Abstract:

The Xihu Lake is Located on the southern Fildes Peninsula. A drill hole is 2. 6 m deep and total 102 samples were collected by Dr. Xie Youyu during 1985-1986. The samples from drill hole in the Xihu Lake contain abundant and well-preserved diatoms and Cysts (Chrysophata), 131 species and variaties of diatoms belonging to 21 genera were recognized. As a result of the detailed research on the diatom assemblages from the Xihu Lake sediments, 9 diatom assemblages were distinguished. From diatom and Cysts (Chrysophyta) data, the changes of the Palaeoenvironments and Palaeoclimate and their age are discussed.

Key words: Diatoms, Cysts, palaeoenvironment, palaeoclimate
