It shows that the magnetic susceptibility of the sediment is related to its grain size and rock type.Conglomerate has lowest susceptibility, and siltstone,muddy siltstone,and mudstone have a relative large value of susceptibility. The susceptibility of mudstone of different color varies with the degree of oxidation and organic content.

结果表明，沉积物磁化率的大小与沉积物的粒度及岩石类型有一定的关系：砾岩磁化率的峰值最低，粉砂、泥质粉砂岩和泥岩的磁化率峰值相对较大；不同颜色的泥岩也会因氧化程度、有机质含量的不同而表现出不同的磁化率峰值；磁化率曲线变化是剖面岩性和沉积旋回的一种反映。
