Down-core variations of normalised relative paleointensity and ARM/SIRM after...

The concentration in ferromagnetic particles is much lower in the interglacial sediments than in glacial sediments. Therefore, the NRM needs to be normalised by a...间冰期沉积物内的铁磁性颗粒浓度远低于冰期沉积物。因此，天然剩余磁化强度（Natural Remanent Magnetization，NRM）需要通过……进行归一化处理。
