Based on the analysis of lithological features,microfossils,sporopollen and 14C dating of the core SO4 samples from the Chaoyanggang lagoon,the stratigraphic of the core is divided into four beds including the con-tinental bed,the coastal bed,the lagoon bed and the lagoon-marsh bed,and the sporopollen zones of the core hav.

The evolution processes of the Chaoyanggang lagoonal wetland since the middle Holocene have been discussed on the basis of systemic analyses of the main factors in developing of the wetland.

On the basis of the field investigation in Hougang lagnoon and nearby Meye island area,this paper discusses the formation and evolution of Hougang lagoon which formed after the post-glacial maximum transgression,according to the data of core SO2 such as size of grain,~(14)C data,forminifera etc.

Based on the stratigraphic, structural features and the types of ore deposits in Lingshi, it is concluded that the gypsum was deposited in supratidal lagoons.

Sedimentological studies of coal-bearing member of Ceshui Fomation inLengshuijing coal mine indicate that it is sediments of depositional system of barrier is-land-lagoon and shows vertical sequence from regression to transgression,Coalaccumulation is influenced by depositional environments in a great degree.
