The Fangyan Formation io Zhejiang

Through field investigations of the Yongkan,Nanma,Dongyang,Huzheng and Xinchang Basins in eastern Zhejiang in 1980 and studies of previous data of stratigraphy and palaeontology,new results concerning the position,subdivision and correlation of the Fangyan Formation have leen achieved. 1.The Fangyan Formation overlies the Chaochuan Formation,but it may changes partially into the Chaochuan Formation.Its age is Late Cretaceous on the basis of its stratigraphic position and fossils. 2.The age of the Qujiang Group（including the Zhongdai,Jinhua and Cu- xian Formations）is Late Cretaceous;it can not be correlated with the Fang- yan Formation,because it covers the Fangyan Formation. 3.In the Ningbo Basin,members 1-4 of the sequence belong to the Fang- yan Formation,while member 5 to the Qujiang Group.
