摘要
对河南洛阳寺河南剖面为一套全新世湖沼相沉积进行了磁化率测试,并与剖面的粒度变化进行了对比分析,分析结果显示沉积物磁化率的变化与不同粒级的百分含量具有一定的相关关系,频率磁化率与细粉砂和黏土的百分含量呈正相关关系。受湖泊状况和沉积条件的影响,沉积物磁化率与粒度参数的关系需依据不同的沉积环境进行分析。
Magnetic susceptibility of a profile of Holocene lake sediments was tested, and compared with the changes of grain size. The results show that magnetic susceptibility of the profile is of some relationship with that of the contain of different grain sizes, and the frequent magnetic susceptibility has positive correlativity with the percent of fine silt and day. Due to the different condition of lake and aggradation, the correlation between magnetic susceptibility and grain sizes should be analyzed depend on deferent sedimental environment.
