对采自塔吉克斯坦、中国和匈牙利的139个黄土及古土壤样品的分析来看,在所有剖面里,饱和磁化强度和饱和剩磁都随低场磁化率呈线性增加。其磁性的增强主要是由亚铁磁性矿物含量增加所致。高场磁化率(k_h)的变化认为是由粘土矿物引起,因为高场磁化率(k_h)与直径小于2μm 的矿物颗粒含量呈线性相关。磁性增强的过程可用一个综合理论模型来解释,该理论模型是以两种矫顽磁力不变、磁性矿物成分不同的集合体为基础。这个模型与匈牙利样品的结果很近似,且与塔吉克斯坦和中国磁性较强的古土壤样品数据吻合较好。塔吉克斯坦黄土样品的理论计算值和实测值之间的偏差较大。3种成分模型改进了实测数据和综合计算值之间的吻合程度。塔吉克斯坦和中国黄土磁性增强与古土壤的磁性增强机理不同,且在古气候和磁化率之间的关系方面不像匈牙利黄土-古土壤层序那样清晰。
From the analysis of 139 loess and paleosol samples taken from Tajikistan, China and Hungary, the saturation magnetization and the saturation remanence increase linearly with the low magnetic susceptibility in all sections. The magnetic enhancement is mainly due to the increase of ferrimagnetic minerals. The change in high field susceptibility (k_h) is thought to be caused by clay minerals because the high field susceptibility (k_h) is linearly related to the mineral particle content of less than 2 μm in diameter. The process of magnetic enhancement can be explained by a comprehensive theoretical model based on two different sets of coercivities and different magnetic minerals. This model is similar to the results from the Hungarian samples and is in good agreement with paleomagnetic data from Tajikistan and China. Tajikistan loess samples theoretical deviation between the calculated and measured values larger. The three component models improve the agreement between the measured data and the calculated values. The magnetic enhancement of loess in Tajikistan and China is different from that of the paleosol, and it is not as clear as the Hungarian loess-paleosol sequence in relation to paleoclimate and susceptibility.
