摘要:
在野外调查的基础上，利用粒度分析和扫描电镜分析方法研究了新疆玛纳斯河下游湖积平原兴农农场剖面中砂的特征。结果表明，其粒度组成特点与现代沙丘相似。石英砂表面特征磨圆较差，有蝶形坑和水下磨光面，说明玛纳斯河湖积平原沉积环境在气候干燥时曾出现过风力堆积。
Abstract:
Based on the filed work, the sands characters of Xingnong Farm section in lacustrine plain of Manas River are obtained by means of 7 grain size analysis and scanning electron microscope observation.The results show that:the content of grain is the same to the dune.The quartz grains are subangular shape, and there are dish-shape impact pits or polished surface under water environment in their surface.This information suggests that there were sediments which were piled up by wind force in lacustrine plain when the climate was dry.
