Through the field exploration,we have established the unconformity,distributed eastern of Taocuen fault, between Taocuen conglomerate and Jurassic Laiyang group and Cretaceous Wangshi group,This unconformity is beieved to be the result of a crustal movement which happened at the end of Cretaceous period,May its occurence be in Tertiary period? The analysis of structural location and enviroment of Taocuen conglomerate has shown that it was controlled by the movements of Taocuen fault,which is important to the research of both the evolution of Taocuen fault and Taoeuen basin and the historical evolution of Jiaodong district after Mesozoic era.
