the authors discuss the tectonic evolution history of West Shandong uplift and the surroundings in Mesozoic. The research shows that garnet composition of Luxi Basin changed from Early Mesozoic Jurassic to Mid-Late Mesozoic Jurassic implying that the provenace of Luxi Basin shifting. In Cretaceous period the mainly provenance of Luxi Basin was Jiaodong area and Luxi uplift had little contribution in provenance supply,but the provenance supply of Luxi uplift shifted in mid-Qingshan Formation and mid-Wangshi Formation. In Cretaceous, Sulu Orogen belt controlled the sediment of Luxi Basin. Paleogeography framework indicates that the terrain of Shangdong is higher in the east and lower in the west. The shifts of garnet provenance in Cretaceous showed that West Shandong uplift was probably uplifted in mid-late period in Early Cretaceous and mid-late period in Late Cretaceous.
