A suite of very large late Jurassic conglomerate layer of about 2000 m in thickness, the Fenghuangtai Formation is developed at the north foot of the Dabieshan Mt in Anhui province. It is a typical alluvial fan facies deposition with characteristic texture and structure, extending along the mountainous foot in the form of multiple fan bodies superimposing one another. Research into its gravel components will provide significant geological evidence for timing the uplift of the Dabieshan Mt.
