1Susceptibility variations of multiple origins of loess from the Ily Basin(NW China)显示文摘The magnetic susceptibility of loess from the Ily Basin,northwestern China shows maximum values in S0 paleosols but minimum values in other paleosols,the mechanism of which has been well debated.In this work,systematic magnetic measurements were made on a representative section from Neleke county.The results show that the loess horizons(L1,L2 and L3) have multi-domain magnetite grains of aeolian origin,S0 is characterized by production of pedogenetic ultrafine-grained ferrimagnetic minerals,and the other paleosols(S1,S2,and S3) are characterized by the formation of nonferrimagnetic minerals associated with waterlogging.The correlation between the low concentration of ferrimagnets,high paramagnetic content,high magnetic coercivity remanence,fine ferrimagnetic grain size and intensified pedogenesis suggest two competing processes of pedogenetic enhancement and pedogenetic depletion in the lower paleosols.Pedogenetic depletion dominates and is responsible for the low susceptibility.Changes in magnetic grain size distribution occur during pedogenetic depletion.The susceptibility variations are of multiple origins in the loess of the Ily Basin.Pedogenetic enhancement,pedogenetic depletion,and allochthonous input of magnetic minerals should all be taken into account to explain the variations of magnetic parameters.CHEN Qu LIU XiuMing HELLER F HIRT Ann M LU Bin GUO XueLian MAO XueGang ZHAO GuoYong FENG Hua GUO Hui 2012Chinese Science Bulletin2012,57,15:9
2伊犁黄土磁化率的增减及其成因显示文摘中国伊犁黄土磁化率一般在S0最高,但在其他古土壤层低,磁化率增减机制存在争议.对尼勒克县的一个剖面进行系统的磁学研究后发现,黄土层含有风成多畴磁铁矿,S0含有较多成壤成因的超细粒亚铁磁性矿物,其他古土壤层含有较多过湿条件下形成的非亚铁磁性矿物.非亚铁磁性矿物高含量、高矫顽力、亚铁磁性矿物低含量与较细的磁颗粒粒径对应于较高的成壤强度,揭示存在相互竞争的磁化率成壤增强过程和成壤削弱过程,以成壤削弱过程为主,导致磁化率降低.成壤削弱过程中,磁颗粒粒径发生变化.伊犁黄土磁化率变化成因多样,对磁学参数的解释要全面考虑磁性矿物的风成输入和成壤成因的磁性增强及磁性削弱作用.陈渠 刘秀铭 HELLER F HIRT Ann M 吕镔 郭雪莲 毛学刚 陈家胜 赵国永 丰华 郭晖 2012科学通报2012,57,24:4
