The magnetic properties of topsoil samples were also analyzed. These results are used to explore the relationships between iron oxides, organic matter and grain sizes and magnetic parameters. It is revealed that magnetic parameters (χ, SIRM, χARM, SOFT) show significant positive correlations with DCB- and AOD- extractable iron oxides. There exist negative correlations between magnetic parameters (χ, SIRM, χARM, SOFT) and organic matter concentrations, suggesting that the magnetic minerals could be dissolved by organic matter in urban topsoil. The magnetic minerals are inclined to be enriched in the fine grain (especially in clay minerals), indicating that the magnetic parameters (χfd?χARM/χ, χARM/SIRM) could be used proxies for grain sizes of clay minerals in topsoil., authors=,, authorsList=;, authorCompany=null, correspAuthors=null, authorNote=null, correspAuthorsNote=null, copyrightStatement=null, copyrightOwner=null, extLink=null,

articleAbstract=通过对徐州城市表层土壤中不同类型铁的氧化物、有机质与粒径组成的分析以及表层土壤的磁学特征的测量,探讨了表层土壤中铁的氧化物、有机质以及不同粒径与磁学参数的关系。结果表明,表层土壤中游离氧化铁和无定形氧化铁与磁学参数χ、SIRM、χARM以及SOFT呈显著正相关,土壤中有机质含量与磁学参数χ、SIRM、χARM以及SOFT呈显著负相关,指示土壤中有机质能溶解磁性物质;表层土壤中的磁性矿物倾向于在细粒子特别是粘土矿物中富集,因此,磁学参数χfd、χARM/χ以及χARM/SIRM可以作为粘土矿物粒径的代用指标。,
