摘要(Abstract)：

对湖光岩玛珥湖82个表层沉积物样品进行粒度分析,计算平均粒径、分选系数、偏度和峰度等参数。结果表明:湖光岩玛珥湖表层沉积物主要包括泥、粉砂、砂质粉砂和粉砂质砂4种类型。粉砂和泥在湖内分布范围最广,为主要沉积类型;砂质粉砂和粉砂质砂主要分布在近岸区域,分布范围较小。沉积物平均粒径(Φ值)变化范围2.1~7.5,平均值为6.8,粒度具有由岸向湖随水深增加而逐渐变细的趋势,但在部分近岸区域,由于雨水汇集入湖导致粒度参数变化剧烈。靠近湖岸和火山岩壁,沉积物颗粒最细的区域并未出现在湖水最深处。湖光岩玛珥湖的表层沉积物频率曲线表现为4个明显的组分峰值,尽管沉积物质主要来源为四周火山岩风化产物,但是远距离搬运的细颗粒仍然对沉积物的粒度组分产生较大的影响。
