摘要
The Yinma River in Jilin Province is a smaller muddy and sandy meandering river, by the fine dissection, detailed observation and researches of Dayushulin point bar, the sedimentary characteristics are summarized. And furthermore, the sedimentary mechanisms of previous easy-confused microfacies such as flood plain, marginal bank and point bar are scientifically argued and demonstrated. On the basis of the above, the sedimentary microfacieses of Dayushulin point bar are divided into five types: stagnant, point bar, over bank, chute bar and over bank levee.
