| 摘 要： | 埃及Faiyum盆地是尼罗河下游的泛滥平原,沉积物主要来自尼罗河和撒哈拉沙漠.本文通过对钻孔FYAM(孔深4.6m)沉积物的粒度、磁化率的分析,并结合石英形态、石膏和碳酸盐含量分析,旨在寻找Faiyum盆地沉积物中代表风沙活动的粒度、磁化率特征.研究结果显示,钻孔沉积物中共发现7种粒度频率曲线类型,主要为细粒组(6-2... |

| Abstract: | The Faiyum Depression,a flood plain of the Nile downstream,receives sediments from the Nile and the Sahara Desert.By means of grain size and magnetic susceptibility analysis of sediments from core FYAM(4.6m deep),combined with surficial characteristic of quartz grains,occurrence of gypsum and carbonate contents,the paper is aiming to reveal some indicators for eolian activity in the Faiyum sediments.The results suggest that there are totally seven patterns of sediment grain-size distribution,including unimo... |
| Keywords: | Grain-size distribution unimodal pattern biomodal pattern Sahara Desert the Nile surficial quartz characteristic Faiyum Depression |
