Significance of surface soil magnetic susceptibility in the Tengger Desert
摘要
Abstract
The magnetic susceptibility of soils is crucial for paleoenvironmental and paleoclimatic studies.How-ever,debate persists regarding whether soil magnetic susceptibility can serve for paleoprecipitation reconstruction or reflects changes in prevenance in arid regions.To address this issue,new magnetic measurements were con-ducted on modern soil samples across the Tengger Desert,on the edge of the East Asian summer monsoon region.The weak correlation between the soil magnetic susceptibility,frequency-dependent susceptibility,and modern mean annual precipitation(R2=0.01 and 0.02)suggests that precipitation is not the primary factor driving varia-tions in the surface soil magnetic susceptibility in the Tengger Desert.Conversely,distinct magnetic differences among arid regions indicate that soil magnetic susceptibility can differentiate between origin areas.These find-ings underscore the need for careful interpretation of soil magnetic susceptibility when conducting climate and en-vironmental research in arid regions.关键词
