Abstract

The study of phytolith in the surface deposits of different sediments is a basic work of Quaternary researches such as paleobotanic recovery,paleoenvironment reconstruction,stratum contrastion,etc.Through the phytolith study of surface deposits from 41 peat areas in Northeast China,plenty of phytolith are found.They can be divided into 11 types: dumbbell-shaped,saddled,fan-shaped,square-shaped,rectangular-shaped,trapezium-shaped,crenate-shaped,cap-shaped,point-shaped,elongate,and other shapes.The surfaces of each kind of phytolith are different,most of the decorations are concave or protuberant.The Sculpture on the dumbbell-shaped phytolith can be divided into 2 kinds,fan-shaped,crenate-shaped and elongate-shaped phytolith can be divided into 5 kinds,and cap-shaped and point-shaped phytolith can be divided into 3 kinds.
