应用部分非磁滞剩磁(pARM)谱,对单畴和多畴亚铁磁性矿物携带的磁信息研究表明,多畴颗粒明显具有软的矫顽力谱,高于20mT的pARM可以有效地压抑多畴颗粒的信息.此外,pARM的比值,如pARM(5,10mT)/pARM(0,5mT),与单畴和多畴亚铁磁性矿物的相对含量呈正相关.因此,利用这些新参数能够快速地判断岩石或沉积物中单畴亚铁磁性矿物的相对含量,从而有助于沉积物的古气候和古地磁学研究.
Some non-hysteresis remanence (pARM) spectra were used to study the magnetic information carried by single-domain and multi-domain ferrimagnetic minerals. The multi-domain particles obviously have a soft coercivity spectrum. PARM higher than 20 mT can effectively suppress In addition, the ratio of pARM, such as pARM (5,10 mT) / pARM (0,5 mT), is positively correlated with the relative content of monodomain and multidomain ferrimagnetism minerals.Thus, with these new parameters, Rapidly determine the relative content of monopolar ferrimagnetic minerals in rocks or sediments, which contributes to the paleo-climate and palaeomagnetic studies of sediments.
